DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
This system seems to have come about from pond filtration where it is not feasible to change thousands of gallons of water but the pond still needs clean water for koi fish.
It has been adapted for aquariums as well and is supposed to eliminate nitrates, phosphates and other items. Has anyone tried this DIY filter?
I would really like to try it but don't have the space in my sump right now because it is full of an algae scrubber. Maybe on my next aquarium build I could add space...

If this is the first you've heard of this, keep going past the kitty litter and it is very interesting! LOL
Dr. Kevin Novak has a ton of videos about it on YouTube with a Discus aquarium (which he calls "disc" instead of discus which seems really funny to me).

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
funny you ask ...just back from town and grabbed a bag of kitty litter , it has only clay , the size of the granules looks fine . it was not that easy to find !
there's everything out there , grass , paper , lots of clumping , organic and gluten free ! Next step will be testing the granules to see if they dissolve .
if they don't , I'm thinking about setting up an anoxic basket in a small test tank and see how it evolve in regard of ammonia , nitrite , nitrate , ph
using household ammonia as in the start of a fishes cycle ...safety first , the gang is happy and I don't want to mess with that

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
The process to eliminate nitrate is scientifically described as denitrification. You can get the detailed chemistry via Wikipedia. There's no harm trying, although I want to point out two caveats:
1. Koi are far more tolerant of nitrate than discus, > 15 ppm
2. Denitrification is a reduction reaction, which occurs far slower than an oxidation reaction (which is what happens during biological cycling NH3 -> NO2 -> NO3).
What ever happens, I wouldn't recommend this as an alternative to doing water changes in a discus tank. It might work with Africans.
Good luck, Willie

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
But if you have an algae scrubber why do you need a de-nitrificator as basically the two do the same job? Also de-nitrification is a fiddly process that can go awry. I use scrubbers in my mbuna tanks and they do the job but, as said above, discus are more demanding for pristine water quality (not just in regard to nitrates and phosphates but also organics and microbial population that scrubbers/de-nitrifiers do not address) so I do daily water changes.

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
You guys should read about this anoxic method. BAsically there is no "nitrification" the way we know it. There is no oxigen and no KH consumed during the process. It is a very interesting and opening mind read.
Please do, you all will be wanting to build one of those short after.

What type of clay only kitty litter are you going to try?
I've seen the this recommended kitty litter on Amazon but heard somebody say they stopped baking it so it doesn't dissolve in water...

Don't get me wrong, I love my algae scrubber. I think it's absolutely amazing but it's not perfect. This could be a supplement to keep even better water and possibly reduce the quantity of needed water changes even further while keeping healthier discus. I agree with others though that this would aid to "reduce" the quantity of water changes not eliminate. How much reduction would be different for each tank and the filter's effectiveness.

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
I haven't got time to read the whole article or watched all of their videos but I think they are referring to a kitty liter made of "Diatomaceous earth " . Its a baked clay product with similar properties to L.E.C.A products or laterite.
Planted tank enthusiasts and Bonsai hobbysts use the diatomaceous earth clayballs and reffer it as Kittydama (name for a cheap alternative of the expensive Akadama soil ).
I have watched a video of a sump filled with baskets of kitty liter and a pump underneath them to push water through the baskets .
I just don't understand how an oxygen depleted area can be achieved with a material as porous as the kitty liter and a pump pushing water and aerating on top of it ?
If the main purpose is to create an anoxic area , area without any oxigen in it , shouldn't be more appropriate if we just use a deep sand bed ?
This sump on the video seems to me like any other sump filter , but just filled with kitty liter instead of other bio filtration materials.

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
I switched my sump over to an Anoxic filter with 3 BCB's. Its been up an running almost 4 weeks (Nov 12th to be exact) Nitrates in tank 5ppm at any given time. Tank is 90g and sump is 30g.
I have 6 Discus now that are between 4 and 6" apart from a stunt
Things I will point out, Discus have increased activity and are more lively, any algae that did appear in the tank is very quickly now in retreat, especially plant algae.
Water clarity is amazing.
Nearly all my previous biomedia has been removed apart from a few blue bioballs and a small bag of matrix, thats almost 90% less of what was in there before the BCB's
There is no carbon, and I have taken out all the purigen as well.
The tank has never looked better and there is still 3 to 4 weeks still to go before the system has completely kicked in.

Thanks for sharing. What were your nitrates before the BCB baskets?
Please let us know how it progresses!

The BCB requires laterite and clay baked cat litter.
Also note, its Anoxic NOT Anaerobic,,, 2 different things completely
Being an ION filter as well and the "special" bacteria we are trying to produce is a Facultive heterotroph, this is what makes the magic happen.

Nitrates never got above 5ppm over a week as I was doing 50% w/c's EVERY day. Since the BCB's have been in I now only do 50% every second day. The test will be in another 3 or 4 weeks when I see what happens with the nitrate readings after w/c every 3 days then 4 and so on. I aiming for 1 to 2 ppm with a w/c one a week or even every second week.

Is there any reason why a person couldn't use kitty litter in a media bag placed in a canister filter?
Would that be effective?

Two things, kitty litter alone doesn't constitute a BCB, you need Laterite in the middle of it. Secondly, the system doesn't work with high flow and in a canister, how do you stop all the muck and filth entering the basket?. Canisters are nothing but nitrate producing filth machines and IMO are not good for a discus setup. Sump is the only way to go, especially if you decide to use BCB's

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
Hi everyone . it took a while to gather the material but it's done . so last night I dropped 2 baskets in the sump of the wet dry.
it's a change of plan ,my spare tank is occupied and life is super busy. went with fluorite,it's the best I could find , and in one basket a sprinkling of chelated iron . so if everything goes accordingly the bacterial colony should be established in february .
side note ; when I put the BCB in the sump the tank received a good cloud of clay dust , although I thought I gave them a real good rinsing , the fish were swimming in the fog , and started to behave in a more excited , active manner . this morning it's
still going on with pursuits ,shaking , bowing and wood pecking ..... just a note we will see
-
Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
Thanks allwet, keep us informed. By the sounds of what Dr Kevin Novak was saying, in the temps discus tanks are kept at it likely will only take 4 - 6 weeks to establish.

Using pantyhose or nylon mesh instead of the knitting canvas that Dr Novak uses helps alot with the dust.

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
I came across Dr. Novak's videos two nights ago and wanted to try it out. I was thinking of using planting baskets as described here:http://www.mankysanke.co.uk/html/anoxic_filtration.html
I got laterite from LFS, and still need the cat litter. Can't wait to try it on 55 gallon tank I have at work (teaching lab). I want to see if it really does reduce nitrates. Also am eager to learn about the results from the rest of you.

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
Hobbies are great for testing new ideas and it's also a lot of fun. But we all agree that this is not a substitute for large and frequent water changes. This seem to be a lot of work to slightly reduce nitrates and phosphates, at the risk of adding many unknowns to the water column.
Couldn't we achieve the same purpose with no unknowns by growing Porthos?
Willie

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
Willie, I must say I strongly disagree with most of your points mentioned.
1. It's not a substitute for large and frequent water changes - I can agree with this
2. This seem to be a lot of work - It is a rather simple build actually, doesnt take much work at all, just 5 minutes of your time.
3. to slightly reduce nitrates and phosphates - Its claim is that it will more than slightly reduce nitrates and phosphates, If it works as intended, it should significantly reduce or practically eliminate nitrates and phosphates. It will also remove many other ions and toxins from the water
4. Couldn't we achieve the same purpose with no unknowns by growing Porthos? - No we could not. Pothos will not do anything other then reduce nitrates and phosphates. Even than, there impact on nitrates and phosphates are limited. Pothos also require light.
5. unknowns - ?, what is there that is unknown? whether it will work or not? If so, that is the point of experimenting.
6. adding many unknowns to the water column - there are no unknowns being added to your water column, kitty litter is just baked clay. It is inert.
-
Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
I think as long as there are large and frequent water changes, then nitrate and phosphate levels will be very low. For the perfectionist, adding some Porthos can reduce it even further. When trying something new, I always ask myself what is the upside and what is the downside. The upside seems small IF there are large and frequent water changes.
There are clearly unknowns in this approach. Baked clay is not clean nor is it inert. It is, by its nature, an attractant - which is why it's chosen for kitty litter. It will attract dissolved ions in the water, but will have had attracted additional ions prior to your putting it into the water column. Clay is used in all sorts of industrial processes to remove certain compounds. I don't know if kitty litter is only baked clay or if additional products have been added. Either way, unknown things are being added to the water column in this approach. The downside is, therefore, unknown.
In my experience, I don't add anything to the water that I don't understand 100%. I'm not advocating against your approach, but simply pointing out an alternative. Using Porthos has no downside, although probably little upside with large, frequent water changes.
Willie

Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
Hey Willie,
I appreciate your concern, but the kitty litter advertised as being natural is simply baked clay with no additives. It is, in fact inert. It acts as an attractant due to its crystalline structure. Essentially, it is just a cheaper version of zeolite. Many people in this hobby seem to forget that nitrogen is not the only toxin in the aquarium nor is the nitrogen cycle the only cycle happening in the aquarium, there are countless other cycles, for example, the phosphorus cycle. Removing Ions, this method of filtration removes many more toxins than typical filtration methods. There have been many informal experiments among the community, some people do 50% every other day, some do 90% twice a day. It is frequently concluded that the more water changes you do the better the growth of the discus. If this method of filtration could achieve growth similar to doing 5 90% waterchanges a day as an arbitrary example whilst only doing 50% every other day waterchanges, why wouldnt we use it. It most certainly couldn't cause any harm, only benefits. I agree about not adding anything to your aquarium that you do not understand, which is why thorough research is necessary. Dr Kevin Novak has done extensive research on this field. This article may give you a better explanation of how it works http://www.mankysanke.co.uk/html/anoxic_filtration.html.
-
Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
So basically, think of it being a zeolite filter, only in a low flow situation. However, typically putting it in a canister with low flow or something like this will clog the filter, significantly reducing to almost completely stopping its effects on the water, whereas this filter simply draws the ammonia and ions in leaving any waste to flow around it so it will not get clogged and lose efficiency. If you are still concerned about the kitty litter, I don't see any reason why you couldn't just use fine zeolite. It would do the exact same thing, just cost much more.
-
Re: DIY "Anoxic Filtration System" eliminates nitrates? Anyone tried this?
Zeolite carries charges on its surface and acts as a non-specific absorbent of charged particles, including nitrate, phosphate and ammonium ions. Because it is non-specific, it will absorb everything else in the water column. Baked clay behaves exactly the same way and is used in kitty liter to absorb ammonium. If it were not for this activity, we could just use sand.
I'm not arguing over the technology, merely that there are other ways to achieving the objective.

Hey willie, I agree with most of what you said here. Simply put, this is just a new approach and more far more efficient way of using zeolite, or zeolite substitute. It is designed specifically to harbour anoxic bacteria to break down all the pollutants the zeolite adsorbs. As for it removing everything from the water column, this is simply not true. It selectively adsorbs ammonium. Their are, however, numerous other chemicals that it will adsorb, but primarily ammonium. As to other ways of achieving this objective, sure, their are other ways. But it doesnt mean they are as simple and cost effective as the anoxic filter. As far as I know, most discus keepers are not looking to spend a fortune nor do they want to set up complex filters to maintain good water quality. In my opinion, the K.I.S.S method is the best. As always, appreciate your input.

Don't clay and zeolites become saturated with cations after a few months, until they are like ordinary dirt?

Hi, I would love to hear an answer to this.
Also, I am not arguing with anyone, I just want clarification. Members who have posted on this thread keep saying that this method is complicated/more work. What part exactly is the hard part???
Thanks.

I think it's just a matter of personal preference. There are many people that feel huge daily wcs and sponge filters is the only way to go. Others are open to the many options out there.

I was going to say nothing about this but after seing it again I could just not resist:
So you do fully understand water? Do you? Do you fully understand all and every filter material, natural and man made sold for aquarium use? Do you? You fully understand sponge used to manufacture simple sponge filters? Do you?
I am constantly reading all over the web that we should reduce our carbon footprint, that we need to preserve the natural resourses but anything that promotes smaller and less frequent water changes is taken immediately as a discus killer.
Come on guys, it is just inert baked clay and laterite (Seachem fluorite red is usefull too and readily available). Just ask everyone to make a couple of BCB (Biocenosis Clarification Baskets) and try them for a couple of months. If it does not work trash them and back to 100% WC every day.
I am not positioning myself in favour or againt this method as I have absolutely no experience on it but I will certainly not trash it until after I test it for myself and see what happens.
In Spain:
22*22*22 cm potting basckets -- 2.20 €
10 Kg kitty litter Carrefour brand -- 2.60 €
3.5 Kg of Seachem Fluorite Red -- 37.39 € (this will do for quite a few BCB)
So all in all, I am determined to test it for myself, if it does not work and I am really dubious of what it promises, I will trash everything or re use the excess flourite for something and call it done. If it works, well I can reduce the ammount of water changes and maybe the frequency too, who knows.
In the meantime I am back to my daily at least 50 % WC in two grow out tanks, one with juvenile discus and other with captive bred altums, plus my three 80 % WC a week in my DT with 17 adult discus.

I totally understand where you are coming from. All too often I see technology and alternate methods get knocked just because someone feels it's "unnecessary" or does not buy into it. Just because you choose not to use these things does not mean it does not work or have positive results.
Some people are fine with doing wcs and leaving their fish flopping around on the bottom of the tank. Others are open minded to other options.
I completely understand the tried and trued method is large wcs but it is 2017 now. There are plenty of other options out there with proven results.
I also fully understand that nothing is a substitute for wcs but I do believe there are plenty of options out there to reduce maintenance for those that are open to it.
Obviously to each their own but I don't feel anyone's method should be forced on anyone else. If there are things you choose not to use, fine, but that does not mean it doesn't work for others

Exactly my way of thinking. Do not get me wrong, I have been doing 100% WC on my grow outs since I started in the hobby. Just two months ago I acquired 8 tank bred baby altums and basically I now share my daily 100% WC into two tanks. I did get rid of 14 juvenile discus and kept only 12 to make things work. So far so good for two months but if I can make arrangements and improve the water quality in my tanks with the same or even less WC why not try it.
Again I am not planing to test it on my existing stock, I have set a separate tank, to be refilled with my dumping water from my existing tanks to start a test tomorro after work. I am planning to add pure ammonia and test the system. It is a small tank with two big BCB but it should reveal what is behing all this matter of Anoxic Filtration.
Time will tell.

Hey nothing wrong with experimenting. I am very much the same way I just recently tried a test with a diy algae reactor and saw obvious results and very quickly.
