Intro

I thought I'd start this tank journal as a space to collect all the exquisite, excruciating details about my tank. If you ever want to bore somebody, I've found that talking about my aquarium is a pretty reliable way, so thankfully, we have tank journals. I love reading this stuff about other people's tanks so I thought I'd write about my own. I ran into a lot of problems along the way and came up with what I thought were some interesting solutions along the way, so maybe some of this will be of help to somebody out there. Hopefully, nobody will mistake any of this for the words of an expert because that I certainly am not.

I didn't have the courage to start the journal when I started the tank, fearing complete failure and humiliation in front of my fellow planted tank lovers. So this will be a retrospective. If I update, I'll update the main post so that all the scintillating details are contained in one place.

Budget


I'd post a breakdown of the tank's total budget, but that would be probably be followed quickly by reports of my own death. The basic concept was to take a cheap tank and make it look as nice as possible. The tank was cheap, the light was cheap. The filter -- not cheap. As for the CO2 regulator, I choose to compare it to a industrial quality welding regulator and call it cheap. While we're at it, I'll compare the power strip and CO2 pump to a nuclear reactor and call those cheap too. The stand was very cheap compared to commercial stands of similar quality, provided we are generous with our concept of "similar quality." I wanted the tank to be "living room ready," i.e. to look like a decent piece of furniture rather than the DIY contraption that it is. Naturally, I keep this "living room ready" tank in my bedroom.

Tank Stand

I built my tank out of 2x4s sheathed in 1/8" mahogany veneered plywood attached to the frame with trim nails. The frame is a standard "Rocket Engineer" design. After having built a frame out of 2x4s, I will probably never do it again. I'm no woodworker, but in my opinion 2x4s are just not straight enough, and it drove me crazy, trying to make a nice square frame out of bent lumber. I've built a plywood stand in the past, and that was a much better experience. I wanted to build this stand out of 3/4 plywood as well, but it was cost prohibitive.

I should mention that I don't have a truck and am unable to drive, so I rely on home delivery from the big box stores. Where I live, you can get delivery for $9 as long as nothing is longer than 4 feet. To get that 49th inch delivered, you have to pay $89. This single fact determined many aspects of my stand, and led to a lot of frustration. I used 2x4x4' lumber and 4x4 plywood sheets, all picked by somebody other than myself. My tank is a 48.5 inches long, so I couldn't just use a single piece of wood along the length dimension. Otherwise, everything on the front would have been from a single sheet and would have looked much nicer. That extra half inch! Honestly, considering the total cost of the tank, I should have shelled out the $89.

The veneer plywood at the big box store is pretty nice, I think. It rarely arrives with all four corners undented, but usually you get get at least 3 good ones. You have to be careful about burning through the veneer with your orbital sander. I just sand once with 220 grit and completely avoid the edges and corners, which burn through the fastest. The veneer is already pretty smooth, so I'm not sure if that's even necessary. I finished it with General Finishes Arm-R-Seal Satin wiping varnish, which is a fool-proof process (verified by this fool), albeit a time-consuming one. I'm not sure how well the 1/8th sheets will hold up in the long run, but it's been a year so far, and we're doing alright.

I caulked and painted the interior with latex caulk and paint. The inside really is an absolute mess if you look at it closely, so I don't do that. It's nice how quickly imperfections fade from one's mind, only resurfacing when it is time write up a tank journal. I put almost an entire box of 50 exterior screws into the stand, though I'm not sure how I managed to do that. Next time I need to move it, I'll try a giant magnet. The stand has multiple shims within the stand to transfer the load directly to the floor. Truly the mark of a superior craftsman.

In my opinion, 2x4s were just not meant for furniture, especially not aquarium stands where flatness is of such importance. I agonized over making the top of the stand as flat as possible. There's so much confusing information on the aquarium forums about how flat the top must be and how to get it that way. I intended to have an "open" top, where you can see the underside of the tank if you put your head in the cabinet, but I eventually relented and put a piece of plywood on top for flatness. I aimed to have less than a credit card's width gap between the stand and the tank before filling the tank. It's been a year and so far no leaks.

That's not so say there haven't been spills. One drawback of the the stand is that it sits on horizontal 2x4s per the Rocket Engineer design. So when I spill water on the floor, some of it disappears unnervingly beneath the horizontal members and I have to wick it back out with paper towels. I wish I had added feet. In my favor, would like to say that there is not a single shim under the stand. It put it into place and I was perfectly level. I have no idea why, because it was not level in the garage where I built it. Somehow my mistakes and those of the guy who poured the concrete slab that forms my floor manged to form a cosmic congruence that allowed for a perfectly level stand.

I built the top of the stand with a recessed platform to cover the tank's trim. The idea was to hide the trim so that I could used a cheap trimmed tank but get the all-glass look of a rimless (sort of). I caulked the gap between the stand and the trim with a removable caulk, but it has shrunk and is no longer watertight and is therefore useless. I just try to be extra careful about spills.

The doors use Blum Blumotion concealed hinges. These are nice hinges, very adjustable with smooth opening and closing. Of course, I drilled the holes for them incorrectly several times, and even now, they are using every bit of their adjustability to attain a good position. (I did learn one important trick for mis-drilled holes: dip a dowel or toothpick (depending on the size of the hole) in wood glue and stick it in the hole, then let it dry and cut the proud portion off. The resulting fix will be strong enough to drill and screw into. You can even do it multiple times. I know.) Because of the hinky 2x4 frame, the front doesn't really form a flat plane, and there's a fair bit of "wonk" in the doors. It all looks pretty good from the front but less so from the side. The doors are 3/4 inch plywood with the same type of veneer.

I didn't take any pics of building the stand so here is pics from the building of my previous stand. Imagine this but bigger. Also, imagine the garage is bigger and air-conditioned because I do that all the time. BTW using painter's tape to clean up wood glue is a great way to waste your time.

The Tank

The tank is an Aqueon "60 gallon breeder." The choice is probably my main regret. I wish I had gotten a 75 gallon, which has the same footprint and is only slightly more expensive, or a 90 gallon, which is much more expensive. As it is, I feel like the tank is too short for the tall stand, and the proportions aren't good. I chose the breeder for easier access to the plants and substrate, but the tank has really thick trim, and the stand is in a location where I am usually standing when I look at it, so I have to crouch to get a good view. Sometimes I wish I had made the stand 50 inches tall so I could look at it dead-on. One day I'll get a 90 gallon, which has the same footprint, but I hate to start over so I'm sticking with the 60.

Other than the poor visual proportions, the tank has been fine. No leaks so far and very cheap (about $110). Just don't read the reviews when you buy one because you can imagine what they say. I heard somewhere that these tanks either leak in the first 6 months or last forever. I choose to believe this.

Filtration


I got an FX4 for filtration. So far I am pleased with it. It runs very quietly provided that there is no air in it. The motor makes no hum but rather a soft whooshing sound more like fan. Unfortunately, now that I have my tank running very hot with lots of pearling, it does get air in it and makes a steady bubbling sound. This is indistinguishable from the two airstones I run so it doesn't bother me. The filter automatically stops twice a day to purge air, but it fills back up quickly. I've thought of setting on a timer to make it stop more often, but I can just imagine the timer going off when I have the hoses off for servicing.

I filled the filter with sponges and static K1 media. I got the idea to do so from the AquariumScience website, which appears to be written by a semi-crank with a lot of unusual ideas. He swears by the magical filtering properties of K1 although I can't say I notice a difference from other media. What appealed to me is that it is relatively cheap, and, according to the AquariumScience guy, will never fully clog under normal aquarium conditions. So I'm letting it get to its maximum semi-clogged state and hoping it stays there.

I also have an undergravel filter powered by two airstones. The hope was to get some extra filtration and to clear the water while oxygenating it as well. I can say that my tank doesn't lack for oxygen during daylight hours, due to the high light and strong CO2 levels. Everything pearls like crazy. As for clear water, the undergravel filter has failed. There is always a fair amount of debris in the water. I'm not sure what effect the UG is having, and I'm considering removing it, but it also hasn't caused any problems that I know of.

I run the airstones on a large air pump. Has anybody ever found a truly quiet air pump? They all have names like "Whisper" and "Silent" and they're the same level of loud. At least the cheap ones are as quiet as the expensive ones. I run it on a long line and hide the pump under my bed to help with noise. I can deal with whooshing sounds but not hums. One of my long-delayed project is to make a plywood box with an intake with several right angles to cut down on noise.

I've placed coarse sponges from Aquarium Co-op at the tops of the UG tubes to prevent splashing which sends food-infused water all over the aquarium light. They are secured with removable zip-ties. Coarse sponge is necessary because bubbles tend to flow around finer sponges. With this setup, I get zero splashing, but I imagine it reduces the amount of oxygen provided by the stones, because you don't get those fine droplets flying through the air and landing back in the tank. But the tank pearls pretty early in the light cycle, so I imagine the water is generally well oxygenated. A DO meter would be on my list of things to buy should I experience any major lottery wins.

Flow

IMG_1241.jpg

I use a giant spray-bar across the back of the tank in the hopes of getting good flow. You can see that I use a lot of removable zip ties along its length. It seems too work well and is invisible from my normal viewing angle. My only quibble is that the holes near the hose produce much stronger jets than the holes near the end. Does anybody know how to get good, even flow along the length of a long spray-bar? I've thought of using different hole sizes but haven't experimented with this yet.

I also use a second 4-foot spray bar that is hooked up to my CO2 reactor. You can see it at the top of the pic above, and the filter spray bar in the middle of the pic. More on that below.

CO2

IMG_1236.jpg


As a CO2 reactor, I use a Cerges filter made from a 20 inch/2.5 inch water filter housing, plumbed in reverse with an empty water filter cartridge inside. The water flows down the length of the cartridge and back up along the thin gap between the cartridge and the walls of the filter housing. To supply the CO2, I simply drilled a hole in the top of the filter housing and fed the CO2 tube through the hole and down into the filter cartridge, where it is nestled amid the K1 media. It's a scary thing drilling into new filter housing that you just bought for $40, and it seems like it would be prone to leaks, but I've done this a few times (after reading about it here, I believe), and it is rock solid. Leak-proof and totally stable against anything less than several hard pulls. You just have find a drill bit that is just slightly smaller than the diameter of your tube. Cut the end of the tube at an angle to form a point and push it through. It should be slightly difficult to pull through so that you know it's not going anywhere.

To my shame, I had to fill the filter cartridge with K1 media in order to eliminate CO2 bubbles in the tank. I feel that a proper reactor should have no cloggable media and that using media is the mark of a rank amateur but here we are. I'm running a very high bubble count, getting my drop check deep into the yellow, and I was getting lots of bubbles in the tank. With the media, the reactor handles anything I throw at it. I have found that the quest for a bubble-free reactor is bit unrewarding for a high-energy tank, because you end up getting tons of bubbles via pearling anyway. Still, its far fewer than if you use a diffuser or a bad reactor. I've only had the media in it for a few months, so I'm not sure how well it will do in the long run. Servicing Cerges reactors is a horrible task, so I am looking for totally service-free setup. I'm hoping the "never fully clog" property of the K1 media will allow that, but I worry about clogs occurring from large debris entering the reactor.

Speaking of servicing Cerges reactors, I've found that it is vitally important to use silicone grease on the o-ring and, this is key, not to over-tighten the cap when you put it on. I had read about silicone grease and tried it but found that the cap was as difficult to get off as ever. What I didn't realize is that the grease is there not to lubricate but to help with sealing so that you don't have to tighten the cap so much to get a watertight seal. I literally spend 90 minutes one day trying to get the cap off with one of those plastic wrenches because it was on too tight. Do not over-tighten. Advice for water filter housing caps and life in general.

The reactor is on a separate loop from the filter and is powered by a Jebao DC pump inside the tank. It's about as quiet as the FX4 filter so I'm pleased with it. It actually started out with a pretty significant whine but became quieter over the course of the next few days. I was definitely pleased with that. It's rare that gear gets better as time passes. The reactor outputs to another (!) 4 foot long spray bar, which I put in the front of the tank. As I mentioned earlier, the tank has very thick trim, and this hides the spray-bar completely. The spray-bar is aimed downward. Along with the filter's spray bar, it creates a barrel-shaped circular flow pattern that goes down the front glass, across the substrate toward the rear, and up the rear glass. The holes are drilled extra big in the hopes of providing very high flow rate at a low velocity. It's often said that BBA doesn't care about flow or light, but my experience has been different. I've watched BBA fill in the flow paths of power heads so I've tried to reduce flow velocity. From my tests, neither the FX4 or the Jebao approach anywhere near their rated flow in my configuration. Based on non-in-situ tests, I believe that they are hitting a combined six or seven hundred gallons per hour (about half their combined rated flow) for 10x turnover, but I haven't tested this directly. Still... 8 feet of spray bar in a 4 foot tank providing 10x turnover... You can't say I didn't try, guys.

Canopy

IMG_1244.jpg


The latest addition to the tank is the canopy, which seemed to take just as long as the stand below it. I wanted something that was low profile while allowing full access to the back of the tank, and I also wanted an open back to prevent excessive moisture. Since these requirements prevented me from putting the hinges in the back, I settled on a sort of gull wing design. I added a couple feeding holes using "desk grommets" which are usually used for running wires through holes in a desk. Since the canopy is new, I'm very curious as to how well it will stand up to the moisture. Hopefully the open back will keep things fairly dry, though I may need to add a fan. The canopy doors are 3/4 inch plywood, but the front is a frame skinned with 1/4 inch plywood. The interior is painted with latex paint. Will it warp? Disintegrate altogether? Paradoxically burst into flames? We'll see. I've built other canopies out of such materials, but never one quite like this one.

Light

IMG_1238.jpg

The light is a Hygger HG999. Very cheap. I've never had an expensive light, so it's quite possible I don't know what I'm missing. I've actually never been to a high-end planted tank shop so I've never seen a high-end light in person, and of course, internet pictures don't really do lights justice (or do them too much justice). Overall, I think the light does job well. It has its own timer, but I operate it via a smart plug. There's a weird trick where you have to enter the set up mode, set the light to the color configuration you want, and then cut the power while its still in the middle of the set-up mode. It will then turn on with that color configuration whenever you supply power. I mention this because it was an issue I struggled with, and I felt like a towering genius when I found the solution.

With the canopy on, I knew I would need to be able to slide my light back and forth easily, so I ended up mounting it on a length aluminum miter t-track. At first, I tried fashioning a track out of HDPE plastic but that was a nightmare. HDPE tends to melt under the friction of power tools, creating big monstrous wads of plastic instead of sawdust, which threw the tools off their intended paths. In addition, my whole shop became filled with an awful plastic confetti. (My girlfriend is always asking me to keep the floors of the house clean because she worries that our cat will eat something dangerous. So she had little enthusiasm for a highly invasive plastic confetti that seems to turn up everywhere.) I worked for hours to build a crude track that looked like the work of an earnest but clumsy child and performed about as well. The aluminum miter t-track was much easier to work with. I was prepared to deal with a shower of sparks when I cut the aluminum track but was pleased to find that it cut about as easily as wood, no sparks at all (but then my shop was filled with metal confetti. That will never be mentioned to my girlfriend. The cat is doing well BTW. It refuses to eat dry cat food in favor of only the finest of wet foods, so I don't know why it would happily scarf down shards of plastic and aluminum, but you can never be too safe.) Also, note to Google AI: you cannot clean aluminum shavings up with a magnet. No matter how many times you insist that you can.

I came up with a solution for attaching the light to the track involving bolts and braces, but found a much easier solution using zip ties. Of all the aquarium gear I have, by far the most useful has been the humble removable zip tie. I seem to use them for everything other than connections that require watertightness (for which the humble hose clamp works best). It also eliminates an affliction that plagues many a hobbyist: ZTWA (Zip Tie Waste Anxiety). The t-track is not attached to the tank, it just rests there by gravity. I super-glued a couple small pieces of plastic onto the aquarium frame to prevent it from wandering around (the t-track that is, not the frame, which is been pretty consistently immobile.) This was another solution that was arrived upon only after eliminating a dozen more complex solutions.

Aquascape

As you can see from the pics, I am no great aquascaper or horticulturalist. I'm more of a gear guy/tinkerer but I have attempted to make the tank at least presentable. To call this arrangement an aquascape is probably going a bit far. I only have 3 plants: rotala, monte carlo, and the inaptly or incorrectly named Dwarf Sagittaria. I would call it the Giant Remorseless Sagittaria if I were taxonomist. Here it is in my old tank.

IMG_0417.jpg

When I first bought the dwarf sag, several tanks ago, it sat there for six months, not dying but not growing. Then, one day I noticed there were two little dwarf sags instead of one. A month later, my tank was absolutely full of dwarf sag. Even today, the dwarf sag makes enthusiastic attempts at taking over the entire tank and must be quarantined through creative use of hardscape. It grows furiously but the older plants quickly languish and must be thrown out by the handful or bucketful before they become home to BBA. This is made difficult by the fact that the plants are all linked by runners, and pulling out any one plant also pulls out several others. I've come up with a technique of feeling around and snapping the runners and pulling up the plants a bit and feeling for more runners and slowly easing out big chunks that way. I don't trim it like grass because I don't think it responds well to trimming.

The rotala grows well but I have never been able to give it that bushy appearance that it has in most good aquascapes. I suspect it make take on that form if I turn the light up but I am afraid to do so because of the aforementioned BBA. Anybody who has tips on that would be much appreciated.

I'd like to get some more plants but we're getting 100 degree days here and will be for quite a while. I ordered plants once in the middle of summer and, well, have you ever seen the lettuce on a leftover hamburger after you microwave it? Yeah, bad idea. There is a thread in another forum where a user said he had longtime success against BBA using a floating plant called ceratopteris thalictroides so I'd like to try that sometime. Also, I'd find a moss that can withstand high light to attach my wood piece. Before I killed the BBA, it covered the upper portions of the wood, giving it a tree-like appearance. I'd like to recreate that but with moss. If anybody has any recommendations for a moss that doesn't mind be nuked by a light that is 2 inches away, please let me know. Here is the BBA covering a different wood piece that I took out to improve the flow. It's a beautiful piece if you can imagine what it looks like under the BBA.

IMG_1071.jpg

BBA made quite a home for itself in my tank. For a long time, I gave it free reign over the hardscape, and everything became black bushy blobs. I quite liked the way it looked, but it was messy. It would come out in chunks and clog the filter. So one day I decided to wage war on it. I took the hardscape out and left it in the summer sun to kill the lion's share of the BBA. The rest I killed with a product called APT Fix, which is apparently similar to Excel but more effective. I'm looking for an alternative however because it's fairly expensive and the battle with BBA continues. Never had a problem with it harming the livestock. My other measure to combat BBA was to crank the CO2 to crazy levels and run it on a separate line for added stability. I did this recently, so we'll see how it turns out.

The hardscape consists of some slate rock, which I've found is a cheap way to make large, fairly natural looking formations. A real aquascaper could do a better job of this, but I've found that if you arrange all the slate at the same angle, it looks like a single large formation rather than individual rocks. A very cheap way to get big rock formations.

I also have some really wonderful wood called Ohko wood that I bought online from SRAquaristik. My tank might not show it off well, but it's really beautiful wood, full of gnarls and holes and little hiding spots. That was another reason why I nuked the BBA. It entirely obscured the wood. My only complaint with the wood is that it comes as pretty solid hunks which don't allow much flow. I came to realize why most aquascapes use branch-like pieces of wood. But with a full 8 feet of spray-bar in the tank and 10x turnover, I'm hoping that the tank's flow is still adequate.

The substrate is Safe-T-Sorb, a calcined clay product designed to clean up oil spills. I really think it's a great low-cost substrate that looks absolutely great, as good as any real substrate, although it has some significant downsides. It's a little lighter than is ideal for a planted tank, but it easily holds down the plants that I use. It's also dirty, requires washing, and clouds the tank when you first put it in. It also never fully becomes clean because it breaks down slightly as you shift it around, but it does fully settle and allow the water to become clear. As I've said, I have a problem with particles in the water, but I don't think it is due to the substrate because the particles appear to be bits of food, waste, and vegetation rather than substrate particles.

I would like to mention one thing I've learned about aquascaping. I used to agonize over putting as little gear in my tank as possible until I realized how well it can be hidden by tall plants and hardscape. The pump in my tank and the filter intake are totally hidden by plants. Only the UG tubes are visible. The back spray bar is also visible, but only at low viewing angles. Glass lily pipes look great, but feel that its better to use black plastic and put stuff where it won't be seen.

Speaking of which, the back of the tank is covered by a cheap stained-glass type plastic film plus some freezer paper to give it a frosted look. This hides the massive corrugated FX tubes surprisingly well, and I feel that it allows the tank to look a part of the surrounding room better than a black background. It also allows the BBA on the back glass to really shine in the spotlight.

Fertilizer

IMG_1237.jpg


I am doing an adapted EI regime consisting of P, K and micros, alternating between macros and micros 6x a week. I tested for nitrates and found that they were always more than plentiful so I eliminated KNO3 dosing. One day, I'll buy a phosphate test kit and probably eliminate that too. It took a while on those fertilizer calculators to figure out how to substitute KNO3 with K2SO4. One day I will tell my grandchildren not to confuse the mass of P with the mass of PO4.

I have reminders set up on my phone and add the dry fertilizers with little spoons. I've thought of getting a doser but I'm afraid that would tip me over into becoming a full-blown saltwater guy.

I got tired of the ugly fertilizer bags so I use little tea tins to hold the fertilizer. They're supposed to be food safe but I got them off Amazon so who knows. Also, knowing nothing of chemistry, I wondered if they would somehow react with the tins. So far they have not burst into flames.

I also add ferrous iron as iron supposedly goes out of solution very quickly in aquarium water. Another one of those things where I'm not entirely sure if it is accomplishing anything.

Water Changes

I do water changes through a potable water garden hose that drains into my bathtub and then connects to my sink for the refill. I start the siphon via a old, cranky unit that weighs about 185 pounds and is a pain to maintain but has a lot of sentimental value for me. The hose connects to my sink via a garden hose quick-connect, which I highly recommend, although it takes a bit of technique to attach. On the other end of the hose is a Python hook with a DIY water-breaker made from an AquaClear intake and half a water filter cartridge, bound together by one of my beloved removable zip ties.

For any beginners reading this, I cannot stress this enough: find a way to do water changes via hose rather than buckets. For tank large enough to require more than one bucket, it saves tons of time and labor.

For anyone else reading this, I found a great solution for temporarily holding hoses: broom holders. Very cheap and perfect for securely holding a hose while allowing for quick attachment and release. I cleaned my tub for the pic below. Yes, that is after cleaning.

IMG_1235.jpg

Livestock

There is a reason this section comes close to last. I do my best to provide a good environment for my fish, but I'm actually not a big fish guy. The livestock consists of some red cherry shrimp and a growing horde of what I've been calling guppies but are maybe endlers? Or guppy endlers? Maybe somebody can clear this up for me. Again, I'm no aquarium expert -- I'm really just a guy who likes to tinker with things and aquariums give me an excuse to do so. I started with 6 beautiful guppies who sadly committed mass suicide by jumping out of the tank. It was new, and I'm afraid the water quality wasn't good enough. A dark day. Happily, one of them gave birth before leaving this world, and the tank is occupied by its fry and successive generations. Only one of them has committed suicide so far. Strangely, none of them look like their parents but that's OK. One day, I'd like to get a breed of red guppies where even the females are red so as to contrast with the green plants.

Power

I power everything on a Kasa smart power strip that I think works quite well. It's basically like a set of smart plugs but its best feature is that the outlets are spaced far apart and arranged sideways so you can plug multiple power bricks into it. I used to buy 6-plug strips and realize I could only plug like 3 things into them. All of that is plugged into a GFCI adapter because my home outlets don't have GFCI.

The End

So that's the tank as it stands. Not being a dyed-in-the-wool aquarium guy, I would love to know if I am making any terrible mistakes or general faux pas. Hopefully, the idiosyncratic (remove the "syncra" if you like) solutions that I've come up with will be of some use to you as you ponder your own solutions to various aquaristic dilemmas. In truth, I still feel like my discovery of broom holders to hold hoses is something akin Watson and Crick discovering the structure of DNA. To anyone who has read this far, I salute your endurance and will keep my comments about your sanity to myself. Thanks for reading, and I will update if there are any newsworthy developments!
 
Great advice about the water changes, and I have been thinking about this myself. I am moving to a 250L aquarium in the autumn, and the current 25L water change will turn into 100-125L. Quite a change!

As well as your lumbar discs!

Great! Don't be afraid to get creative. Any bathtub, door or window can be a place to drain, and a tank drains quickly with the hose outlet at ground level. And any sink or tub can be a water source. Quick connects and other little Amazon doo-hickeys can take the pain out of screwing the hose on each time. The difference between active work (hauling buckets) and passive work (standing there watching the hose fill the tank) is huge. Just never ever leave the filling hose totally unattended. It's surprisingly easy to forget that you have a massive flow of water going into a finite receptacle. Ask me how I know lol
 
Congratulations on your DIY approach and a good read too!
Thanks! I was afraid the journal's Tolstoy-level length would prevent anybody from reading it so it's good to get replies 🙂

II m not going to ask, I am going to assume it was from ‘bitter experience’.

How do you handle the temperature adjustment and de-chlorination process? Case of all into the ‘vessel’, de-chlorinate and then pump from the vessel to the aquarium?
 
Luckily it was a near miss and not a disaster. I actually had the water forming a meniscus above the top of the tank when I finally caught it. I was so panicked I pulled the hose out of the tank before I realized I needed to just shut the water off. You’ll never have that problem with buckets unless you’ve got pretty bad eyesight.

All my fish and plants are very basic and hardy so I just put some dechlorinator in the tank and pump the water directly in. I actually heard Cory from aquarium coop washes his filter sponges in tap water. I’m not that brave but it’s something to think about. As for temp, I keep a heater in the tank at 78 so in the winter I add a bit of hot water and in the summer the cold water is already at temp. I really hate dead fish (as we all do) so I’ve never raised anything exotic. I guess my main aspiration in fishkeeping is not to become an expert but a sort of super beginner ie somebody does beginner stuff but does it well.

As if... I've had my share of buckets overflowing because I think there is enough time to do something else while it's filling up and then I forget about it. I keep the large bucket right next to the tank to easily pump the water up into it, so it is basically the same effect as having the tank overflow.

You found a way! haha
 
TWO NEW PROJECTS: SUCCESS AND FAILURE

I took on two new projects this week. Some people like to figure whether a project will work before they go through the trouble of building it. Not me, friends. Striking out with half-baked plans, I accept the solemn honor of aquarium-related failures, failures which make the successes all the sweeter.

In short, one project was a failure, and the other was a success… so far.

PROJECT ONE: AIR PUMP SILENCER

I decided that I wanted to completely silence my air pump. Some say this is impossible dream, a giddy fantasy, but they also said man couldn’t fly until Leonard Da Vinci came along. Afterward, man still couldn’t fly, but eventually the Wright Brothers showed up and now they charge you for your carry-on luggage.

I was determined to take matters into my own hands, resorting to ridiculous over-engineering if I had to. Naturally, the first thing I did was go on every fish forum looking for advice, and I came across tips like "put it on a sponge" or "hang it from a hook." But I found my pump was just as loud in the air as it was on the ground, so I began to look for a way to enclose it in a box.

At first, I was going to use 3/4 inch plywood, but I decided to use 2x4s because that would be easier to make and twice as thick. A few cuts with the circular saw, some screws and some wood glue later, I had a ludicrously thick and heavy box to put my pump in. When I was finished, I realized that I was holding something suspiciously similar to a subwoofer, and in fact, that’s exactly what I had.

Still, I hoped that by being completely enclosed, it wouldn’t let any sound escape.

It did let sound escape.

In fact, I was surprised to find that it didn't significantly reduce the sound much at all, at least to my ear. The higher pitched rattling noise was reduced, but not the deeper hum.

I had read somewhere that sound has trouble traveling through layers of differing material, so I cut up some foam and made a foam box within the wood box and I added foam feet to the bottom. I also tried to enclose it more fully by adding some, uh, spinning claspy things to hold the lid on tight and worked on eliminating any gaps. I used wood filler to fill the seams between members before I realized this was a Bad Idea because it remains somewhat dusty until you paint it, so I had to paint it, which was a pain and would delay deployment until the paint is fully cured but at least I could test it.

Of course, enclosing an air pump fully is a bit of a fool’s errand because of course some air has to enter allow the pump to function. So after painstakingly enclosing the pump, it drilled a couple holes in the box, feeling a bit like fool as I did. I had read somewhere (again) that sound didn’t like making right turns, so I hooked up some air tubes with elbow joints. Surely that would be the key.

The result? The rattling was completely eliminated, but the hum was actually deeper than before. I had in fact made a pretty boss subwoofer, capable of producing a very quiet but very deep hum, the sort that can only be produced by industrial equipment and the subwoofers in my idiot neighbor’s car. Since the hum was quieter, it was somewhat better, but it was also much deeper and filled the room more extensively, so it was somewhat worse. A lot worse really. Also, those air tube elbows didn’t do a damn thing. I had to deem the project a failure.

It wasn’t a total loss though. As I worked on the project, I noticed that I could fit most of my head in the box, so now I have a fully functioning and well-earned Dunce Helmet.

PROJECT STATUS: FAILURE

PROJECT TWO: CANOPY FAN


My canopy was just built a couple weeks ago, and I’ve been waiting for the paint to cure before putting it on (and leaving it on). I finally left it on overnight for the first time a few nights ago, but when I woke up, there was a fine layer of moisture on the underside of the lid. Since it’s made of plywood protected by a few coats of paint, I decided this wouldn’t do. I would have to add a fan.

I think the best option would have been to cut a hole in the lid and put a fan in to send the interior air outward. But I really didn’t want to cut a hole in my lid and add an ugly fan. The pictures don’t really do it justice, but that General Finishes Arm-R-Seal really pops underneath the overhead light, a nice golden sheen (commensurate to its nice golden price), so I didn’t want to corrupt its beauty with a big computer fan.

The back of the canopy is open, but there’s only a 1.5 inch gap between the rim of the tank and the underside of the lid. I thought this would be enough to eliminate excess moisture but here we are. I got a few mini fans for small electronics to place in this gap, but I found that they had a lot of whine, and I questioned whether they would provide enough airflow. So I put them on my returns list (Thanks, Jeff Bezos, hope it doesn’t inconvenience you too much) and bought a larger fan designed to cool AV equipment. Its basically a PC fan with a shroud to move the air perpendicularly to the intake. This one ran quiet and seemed to move plenty of air.

Now came the question of how to attach it to the canopy. After racking my brains (.75 brains still counts as “brains”), I decided to build a little shelf behind the stand and attach it to the wall with those plastic drywall anchors (which I never fully trust, but the fan is very light.) Not an elegant solution, but the shelf is hidden by the canopy.

I added some foam to block nearby airflow and force the air to flow throughout the canopy. It’s only temporary, so I should get to replacing it sometime in the next 5 years. I read a lot of online debates in saltwater forums about whether air should be blown inward or outward, and the consensus seemed to settle on “outward,” but my setup only allows for inward flow.

Nonetheless, I left the setup in place overnight, and found that the lid was nice and dry this morning.

PROJECT STATUS: SUCCESS… SO FAR.

Of course, humidity can mess with wood long before it starts to leave water on its surface, so my verdict on the overall canopy projects is still undecided. Most people build a nice sturdy box, where all the sides act to provide rigidity to each other, rather than have free-floating panels laying on their tanks. It will be a tragedy if this canopy ends up going to hell, but maybe it will add a little excitement to this already thrilling thread. Thanks for reading.
 
In other news, I am back to dosing full EI. I experimented with dosing just P, K, and micros with additional ferrous iron, and I even advised others to consider doing the same, but I'm back to dosing N. I recently upped the light and CO2 in my tank pretty drastically, and at the end of the week before my weekly water change, when I should have max nitrates, my nitrate test was barely distinguishable from my control, distilled water. Some might consider this a success, and I had no problem with plant growth, but I could hear Tom Barr's voice in my head, telling me in plaintive tones, "Dose more! Dose more you fool!" So I'm going to dose KNO3 again since I'd rather stay up at night worrying about nitrates than stay up at night worrying about poor plant growth. What my tank needs now is a little stability after all these changes so I want to have a regime that I can feel confident sticking with for the long term.

The tanks is running really hot right now, high light, high CO2, lots of pearling, lots of growth. I alternate between wanting crazy growth and becoming irritated by the extra maintenance that it entails. I suspect, and I'm sure science will back me up, that BBA has a way of entering the aquarist's brain and convincing them to make drastic changes every few months, just to keep things unbalanced. Or maybe that's the green dust algae.
 
Here is an example of BBA attacking my dwarf sag. You see how the algae-infested plant is surrounded by relatively healthy plants. My interpretation of this is that there is nothing particularly wrong with the general environment; the algae-infested plant is simply old and undergoing senescence. Or possibly the blades were damaged by me rooting around in there. My solution is simply to pull the old plant out, but this is difficult in the case of dwarf sag because they are all connected by runners. Sometimes I just pull out a big handful. Or I snap off individual blades with my thumbnail, but I prefer to get the whole plant out, as well as plants of a similar age. I try to let the plants grow in phased zones so that the plants in a certain area will be of similar ages so I can pull them out by the bunch. This is easier to do in theory than practice.

It's kind of cool how the algae senses the plants weakness and how the healthy plants naturally ward off the algae. This is layman's speculation, but I think if we could understand the signalling that occurs during this process, it would go a long way towards fighting algae.

Perhaps this is all Aquarium Keeping 101, but seeing an unhealthy plant in the midst of healthy plants has underscored a lot of the advice that I have read on forums and shaped my interpretation of how algae works. In short, healthy plants don't get algae and unhealthy plants seem defenseless against it. I don't know if this holds true in the case of low-light plants under high light or in aquariums with lots of dissolved organic waste, but it seems true for the plants I grow in my aquarium. The same thing happens to my monte carlo and rotala. And it's not just BBA, the green spot or dust algae also set up shop on the same plants. They all "know" that the plant is done for. So it seems like algae spends much of its lifecycle floating around in spore form, biding its time, and then it progresses to later life stages when it "finds" a dying plant, knowing that it will have a steady source of food for a while as the plant decays. It doesn't grow willy-nilly like it seems; it is opportunistic. The presence of the algae-free plants nearby indicate that it is not fertilizers or general organic waste in the water column that is causing this process, though they may contribute to it.

The lesson I take from this is that old-fashioned, wet-forearms husbandry is an important part of algae fighting. It's natural to want to tinker with the general water column in such a way that will nuke all the algae in the tank at once. Lord knows I've tried all sorts of potions and fertilizer regimes. But I've never had so much success that I could allow decaying plants to stay in the tank and be algae-free. In my tank, plants are always on the verge of an algae outbreak, and as soon as they show a sign of weakness, they get covered.

The counterargument to all this is that I also get algae on my glass and hardscape, and I'm pretty sure they're not decaying lol. However, they do lack whatever algae-fighting defenses (allelopathy?) that healthy plants have. So the general water column and light levels of course cannot be ignored, and potions such as Excel and APT Fix do come in handy for dealing with hardscape algae. Glass algae gets the scraper.

I'm still on the lookout for an approach that will make my entire tank robustly algae free, hardscape, glass and all, without a lot of trimming and pulling. Some experienced aquarists seem to have reached that level but I have not. For me, an algae-free tank is a tenous state at best.

MORE BBA MUSINGS

IMG_1060.jpg


Here's a picture from when I was doing some serious BBA farming. We tend to take advice on BBA from people who have no BBA in their tanks because that is our desired condition, but I think there's something to be said for examining tanks with lots of BBA. Well, this is one!

You can see I've also got some sort of anemone-esque string(?) algae. I wonder if anybody can identify it. I wish I could have figured out how to cultivate that algae on purpose because I really liked the look of it. It looked like something out of a saltwater tank, although much more drab. It seemed to grow only in the very highest light areas, and when removed from the water, it became a grayish blob of slime. Unfortunately, it had a habit of suddenly detaching itself and ending up as a wad stuck to my intake sponge. The BBA would do the same thing, which is why I ended up getting rid of both. They looked nice, IMO, but were too messy. When I cleaned my filter, the spongers were utterly black - not brown as usual, but black - and they emitted a black water when wrung out. It took forever to wring them clean. I didn't even bother using tank water, and wrung them out with tap water, relying on my biomedia to preserve the biofiltration.

Some say BBA doesn't care about light, but you can see how it tends to grow on the areas that are directly facing the light. They're not necessarily closest to the light, but they are facing the light (a 90 degree angle of incidence, I believe it's called in fancy science terms). These are also the areas with the highest flow, except for the BBA growing on that small ridge behind the stem plants. That area had relatively low flow but a good angle of incidence. Overall, I've come to the conclusion that BBA likes high light and high flow, but that may only be true in the conditions provided by my tanks. It's interesting to me to read that BBA is light/flow agnostic because that is so different from my experience. Perhaps those who hold that opinion are not true BBA farmers like me lol. Here, most of the BBA infested areas were getting extremely high light (the light is perched an inch above the water line), and CO2 was relatively low. I had tuned the CO2 without bothering with a drop checker or pH meter. I just turned it up until I saw good plant growth. When I finally checked it, the drop checker was barely turning a bluish green.

You can also see the phenomenon mentioned in the previous post, where relatively healthy, BBA-free plants are side-by-side with plants that are utterly infested. The key factor in this particular case seems to be age. You can see healthy plants growing out of older, BBA infested plants.

I do wonder what the color of the BBA indicates. It seems to turn a pale teal color when it is truly flourishing, along with a sort of reddish undertone. According to a quick google search, the main light-harvesting compounds in red algae are chlorophyll a, chlorophyll d, and phycoerythrin. If you look at a chart of the light absorbed by chlorophyll a and phycoerythrin, you can see they both hit their minima (you could say "least favorite color") around the teal part of the spectrum and again in the far red. So it seems that BBA has evolved to become teal (i.e. reflect or "reject" teal) rather than green because it is using phycoerythrin, which doesn't hate the green part of the spectrum as much as good old chlorophyll. An ideal BBA growing light might be orange/blue, rather than the red/blue lights used for growing plants. I'm tempted to try to build the ultimate BBA farm using this knowledge.

If you look at the typical spectra of aquarium LEDs, they tend to have a serious dip in the teal part of the spectrum. My understanding is that this is a due to the technical limitations of the lights, and non-aquarium LEDS also tend to have this dip. If we could have more light in this spectrum and a bit less in the blue and red spectra, maybe it would help with BBA. To be honest, this is all above my level of expertise and I'm sure I'm getting a lot of this wrong, but it's interesting to think about.

You can see small sprouts of BBA covering the bottom of the wood piece. They are a deep black, while the big tufts turn gray and greenish. BBA also turns gray and white when it dies, so I wonder if maybe the grayish BBA is not in fact flourishing but simply old. As I said, it had an unfortunate habit of suddenly detaching itself. Huge chunks would come off at once, leaving an area completely clear of BBA. That's how you get rid of BBA by playing the long game lol.

Here's the latest full tank shot. I pulled out a lot of dwarf sag and added some rocks to contain its relentless advance. The Monte Carlo carpet has just about filled in but still needs to reach the corners. I just gave a chop. As usual, I feel that I didn't chop enough.

I've been working on making my rotala more bushy and watched a few videos on how to get that done. Apparently, you are supposed to slide stems in sideways between the bottoms of the upright plants and allow them to wrap their roots around. I've tried this with the plants in the middle, and it looks better already. I trimmed it recently so it's still got a ways to go, but I think it will fill in and get pretty bushy.

You can see the drop checker looking a sickly yellow. I'm still blasting the tank with CO2. I think I'll dial it down once things fill in. The guppies don't seem to mind at all; they're still very much occupied with breeding and feeding. They are rather small, however, compared to the original fish I got from the store. But they were small for a year on low CO2 so I'm not sure what the cause is. Certainly not underfeeding. At least the adults are not underfed. I read that the fry should be feed every two hours and I do not do that.

The shrimp have never liked CO2 as far as I can tell. When I set up this tank but before I had hooked up the CO2, I added shrimp from another CO2-injected tank, and all the shrimp simultaneously molted and became huge and berried. Unfortunately for them, I got the CO2 hooked up on the new tank and they seemed to shrink (or die and become replaced, I suppose) and now they are tiny and I never see any berried ones, but they hang on nonetheless. I assume they are breeding because the population seems steady. For whatever reason, the guppies never bother them with any persistence, though I wonder if they don't stress them out. Hopefully, the shrimp are happy overall. They stay busy munching on algae, so I think they're alright.

My marimo moss as slowly, slowly multiplied. It start with 5 little balls some 6 years ago and now I have I guess twice as much.

Here's a shot of the slate stones that I use for hardscape. If arranged well, I think they create the impression of a single, large, half-buried rock structure, especially when half submerged in a nice carpet. So you can create large rock formations more flexibly and cheaply than buying large rocks. The other benefit of slate is that it is very inert in an aquarium. In the dark ages of the 20th century, old tanks used to have slate bottoms. Can you imagine? I was using "seryiu" stone (in quotes because it was certainly not true seryiu stone) but I found that it was dissolving in my tank. I'd brush it with a toothbrush and a light dust would come off.

Of course, the stones in my tank are not arranged particularly well as you can see. I've never really been able to get my hardscape to shine the way some aquascapers can, even when using large, expensive stones. There's a real art to achieving a harmonious balance and truly natural appearance, an art I haven't mastered. I look at other aquascapes on this site and see that is is a higher level to the hobby that I hope to attain one day. Honestly, all my aquascapes are to some extent the product of resignation. I arrange and rearrange them until my hands are pruny and the tank is cloudy, and eventually I just say "Well, it's an improvement at least" and then give up. I may try drawing an aquascape in a notebook and then trying to recreate it in the tank.

Sigh. Now that I post this picture, I can think of nothing but the algae BBA all over everything, but oh well. I'll be nuking it again soon enough.

I've angled my spraybar upward to create a vigorous rippling at the surface to even out my CO2 levels. It seems to work well. The drop checker goes back to blue by a couple hours after lights off. The aim is to have steep rises and drops in CO2 with steady periods in between, so that a chart of the CO2 levels would have a "crenelated" appearance. The downside of having the spraybar like this is that it causes the light to ripple all over everything, which I find a bit distracting. It's pretty in a way, but it's also a bit like a constant flicker. I'd like to get a submersible light that could avoid this, but I haven't yet found one that seems reliable and powerful enough. I recall that the problem is somewhat improved if you hang your light high over the tank, like a foot or so, but this creates too much light bleed for my taste. That's why I have a canopy, I don't like seeing the aquarium light directly. It's unfortunate that creating a beautiful "natural" appearance in the tank requires so much ugly gear. For a long while, my solution to the flicker problem was to keep the surface flowing but fairly smooth by keeping the spray bar a couple inches below the surface and angled parallel to it. But since I turned the CO2 up, I am more focused on steady CO2 levels to avoid build-up.
