Meanwhile, there is another question I would like to ask...

Meanwhile, there is another question I would like to ask. In the beginning of your article you explained about the nitrification process from ammonia to nitrite then to nitrate. And the mistake of most hobbyist of neglecting the danger of accumulating nitrate. From here I got the idea that the main purpose of the Anoxic Filtration system was to break down nitrates by taking the oxygen away and leaving the nitrogen to go free to the air. Meaning that the Anoxic Filtration system is still an integral part of the already existing nitrification process. So if I put it into my pond system the flow will be as follow:
Mechanical filtration:
 Here the solids that might clog the bio filters are separated and backwashed daily.
 Here is where ammonia is converted in to nitrite
 Here is where nitrite is converted in to nitrate
 Anoxic Filter:
 Here is where nitrate is stripped from oxygen and releasing nitrogen thus completing the cycle

I’m sorry if I got the chemistry wrong here. But, somehow from the later parts of your articles I got the impression that the Anoxic Filtration system is a standalone system, not needing the two previous biological steps (Ammonia to nitrite and nitrite to nitrate). All it needs before entering the system is a good mechanical filter. So which is correct, my initial assumption or my latter conclusion?
One more question. About the plants to be planted in the baskets, do we have to plant them? What would be the benefits? What would I be missing if I didn’t plant any? I am looking forward to as minimum maintenance as possible. Okay Dr.Kevin Novak, again thank you very much for your kind assistance. I will be taking photos of my pond later today, and will send it to you along with the kitty litter experiment result to help give you a better picture of my pond.
Best regards,

This photo was take by me from a waterlily growing in an Anoxic filter without fertilizer tabs. Now what hobbyist wouldn't want this in their garden or Anoxic filter? This beautiful flower is what you would be missing if you left plants out of an Anoxic filter. Look at the colors, absolutely breathtaking!


The difference from that of an Anoxic filter and conventional filter is the Anoxic filter does not make a waste product like the bacteria in the Nitrogen cycle does. Either plant and/or bacteria utilize as a food source from all available ions. As you stated in your outline, biofilters 1&2 both produce a waste product that another bacteria has to consume as a food source. The Anoxic filter can do all that and then some with a specialized bacterium without the dependency of a highly oxygenated medium to live on.

 If the bacteria in biofilters 1&2 begin to clog or if a hindrance of oxygen were to become an issue, then that bacterium would suffer, and its ability to carry out the Nitrogen cycle would be compromised. A compromising of bacteria is not even a risk with the Anoxic filter, which is good if you have Koi 20" or longer and overcrowding is an issue and for some reason oxygenation of the pond is stopped or lowered oxygen levels in solution.  Your Koi may suffer but not the bacteria in the Biocenosis baskets.

Each biocenosis basket acts like a giant magnet that attracts ions (positive ions) out of solution; I explain that in my blog. So the nitrogen cycle as you know it and have explained, is not relevant with the Anoxic filter. High oxygen loving bacteria are not its primary reliance; that is only with conventional filtration.

In fact just this weekend I was at someone house looking at a Nexus 300 filter and when the lid was opened the K1 medium was not moving at all and the airline going to the Nexus was broken. How long was it broken, is anyone guess. It just goes to show you that accidents do happen and if for some reason the hobbyist does not check their equipment every day the nitrogen cycle will become compromised very quickly. Not so the Anoxic filter, because all you have to do is get water from point A to point B and if the ion flow stops for some reason (as illustrated in my blog what happen to a hobbyist in the UK) the bacteria will utilize another food source for dinner and its oxygen requirements.

Plants are an option as shown in my blog but all Anoxic filters that are outside benefit from plants. From a cosmetic point of view, WAF (Wife acceptance factor) and taking in cantons and anion out of solution. Not only does the Anoxic filter give you a water garden look with plants in it but also a fancy goldfish pond in the summer months...You can’t put little fishies in a Nexus filter, unless they like hurricane conditions.

I personally like plants but I also like big fat Koi too and it seems like the two don’t mix very well in ponds unless the plants are protected from the hungry Koi. Well, now the Anoxic filter gives you some options; plants or no plants, Koi and/or Goldfish.
