About Time (79 gal, no CO2)

[ElleDee]

Y’all, it's finally here! After years of planning and procrastination, I finally have started my 4ft tank! Every single step has taken way longer than planned, but I think I have done enough now that I can actually start a journal. It’s About Time!

Tank: 120x50x50cm, 79 gallons/300 L Hydra Aquatics Tranquility aquarium

Filtration: Two Eheim 2217s (Classic 600) with prefilters, extra sponges, and a spray bar outlets.

Light: Chihiros WRGB2 90cm suspended - Yes, a 90cm light on a 120cm tank.

Substrate system: mesh bags with a mixed substrate of raised bed mix (pine bark fines, sphagnum moss, with a small amount of compost) + Controsoil + my iron-rich native soil + Safetsorb + a tiny bit of dolomitic lime) with a cap of Caribsea Peace River and Caribsea Tornado Beach decorative sand
I am returning to a DIY substrate with a significant organic fraction. I did something similar with my first two tanks that I'm hoping to improve on, but it’s still fairly experimental. I will post about this mix in detail if I end up happy with how it performs, so fingers crossed.

Concept:
This build is my attempt to scale up and refine what I started with Biding Time. I am really happy with the color and plant diversity in that tank, but I never got the balance quite right. BBA was a persistent issue. I found it difficult to maintain the layout as I had imagined - the aquasoil got everywhere and I found it hard to stop myself from planting in any open area, so it eventually became overfilled with plants. I tried out a lot of stem plants, but once they were happy it was work keeping them a reasonable height in such a short tank. There are worse problems to have, but I want to do some course correction this time around.


Yes, I did do my plant layout by physically making paper placeholders and moving them around.

With this layout I have decided to feature a sunken beach. This will hopefully force me to have one open area in the front for fish and some dedicated sand for future corydoras and/or dwarf cichlids. If the cap migrates onto the sand some it should be much less visually obtrusive than aquasoil. I am planting the front half of the tank mainly with plants that should be kept 6” or less, so there should be a lot of open water above that for fish that prefer mid water and higher. I am still including stem plants, but long term they will be in smaller centralized patches. I mentioned that I have a 90 cm light on the tank and my plan is to take advantage of the gradient of light intensity that will result. Plants that need a lot of light will be in the center, and the periphery will be dimmer. The vast majority of my plants don’t need higher light anyway, even most of the stem plants, and I think it will help with algae management if there is a sizable shady area. I think some fish species will appreciate having lower light areas as well. I also like this from an aesthetic perspective - I think contrasting shadows and bright spots are much more dramatic looking than when everything is uniformly lit like a studio family portrait from the 90s. I’ve gone with a black background, but I hope it is mostly obscured by plants in the long term. I have some amazon swords and taller crypts back there that will hopefully do the job.

I am a fairly patient aquarist, so I expect this tank to take a year to grow in. There will be a lot more stems in the beginning to get that plant mass growing, and the crypts are going to take their time getting established. My light gradient idea will probably take some experimentation to implement properly. There will be other problems I haven’t anticipated (and I’ve already encountered the first one). It should be a fun ride.

I’ve got at least one more post until I’ve caught up with the present and after that we'll have to see what develops.

I love that paper plan

That is what I call a propper planning phase!! So organised @ElleDee !

@ElleDee, Can't wait to see how it evolves.

I've been procrastinating as well for a long time about rebuilding/replanting one of my tanks (150 L). There are just too much to do in real life at the moment, but I hope to get around to it later in the fall before the Minnesota winter sets in so I wont be receiving frozen plants 😉

Cheers,
Michael

I love that paper plan

I really recommend it for anyone having a hard time keeping track of everything. This started as a drawn layout, but it's much harder to move things around and it's more or less to scale. I mean, you could make them to scale, but I didn't want to spend too long on it.

Lol, it only took a few years to get to this point! It originally was imagined as a co2 injected system with a sump. That would have been awesome (and I will run a sump someday!), but I'm confident the current plan is the best I can do at my current skill level (without driving myself insane).

This giant aquarium sat in my small foyer for more than a year. I'm not proud of it, but, yeah, I feel you. Sometimes real life gets in the way.

How close are you to planting? 😊

 

[ElleDee]

How close are you to planting?

Very. I've started prepping plants and am doing a total water change as soon as the kids get to bed. I don't think I'll get it all planted tonight, but I'm going to try to get all the rooted plants in with the water drained, refill, and then suffer through the stem plants tomorrow... probably Friday too, if I'm being honest with myself.

So I flooded the tank on 9/5 and planned to do a dark start of some length. Since I’m using a somewhat experimental substrate, I thought it would be beneficial to let the most labile organic matter break down and give the developing microbiome a head start.

And I immediately ran into trouble. Though the water was initially clear when I flooded the tank, it got murky within a few hours. Some of this is from colloidal clay from the yard dirt, though there are certainly tannins leaching from the wood and there may be some bacteria at play as well. (I don't think bacteria was the initial cause of the cloudiness due to the speed of the onset, but maybe I'm wrong about that. But I wouldn't be surprised if a bacterial bloom happened since then.) Through some combination of time, chemical flocculant, and increased mechanical filtration the situation began to improve after almost 3 weeks. I went on vacation for a few days last week and came back to an almost entirely clear tank. I thought, ok, that’s enough dark start for me.

I immediately began preparing to plant.

Here’s a better shot of that layout for the curious:


There is a strong emphasis on rosette and bulb plants, particularly crypts. This is no surprise of course - I’ve made no secret about my love of cryptocorynes. I’m actually very excited to see my background plants grow in. Coming from tanks that are 12 or 13” tall, growing something to the top here is very novel.

For the first time ever, I have no brand new plants going straight from my mailbox to the tank! The Cryptocoryne usteriana, C. spiralis ‘Red’, and some of the C. lucens are TC plants I've only been growing out for a month, so while they look quite happy, they are still quite small. A few of the others are also fairly new, but seem to have acclimated easily. New plants always do much better in a mature tank, and hopefully they will benefit from the strong start and be able to transition over to the new tank without too much trouble.

On Monday I broke down the nano shrimp tank in the kitchen. It was the second tank I built and the first I have ever taken down. Between the dirt substrate, the wall-to-wall crypts, and all the shrimp it was quite a pain to deal with! I found out I have a mild skin sensitivity to crypts, so the next time I have to rip through a pound of them I should wear gloves. A quick Google search tells me I'm not the first person to experience this. Good to know, I guess.


A small handful of the crypts from the nano tank

I wanted to add some of the bacteria and microfauna to the new tank, so I rinsed out the cap as much as possible and added it to the new tank. It’s mostly the same Peace River sand/gravel, but it’s got some larger stones mixed in as well, plus the small amount of dirt that remained. You may be surprised to hear that after so many years there were still discernible bits of pine bark left in the substrate. Probably lots of microbial goodies in that pine bark, not that I could have washed it all out anyway. And I siphoned out some little seed shrimp or whatever they are and added those directly. I don’t know that the tank is stable enough for them to survive, but why not try?

After rinsing it out, I immediately turned the nano into a holding tank for all the cleaned and sorted plants, (plus a large ‘Narrow K’ java fern from another tank).

Yesterday I harvested a good chunk of the stem plants out of Biding Time and started moving fish and shrimp into other tanks.

Tonight the tank gets drained and planting begins!

 

[ElleDee]

First, a moment of silence for Biding Time, as it has been consumed by this build. It began as a side project to try out some new ideas while I waited on this tank, so it's a fitting ending. It had a good run.



Whew, that was a lot of work! Planting went pretty smoothly, but it has still taken me two days off and on. I’m very glad I had the layout worked out ahead of time - there’s no way I could have dont it on the fly at this scale. I did deviate from the plan in a few spots, but on the whole I executed it as I had imagined. And seeing it in real life, I quite like it! So far, so good. (Actually, I suspect I have too many big/tall plants, but we’ll see how it all grows in.) And no cloudy water!

Now’s the hard part - waiting to see if the plants hit the ground running or start to melt. Going forward, I plan to do two water changes weekly for a while and monitor for emerging problems.

I still need to hang the real light, so for the moment I’ve got this temporary one that should be giving me about 100 PAR directly beneath it. Good enough. Unfortunately it makes the colors look very washed out, but once I have the real light I’ll break out the good camera - until then it’s going to be cell phone pictures.

 

[ElleDee]

Just a quick update as there’s not too much going on. The most important thing is most plants in the new tank have put on new growth. I’m happy to see it; it's the first sign that things are going well. The stem plants have immediately adjusted their form to match the lower lighting - red and reddish leaves are greener and in some plants the internodes have lengthened. I appreciate having a visual marker of where the growth in this tank began, because iIf the old growth deteriorates or becomes algae infested it just needs to be removed, but struggling new growth is a warning sign that there's A Problem. The race is on now between the adapting plants + maturing microbiome and the algae that hasn’t arrived yet.


Other than water changes on the big tank, my focus this week has been dealing with all the extra plants I ended up with when I broke down my other aquariums. I greatly underestimated the volume of plants I had packed into my kitchen nano and Biding Time and I had to sort out what I want to keep, what should be tossed, and what can be auctioned off at my local club this weekend. And then everything I was keeping had to be planted somewhere, so I had to clear space and rearrange my existing tanks. It's been a big game of Freecell, but I think I'm finally seeing the light at the end of the tunnel. I've dealt with all the containers of water sitting around anyway. I need to hang the Chihiros, but I don’t plan to approach the PAR I had in Biding Time until everything is more settled anyway.

I have my all livestock in just two tanks now - my best colored shrimp are in the nano I set up in April, and everybody else in my OG 20 long. Honestly, the fish seem happy to be back together even though there are groups of three different species. At any rate, there’s a lot of hustle and bustle and males displaying to each other, etc. It’s nice, especially when some of these fish are pretty geriatric.

I’m not totally decided how I’m stocking the big tank yet. I’ve stuck with light fish loads historically, but with the bigger tank I want a lot more fish. That was the primary reason to get the tank to begin with. I go back and forth between wanting a group of Bolivian rams as my big fish, a group of congo tetra, or to skip the larger fish and get bigger schools of smaller fish. It will probably come down to what is available when I’m ready to pull the trigger. I always quarantine new fish for a few weeks, so honestly I could probably get fish now and by the time they were done with the QT the new tank would be more than ready for fish. Hmm…

 

[ElleDee]

So I went to my local fish society’s auction to sell all my extra plants. I had no expectations going into it, but I put together lots that I would buy myself and hoped for the best. The auctioneer was a plant guy did a good job marketing to the crowd and in the end everything did pretty well! It turns out big hunks of unique java ferns are pretty popular. It was very validating to see other people pay good money for plants I spent years caring for. And it's kind of wild for the hobby to actually bring in money instead of the other way around.

I also made a few purchases myself. I have never participated in a live auction before and I felt like I was in a psychology experiment. My modus operandi is always “over prepare in advance, and then make impulsive changes to the plan when executing” and, yeah, that's basically what happened. I stuck to my personal limits on bidding (yay, good job, me), but I walked out with some unexpected fish.


Six Melanotaenia sp. "Kali Tawa" juveniles! The paddle moved me and I got them for a steal! I think they might all be males? That would be fine with me - I don’t want to breed them and I want maximum color. I’m so excited! At one point I had seriously considered putting some full sized rainbowfish in this tank and ultimately decided they were just too big, but these guys max out between 2.5 and 3 inches. They are in a quarantine tank for the next few weeks and then they get to try out the big tank. I've got some brine shrimp eggs in the hatchery that will be ready for them in a day.

 

[FrozenShivers]

Tank is looking great so far, well done! Currently in the planning phase of one with the exact dimensions as yours. I need to try an auction one day too.

Selfishly I hope you add a group of bolivian rams, I've always fancied a group of those and I'd love to see how they act in a group in a lovely planted tank like this. They aren't super colourful, but those faces are SO cute and clearly very intelligent!

I was leaning that way, but I'm not sure I could make them work with the rainbows now.

That said, there's something up with these rainbows that I don't like. They are stressed at a minimum and hopefully that's it, but I tend to be pessimistic about these things. I'm doing what I can to help them, so we'll see if they start acting normal or get worse. They are in quarantine at least, so should the worst happen (ugh) I can bleach everything and start again, and in that case I think rams are going to be top of mind.

Getting new fish is not always everything it's cracked up to be. 😭

 

[Courtneybst]

I love the planting placeholders!

I also recently got some Kali Tawa rainbow juveniles, they'd been on my list for a while.

When you say they're stressed, in what way?
