From Reef to Planted

[andyseatrout]

Hi, I'm new to the forum and about to embark on a large planted aquarium.

I have been running a reef tank for the last three years and have decided to close this down and make the switch to a planted tank, primarily due to the cost of running 3 x 250W halides. I would like a fairly heavily planted tank with some clear space to give the feeling of depth and I have decided to use this tank as inspiration:

http://www.bubblesaquarium.com/Aquascap ... Tank08.htm

The tank itself is 160 x 60 x 55cm with two rear overflows and I am going to continue to run a sump which is 132 x 38 x 41cm. Accounting for displacement, I will have approx 580 litres or 127 gallons of water. The equipment that I will continue to use is as follows:

Eheim compact 5000 - as a return pump, fed through two jacuzzi style nozzles towards the top RHS
Tunze 6080 powerhead (8500 lph), Tunze 6045 (4500 lph) and possibly a Koralia 2 (2300lph) for flow
A phosphate reactor to run carbon, if needed
ATC 800 to control heating and cooling (with 1 heater and several fans)
150W envirolight lamp with reflector to reverse light a section of the sump to keep up O2 levels at night.
I also have an independent 4 pump dosing unit that I could use to dose fertilisers as and when the need arises.

For lighting, I have just purchased an ATI sunpower unit which will run either 4 or 6 80W T5's, depending on how many I need to run. In any event, I plan to have part of the photoperiod running with 2 tubes and part running with either 4 or all 6. I plan to use ADA Amazonia as the substrate with RO/DI water.

I have also purchased a TMC regulator with solenoid valve to enable me to run CO2 from a FE.

I am still in the process of selling my marine livestock, so I can then shut down and clean the tank and equipment. I am still at the planning stage, so open to any suggestions to change and/or improve my plans.

Currently, I am a bit stuck with the idea of CO2. Initially I thought that I would be able to simply run an UP aqua inline diffuser (http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWAX:IT) on the outlet of my return pump and just get away with that, but,

a) it won't fit onto the 19/27mm tube
b) I don't want CO2 bubbles being visible in the tank

If I am going to use this pump to drive the CO2 I think I will have to use a reactor, so I am please looking for advice about which one to use and where to get one from.

I also like the look of this bubble counter and wondered if anyone had any feedback on it? (http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWAX:IT)

Please could someone also tell me the best CO2 to use and where to get it from? I am based in Southampton.

Finally, I would like this set up to be as low maintenance as possible and keep the start up costs down. If I use the ADA Amazonia, would I really benefit from using the power sand as well, or would I still get good results using the aquasoil on its own?

Looking forward to hearing from you and thanks in advance for your advice.

Hi and welcome to the forum.

First off, decide what you want from the tank and how much effort you are willing to put in.

To me a low maintenance tank is one that can be left for several weeks with just fish feeding going on and a water change every month or so. If that's what you are after, then you could probably forget most of what you've suggested. Keep the lighting low i.e. no more than two bulbs and you can forget CO2, ADA soil, and fertilisers. Just use 2mm gravel and some easy to grow plants

If you want to use more light then you'll almost certainly have to go down the co2, fertiliser, regular water change route, which isn't exactly difficult but does require more effort, esp doing a weekly 50% water change on a tank that size.

As a last note, if you do use co2 I would considered not using the sump as you'll probably find you waste quite a lot of co2. That said I guess, on a tank this size you'll want a large co2 cylinder anyway, one of the pub type ones, which'll last a while anyway so it may not be a major issue.

It'll be an evolving process, but hopefully that gives you something to start with.

Hi Sam, thanks for your input.

It is the water changes that are my main worry. I do have a 48 x 15 x 18" tank that I can use to preheat water and I can pump it directly from there to the main aquarium, but that would be my maximum easily available water change (212 litres = approx. 36% ). Is this something that I could "get away with" if I carried this out as a weekly water change?

I would like to keep the sump to keep the other equipment out of the tank and use it as a filter with sintered glass and an area for some fast growing plants, although I do realise that I will be loosing some CO2 by doing this. It will also reduce the cost of setting up as I will not have to invest in a very expensive external filter.

I am aiming for a well planted tank where I can grow whatever I want to and stock fairly heavily with a mixed community. If I can achieve this using the resources I have available along with the equipment I am planning on purchasing, I will carry on with the planning and purchasing, otherwise I will have to have a rethink .....

Hi,
Firstly, your water changes can be made a lot simpler if you just forget about using RO water, which is completely unnecessary and actually counterproductive in a planted tank. That way, you are not limited to just what you can fit in an auxiliary tank but can pull water straight from tap. Unless you have special fish requirements or unless your tap supply is high in some unusual toxin it is pointless to be so dedicated to RO. You can even use a combination of RO+Tap ifyou do have special fish requirements.

Secondly, you would do well to study the thread My venture into my new 760 ltr aquarium which is a pretty good account showing how the OP tackled the issues of dealing with using a sump.

Thirdly, a highly lit CO2 enriched tank cannot also be a low maintenance tank. These are mutually exclusive concepts, however the maintenance requirement of an enriched tank can be ameliorated somewhat by minimizing both the spectral energy as well as the level of CO2 enrichment. The fact that you have such excellent flow potential in the sump gives you the ability to use lees light/CO2 and to maximize the distribution of the gas while minimizing the injection rate. As discussed in that thread link above though, you must solve the problems presented by almost all sumps by minimizing the CO2 loss in the sump. Once you achieve that and once you have a good distribution technique you can then lower the injection rate and still have good growth performance.

I see no reason whatsoever, that given the incredibly potent set of equipment you listed above, that you cannot achieve at least some of your objectives.

I have no idea what "150W envirolight lamp with reflector to reverse light a section of the sump to keep up O2 levels at night." means as I'm not familiar with reef technology but pending further clarification I'd say this does not sound good. Can you clarify the basics of this technology?

Again, 6 80W T5 bulbs would result in such incredible spectral energy input that you would need mammoth levels of CO2 and the maintenance requirements would be debilitating.

ADA Amazonia is an excellent substrate choice, but is very expensive. There are plenty of low cost ways. No need to spend the amount of money necessary for all those soil supplements.

There is no "best CO2". CO2 is CO2 so pub cylinders, B.O.C., wherever you can find it is all good.

Cheers,

I can see where you are coming from being a reef keeper myself, I love all the filters, reactors & everything high tec that goes with reef tanks LOL.
However you dont need to be so technical with a freshwater tank, its really quite basic in comparison. You do need to get the balance right though - thorougher Co2 distribution around the tank is really important as is adequate fertilization matched to your lighting level.
Basically three aspects to get right & you will see your plants thriving, of course making your tank look like a living picture is not so easy!
I use sumps on my tanks & as has been pointed out, they do require more gas unless you really want to be more tec about not losing it?
Co2 is relatively cheap - sumps are great - at least that is my opinion but, to be honest definitely not necessary.
I have a semi automatic water changing arrangement on my plant tank that removes about 50% of the tank water & tops back up straight from the mains supply via a dechlorinator. Again not necessary but, fun!

Living in Southampton we have very hard water with high levels of both phosphates and nitrates. Although I realise that the phosphates and nitrates would be used by the plants and I would be stripping out what I would then be replacing, to my mind at least I would be dosing a measured and more importantly steady quantity if I used RO water.

Secondly, you would do well to study the thread My venture into my new 760 ltr aquarium which is a pretty good account showing how the OP tackled the issues of dealing with the issues arising when using a sump.

What a read and what a tank - shame not all the pictures were available. The loss of CO2 via the sump, more specifically the overflows has been something that I have thought about. Having twin standpipes controlled with valves, I can ensure that no air gets dragged down one pipe and only a little gets dragged down the other. I have previously managed to get both with no air and I am confident that I will be able to do the same in the future. I will however think about how I can seal the sump and fit coverglass over the tank as I will initially be relying on a 2kg fire extinguisher as my CO2 supply!

Thirdly, a highly lit CO2 enriched tank cannot also be a low maintenance tank. These are mutually exclusive concepts, however the maintenance requirement of an enriched tank can be ameliorated somewhat by minimizing both the spectral energy as well as the level of CO2 enrichment.

As discussed in that thread link above though, you must solve the problems presented by almost all sumps by minimizing the CO2 loss in the sump. Once you achieve that and once you have a good distribution technique you can then lower the injection rate and still have good growth performance.

I have just found out about the Dannerle Cyclo Turbo Diffusor which is expandable and even with the expansion kit and pump to power it is still cheaper than the Aqua Medic 1000 and I am hoping will provide me with my initial CO2 saturated water.

I see no reason whatsoever, that given the incredibly potent set of equipment you listed above, that you cannot achieve at least some of your objectives.

I have no idea what "150W envirolight lamp with reflector to reverse light a section of the sump to keep up O2 levels at night." means as I'm not familiar with reef technology but pending further clarification I'd say this does not sound good. Can you clarify the basics of this technology?

Currently I am running this lamp at night when the main tank lights are off in order to reduce pH swings. The idea is that the plants growing in the sump will absorb some of the CO2 being produced by the tank inhabitants and bacteria which would otherwise during the day be absorbed by photosynthetic algae. These plants also act as a form of nutrient export and provide a habitat for shrimp etc. to breed which then occasionally pass into the main tank as a food source.

I just thought that this might be a good practice to carry over to a planted tank for the same reasons, including nutrient export.

Again, 6 80W T5 bulbs would result in such incredible spectral energy input that you would need mammoth levels of CO2 and the maintenance requirements would be debilitating.

I would most likely only run 4 tubes at any one time. I would have two come on to start with, followed by a switch to four for the main photoperiod, phasing back to two again for the end of the photoperiod. I am hoping that this would have a less shocking effect on the fish.

All truth told, I was going to buy a 4 tube unit and only when I spoke to my supplier about it did he point out how narrow this unit was. He had another customer that recently bought a 6 tube unit, realised it was too narrow for his needs and wanted an 8 tube unit. This then provided me with the opportunity to get a 6 tube unit with a better spread of light for the same price as a 4 bulb unit, so I went for it!

ADA Amazonia is an excellent substrate choice, but is very expensive. There are plenty of low cost ways. No need to spend the amount of money necessary for all those soil supplements.

The price is really putting me off as well, but from what I have read this is the best stuff, especially if I decide I don't want to go down the EI route, which I am really unsure about due to the massive water changes involved. I would only be using the Amazonia and not any power sand or other additions, but I would hope that I could rely on this alone (along with lighting, CO2 and flow) to start me off.

There is no "best CO2". CO2 is CO2 so pub cylinders, B.O.C., wherever you can find it is all good.

The tank is in our lounge with no suitable adjoining room for storing a large CO2 cylinder, so the only suitable place is in the cabinet. I can easily fit a 2kg FE under there, so I am hoping that I can get a 5kg FE in there instead. If I go through that too quickly, I will have to think about other options, byt I do have a couple of friendly pub landlords that might be able to help!

What size tanks are you running, how much CO2 are you getting through and what size cylinders are you using? I am assuming (maybe incorrectly!) that you have a dedicated fish room?

Please could you provide more detail about your semi automatic water change system?

 

[foxfish]

No fish room, I am semi retired now but, I used to build, install & maintain aquariums.

Your tank is not that big as to use up 2k of gas in less that 6 weeks. However that is a guess as it depends on so many variants.
I would look into an in line C02 diffuser as they are very efficient & cheap at around £20!

Re the sump, one way is to recirculate the sump water in the day time (gas on) with only a slow flow through the display tank. Then up the flow at night (gas off) to cleanse the main tank. This is best done with two pumps.

Think very hard about flow within the tank display, imagine it full of plants & see how you are going to spread the gas enriched water evenly.

Thanks for your feedback, that's great to know. I was looking at the UP atomiser connected to my return pump (eheim compact 5000). The return plumbing is split into two and the pipe run equates to about 2m. I was hoping that this would be sufficient to dissolve all of the CO2 before it reached the tank, but I am having second thoughts as

a) I don't want CO2 bubbles racing round the tank;
b) the diameter of the pipe I am using is 19/27 and the UP atomiser only takes 16/22 and I don't really want to restrict the flow from the return pump.

However, if you think that this pipe run anlong with the injection rate that I will have to use will be sufficient to dissolve the CO2 before it reaches the tank, this would definately be a way forward.

Re the sump, one way is to recirculate the sump water in the day time (gas on) with only a slow flow through the display tank. Then up the flow at night (gas off) to cleanse the main tank. This is best done with two pumps.

I am guessing the reasoning behind this is to reduce the loss of CO2 through the use of the sump? I suppose I could change my plumbing arrangement so that I have a lower powered pump returning CO2 saturated water to the main tank through one of the jacuzzi fittings and the eheim 5000 returning through the other. This however would give me much less of a spread of CO2 saturated water, unless I was able to fit a spray bar to one of these fittings, which I don't know is possible?

Think very hard about flow within the tank display, imagine it full of plants & see how you are going to spread the gas enriched water evenly.

With the current arrangement I have, I am very confident that I can easily spread the CO2 enriched water all the way around the tank, but I would be less so if I put the returning water through just one fitting.

 

[foxfish]

I can see you are keen to use all your existing marine set up but, to be honest you would probably get better results by fitting two external canisters & not utilising the sump.

You only have look around this forum to see that the most amazing displays are very basic in there design.

I do use a sump but, it was built & designed around a plant tank. I only run a small pump to circulate the sump & tank.
I use an independent pupm to feed & recirculate the C02 via a in line diffuser avoiding the sump completely. My planted tank is drilled each end, I draw water from one end pass it through an eheim 1060 & back to the other end via the diffuser. This is an independent C02 circuit from the sump.

The sump is a basic acrylic tank that contains a bag of bio balls a heater & a power head, the water from the tank flows over some floss - nothing else.

The benefit is a clutter free display good bio action & easy to clear mechanical filtering, plus a clean surface in the display & a permanent water level in the display.
My marine sumps are very different, they are designed to have a high flow rate & mulible compartments, reactors, trickle filter etc.

 

[andyseatrout]

Some of the reasons that I would like to continue to use my sump are the same as yours; easy maintenance, constant water level and clutter free tank (apart from powerheads). Other reasons are that I might want to return to marine in the future and I don't want to redo all the plumbing I have already completed, I also have limited funds, so didn't want to invest in external filters or have the hassle of maintaining them.

If I were to use external filters on just the tank (460 litres) what would you recommend? I do have a Fluval 304 and an Eheim 2213 available, but I would be reluctant to use either of these.

Living in Southampton we have very hard water with high levels of both phosphates and nitrates. Although I realise that the phosphates and nitrates would be used by the plants and I would be stripping out what I would then be replacing, to my mind at least I would be dosing a measured and more importantly steady quantity if I used RO water.

Hello,
Hard water or soft water has little relevance to the vast majority of the plants available to us. In fact, most of the plants actually do better in hard water. Regardless of the water content, you must still dose a measured quantity of nutrients into the water column. Using tap is such an easy solution to your problem of water changes. You will only be handcuffing yourself unnecessarily by worrying about something that absolutely doesn't matter.

Southampton water is no worse than Horsham water as regards hardness and yet I had no difficulty whatsoever growing some of the touchiest plants when I lived in Horsham. I even added more hardness to the water just to see where the hardness limitations were. I did not find a limit. I can think of only a handful of plants that do better in soft water and none of those plants are on the list shown on your sample webpage.

Here is a 150 gallon tan on water change day. I just hook up the yellow garden hose, turn the spigot counterclockwise and sip on my Sunday morning coffee while waiting for it to fill. No stress.

At the end of the day the tank in repose. KH greater than 15, GH greater than 25, conductivity greater than 800 μS/cm. People really need to get over RO. The goal in a high tech planted tank is to achieve excellent CO2, after which all other issues become completely irrelevant.

Currently I am running this lamp at night when the main tank lights are off in order to reduce pH swings. The idea is that the plants growing in the sump will absorb some of the CO2 being produced by the tank inhabitants and bacteria which would otherwise during the day be absorbed by photosynthetic algae. These plants also act as a form of nutrient export and provide a habitat for shrimp etc. to breed which then occasionally pass into the main tank as a food source.

I just thought that this might be a good practice to carry over to a planted tank for the same reasons, including nutrient export.

As foxfish mentions, this is not at all a common practice in freshwater systems and adds complications. Ph swings due to CO2 is not a concern. If the sump lighting is too high for the plants that you have in the sump for the available level of overnight CO2 then this results in algal blooms. If you get it right then it's a brilliant idea, but if it goes wrong then there's no end to your troubles. I would wait a while before trying this.

If you're having difficulty finding a location for a CO2 cylinder, remember that it is not important that the cylinder be located near the tank. You can store the cylinder remotely and use your imagination to run the tubing to the tank. The only penalty is that the volume of air in the tubing causes a longer delay for the gas to get into the tank in the morning but this is not a big deal.

Cheers,

Lovery pictures Ceg - Andy you dont need expensive substrate either, all these soils are great & very much in vogue but, you can use sand, gravel, bonsai potting media, cat litter or conurbations of all of them!
I have been experimenting on growing plants without any media & that works too LOL.

 

[Always Broke]

Thanks for reading my 760 ltr tank adventure. Note sure why you could not see all the Pictures as they all seam there now.
Nearly 12 months on and here are my views on what I have learnt about equipment
My Auto water change system is the best thing ever. 50 % on Thursday and again on Sunday straight from the house water supply. I have done away with the pre filters but it is still pre heated for the fish. It still works as good as the day I made it and is 100% reliable. That along with the home brew water top up is my time saver. Most weeks I spend less the 10 mins on the tank , which is perfect for me at the moment. One other thing is don't but cheap timers , spend a bit more and they become super reliable.

My Sump. I have changed some of the media. I now still have the prefilter sponges which get a trip in the washing MC once a month, then sintered glass , loads of bio balls , No silly fine sponge type stuff that needs looking after all the time. The prefilter sponges are going to get changed for more bio balls.
The return pump is still a Aquamax 10,000 and is running faultless. It has good fitting cover glasses fitted on the sump now.
I still inject my co2 through a ceramic stone into the inlet of an Aquamax 5000 feeding the 10,000 on a "T" but this will be changed after Xmas. It has worked but is very crude and I think wasteful. Watch this space.
I would not dream of not running a sump for just for maintenance time saving and somewhere to put all the junk.
Just seal it up.

The main tank also has cover glass fitted to 95% of the tank to keep the condensation down in the room its in.

Don,t mess with silly Gas bottles. Go get the biggest you can get. My one is 45Kg. Put it outside where you can find a space and run the pipe and solenoid power to it. I use 6mm rigid plastic tubing and run it under the floor in the house.
Put a bucket over the top of the bottle and Regulator. I sprayed it all with spay grease as well.
Dosing Ferts and Trace. I use two dosing pumps on timers.Works perfectly . I mix up 10 ltrs of each . Just refile when empty which takes 5 mins if you buy spoons that measure your mixes in one heap. Just mix with tap water.

All my fish are fine and my plants. I will change a fair few of them soon , but thats just because I fancy it.

Can't wait to see some pictures.

[andyseatrout]

Ok guys, you have all given me lots to think about and thanks for that because this is exactly why I posted here in the first place. You have nearly persuaded me to go tapwater, low cost substrate and sort out a proper water changing system (which is what I should have done a long time ago!)

Ceg - They are great pictures of a beautiful tank, is that one that you are currenty running? I take it that you at least pre heat your water before you do a water change? Do you treat it with anything to remove the chlorine as well?

You appear to be running at a very high KH - what is the benefit of this? I have been lead to believe that it is far easier to load water with CO2 at a lower KH and this would be a benefit provided by RO water; is this not the case?

If I could just dump a hose in and fill with tapwater for each water change, my life would become far less stressful!

Foxfish - If I can sort out a more suitable way of water changing on a regular basis without my other half throwing me out of my own house, I would gladly part with less cash and use a cheap substrate without the need to rely on the nutrients that would be contained within a substrate like Amazonia. It is clearly the water change issue that I need to get around.

Simon - I must congratulate you on an excellent build. Your craftsmanship is superb and you must be very pleased with what you have achieved. Thanks for taking the time to provide me with some of the knowledge you have built up along the way. If you ever want to come around and help me make a water change system like yours, you would be very welcome!

OK - I could store a large bottle of CO2 outside, or maybe under the stairs, or in the conservatory.

I could also maybe set up something underneath the house or in the loft to assist with water changes.

All ideas would be welcomed please!

How do you get your hot water at your Taps.??

How do you get your hot water at your Taps.??

Well if I take that question at face value I would say that the cold water is fed via a rising main downstairs and upstairs it is fed via the cold water tank; the hot water is gravity fed both upstairs and downstairs, but I don't think you meant it that way ......

I do not have the luxury of a combi boiler, nor the funds to obtain one especially just for my hobby and I cannot rely on the hot water downstairs as the pressure constantly falls away at the kitchen tap.

I do however have a pumped shower that I installed upstairs and it is possible that I could tee off from that to provide hot water. If I am going to make either a fully or semi automated water change system, I would want to do it properly and although I plumbed in the shower upstairs, I would have no idea where to start with this, so I am genuinely asking for help.

I could easily install something in the loft that would be easily accessible or I could do something that was far less accessible underneath the house as the floor is suspended. I had to reinforce the floor to put the tank there in the first place. As an absolute last resort, I could do something in the garage, but that is at the bottom of the garden and has neither water nor electricity.

 

[andyseatrout]

OK, have just read the DIY water change, no more buckets thread and now feel a little more in the picture!

I would however still like to set up a permanent fully automated water changer ......

 

[ceg4048]

Ceg - They are great pictures of a beautiful tank, is that one that you are currenty running? I take it that you at least pre heat your water before you do a water change? Do you treat it with anything to remove the chlorine as well?

Thanks very much. The tank was torn down not long after the shot was taken. I still have the tank but I've moved around so much since I got to Florida I haven't been able to set it up, especially since the gear is all 220V/50Hz. I didn't do any pre-heating and I didn't add any dechlorinator (but I wouldn't recommend that unilaterally because everyones tap is different and I was just lucky in that regard.)

In addition to the cold water coming from the outside spigot I would also run a line from a Eheim submersible pump in the nearest bathtub filled with water from the hot water tap. In the winter I would forgo the garden hose and just fill the tub with hot + cold. It was slower but that just gave me more time to read the comics section of the newspaper.

You appear to be running at a very high KH - what is the benefit of this?

No benefit at all. Whatever came out of the tap I used without issues and without obsessing over the water chemistry. I only obsess over the following:
CO2 injection.
Flow and distribution.
Cleanliness of the tank and elimination of organic waste.

I have been lead to believe that it is far easier to load water with CO2 at a lower KH and this would be a benefit provided by RO water; is this not the case?

No mate, it's not the case at all. That is just an illusion that people choose to believe for various reasons. The solubility of a gas in water is strictly a function of the water's temperature and the partial pressure of the gas. Since we inject CO2 at a pressure above atmospheric via the regulator, the gas dissolves in the liquid the same amount regardless of the presence of any other solute in the water. Check these threads==> Problem with Riccia
and Stupidly used oyster shell gravel..

If I could just dump a hose in and fill with tapwater for each water change, my life would become far less stressful!

I do not add any Dechlorinator to my water change water.Never have done.
So get along to your local plumbing centre and get one of those over the sink water heaters for washing your hands.
Mount that in the cupboard under the tank and plumb the outlet to the tank. Set the temperature of the outlet to your tank Temp. Dose not come any simpler than that . Warm water change water sorted.It dose not mater if its a couple of degrees different . Get out of marine mindset.

Or run both hot and colt from your domestic system to the cabinet . Fit a mixer tap again with the outlet run to the tank.
On the mixed water outlet put a washing MC solenoid valve (about a fiver from ebay) connected to a switch for manual control. You could do as I have done and use a float switch in your sump to operate it. How simple is that. No more hoses, stored water or any of that rubbish and so simple to do.
