Just thought that I would update you on the progress of the pond and send you some pictures.

Hi Kevin,

Just thought that I would update you on the progress of the pond and send you some pictures. All fish are extremely healthy and well and all survived the winter. Last year I said that I had been a bit disappointed with plant growth and you said that the plants would have to relearn how to absorb nutrients again from the water as opposed to compost. Well they have and the pictures are testament to that. We have had an explosion of plant growth.

Not sure if you remember that I was unable to get Laterite last year so used the JBL AquaBasis plus. I don't think it was up to the job, as the plants were looking very sickly spindly and yellow when they started growing in spring this year. I added a couple of treatments of Velda Ferro plus and the plants burst into health. I have not added any other supplements this year.

I did get some blanket weed in the anoxic pond and the main pond at the start of the year but when the iron kicked the plant growth off, this has gone. Next year I will add some iron earlier.

I did not do a winter or spring clean out as the pond was new last year and it didn't need it. I just cut off all vegetation and left the pump recirculating through the main pond, but this winter I am going to leave it running through the anoxic pond but just bypassing the black box pre-filter.

I currently have about 30 x 5 inch fish and all seems well with nitrite and nitrate at 0. This year has also seen "wildlife" in the pond. We had a visit from a very large frog, a dragonfly, and we have pond skaters, snails, and things resembling wood lice, centipedes and a minute see through prawn. We must have also had a spawning at some point because we spotted one tiny 10mm fish.

So all in all we are thrilled.

I converted my 45,000lts (11887.75 US gallons) Koi pond to an Anoxic filter on 6th June 2011 and have had no problems.

David Collins, the one that wrote this little article is from France. He has been writing about the Anoxic Filtration system for many years now on Koi Forums to let everybody know just how good the Anoxic Filtration System really is. How big are his fish you may ask: 25-32"(63- 76 centimeters) long. Not only that but his pond is very overcrowded, too. 

I converted my 45,000lts (11887.75 US gallons) Koi pond to an Anoxic filter on 6th June 2011 and have had no problems. I have only cleaned it twice, the first time after 556 days because there was mulm on top of the baskets and the last time was 4th October 2013 to start with a clean filter when I fitted a rotating drum cleaner.

And so onto today. 

I decided that as some of the Koi were looking a bit full of eggs, I’d encourage them to release them - so popped the brushes in. Woke up the next morning to what can only be described as a hell of a mess. Fortunately after 4 or 5 hours of egg laying there followed 8 hours of egg eating. This pattern continued for 6 days. On the positive side it meant no food for 6 days but left my good water trashed……..

My Ammonia (NH3) was up from 0.32mg/L to 1.64mg/L. Not dangerous at 23°C (73.4°) and 6.8 pH but not to my liking. Nitrite on the other hand was up from 0.17mg/L to 1.03mg/L. So to panic or not? Dr. Roddy Conrad of USA fame says don’t panic so that’s what I did, no salt and no water changes.

What I did do was continue the ‘do not feed’ feeding regime and conduct some daily monitoring with the Hanna HI83203. From the first day the parameters started to fall, the NH3 by 20% per day and the NO2 by 25% per day. Five days later I’m back to feeding 500grms of 44% protein food with NH3 at 0.4 mg/L & NO2 at 0.18mg/L.

Conclusion? The Anoxic filter system is without a doubt the best filter in the world. Everybody should have one.

Garden tour in apple pie country...and the Anoxic Filtration System

Garden tour in

: Five big gardens will highlight Brownsville event on Saturday, June 25

QUOTE from: The Register-Guard

“DIY innovators

"When hands-on landscapers Shelly Ellingson and Rick Krause take on a project at their country home near Brownsville, it’s often pretty unique.
Their bubbling, 4-foot-deep koi pond is a case in point.

Made of split-face concrete blocks, the curved pond meshes right against the wood of a back deck. If the water inside seems unusually clear, it’s due to an anoxic filtration system that incorporates kitty litter, of all things.

Shelly learned of the low-cost filtration technique through an online koi forum. “Laterite in the kitty litter pulls the nitrates and the nitrites out of the water,” she says. “It’s a very inexpensive way to filter it.”

With various other landscape projects underway, including a new fire pit, the couple don’t relax much these days. “But when we do,” Shelly says, “it’s nice to sit there (by the pond). I find something very relaxing about just watching the fish, and watching the lily blooms reach the surface and open up.”
The grounds also include a vegetable garden, and on tour day guests may stroll down to the Calapooia River.”

Q & A TIME ONCE AGAIN:



Q & A TIME ONCE AGAIN:

THIS QUESTION COME FROM THE NETHERLANDS:


Dear Kevin Novak,

Thanks for all your good work on the anoxic filtration system. I am
really interested in this system and would like to get more technical
understanding for implementing such a great system. In the Netherlands,
where I live, it is hard to find good information about this system. As a
farmer I am looking for a biological ammonia filtration system. And I
wonder if your system could do the job, as nature has intended to.

May it be possible to filter high ammonia concentration (14mg/l) on this
filter, by adding more and more baskets with cat litter? If so I could
re-use my 7000 liter of water. I have read that one basket should filter
the ammonia production of active koi per day (33mg ammonia per hour per
kilo bodyweight production is 800mg ammonia per day for a mature koi).
Although the ammonia concentration in koi ponds is lower than in my
situation, I wonder if the facultative bacteria could increase to eat
14mg/l ammonia for lunch.

And what is the maximum amount of water per hour which can be pumped
over an anoxic filter? It might be a solution to increase the
recirculation rate of the water over the filter.

I am really looking forward to your ideas and advice.

With kind regards,

F. Bikker



A: The Anoxic Filtration System is capable of lowering ammonium/ammonia of concentrations higher than the 14mg/l that you stated. The more Biocenosis Clarification Baskets there are, the better the system works on available foodstuff, if that is, it has the chemical insults to deal with in the first place.

You can use your 7000-liters over and over again as long as the stability of the water stays stable enough with ions to hold pH at a constant.

The amount of water that passes through the Anoxic Filter will depend how big the filter is to begin with. The rule of thumb is: The more water that passes through the filter without disruption of sediment or mulm is the best way to use the filter. That is why the diffusion of the water is so important. In the case of the Anoxic Filter, more is better.





QUESTION FROM SINGAPORE:



Hi Dr Novak

I am Cornelius from Singapore. I have read through your excellent blog on the Anoxic Filtration System, and am in the process of setting up one for myself. I would be very grateful if you could help me clarify a few queries?

Regarding Pond Baskets:
1. Is the pond basket (28cm x 28cm x 19cm deep)  I have purchased over the internet the correct one (See attached picture)?

2. Are there enough open lattices at the bottom of the basket? From the picture, it can be seen that some sections of the bottom does not have open lattices. Would this affect the performance of the filter?

Regarding Laterite / Ironite:
3. Do I need to rinse the laterite or ironite before placing them in the center of the basket? I am using ironite and placed half cup of it into a nylon sock before rinsing it. But after rinsing, the amount of ironite that remained in the sock weighed less than half cup.

4. Is the positioning of the laterite / ironite critical? Must it be deeply rooted in the center of the basket? Would it be ok if the laterite is closer to the surface but still covered totally by cat litter?

Regarding Pebbles:
5. For my old filter, I am using Seachem Pond Matrix (Porous Stones) for biological filtration. As I have a lot of them, can I reuse these stones in place of pebbles to cover the baskets? Would they be detrimental to the anoxic system?

Regarding Cat Litter:
6. I am using Sanitcat Pink (Danish Moler Clay) cat litter. It does not clump and retains its structure when wet. But I noticed this cat litter had a fragrant scent upon opening up the packaging. The scent was reduced after rinsing the litter a few times. Would this cat litter be ok for use?

Thank you so much for inventing this awesome system.

Best Regards

Cornelius Tan




This plant basket will do well for an Anoxic Filter.


Q: 1 Regarding Pond Baskets:

1. Is the pond basket (28cm x 28cm x 19cm deep)  I have purchased over the internet the correct one (See attached picture)?

A: The plant basket in your photo will do just fine for the Anoxic Filter.

Q: 2. Are there enough open lattices at the bottom of the basket? From the picture, it can be seen that some sections of the bottom does not have open lattices. Would this affect the performance of the filter?

A: Yes there are more than enough lattice opening at the sides and bottom of your plant baskets.
Q:3) Regarding Laterite / Ironite:

  Q: 3) Do I need to rinse the Laterite or Ironite before placing them in the center of the basket? I am using Ironite and placed half cup of it into a nylon sock before rinsing it. But after rinsing, the amount of Ironite that remained in the sock weighed less than half cup.

A: NO, never rinse the Laterite or Ironite before use. Just place the Ironite in a nylon sock as you have suggested, this will do just fine. You can also if you wish do the same for the Laterite but it is not necessary to do so. The Laterite can be placed directly into the basket in the center as explained on my blog.
anoxicfiltrationsystem.blogspot.com


4. Is the positioning of the Laterite / Ironite critical? Must it be deeply rooted in the center of the basket? Would it be ok if the Laterite is closer to the surface but still covered totally by cat litter?

A: The placement of the Laterite is really not that critical as long as it is evenly distributed inside the baskets. However, most hobbyists keep it in the center of the baskets. The Ironite on the other hand, must only be placed in the center of each basket.




Q: 4) Regarding Pebbles:

5. For my old filter, I am using SeaChem Pond Matrix (Porous Stones) for biological filtration. As I have a lot of them, can I reuse these stones in place of pebbles to cover the baskets? Would they be detrimental to the anoxic system?
A: Very good question and is the best of the lot. Reusing the SeaChem Pond Matrix is not a good idea. If you read my blog I do go into great detail about such filter medium and the good and bad about their use. Please read my articles on filter mediums and then you may see why their use is not a good idea. Just stick to the pebbles to cover the baskets. The links below will get you on a good start about filtration medium.





Q: 5) Regarding Cat Litter:

6. I am using Sanitcat Pink (Danish Moler Clay) cat litter. It does not clump and retains its structure when wet. But I noticed this cat litter had a fragrant scent upon opening up the packaging. The scent was reduced after rinsing the litter a few times. Would this cat litter be ok for use?

A: This is a very hard question to answer because I don’t know the contents of the fragrant/s use in the cat litter. My only suggestion would be make sure you rinse and clean such cat litter to the nines. Then test one of the baskets with a sacrificial lamb goldfishes to see if it will have any ill effect on their health. Some hobbyists have had very good luck with such cat litter and other have had a pond of death with fragrance cat litter.

The Pterophyllum scalare; pronounced [Tare'-o-fill'-um: wing; phyllum = a leaf: [sca-lair'-e: scalare = ladderlike] are a long time member of this 25-usg (94.63-L) antique brass fish aquarium. The aquarium uses a plenum system on the bottom, which I have written before in great detail in other post on Google +.

Water gets change every 6-9 months and the filter is an old Eheim 2227 water pulsating W/G filter. I don’t think this filter is sold in the US any more because of a problem it has with the Styrofoam float getting waterlogged and sticking.  I have three floats altogether and when filter cleaning is required (every 4-6 months) I just swop them out and let the unused floats dry out. This was not an inexpensive filter, but like all Eheim’s it was made to last, and last it has for the past 18-years now.

The Scalare’s are fed on dried bloodworm and dry foods only; no live food has ever been given at all. Temp is at 79-80ยบ F all year long. The Java fern (Microsorum pteropus) is about 25-years old now and has been a resident of this tank for that many years, too.

Here is a bit of information from Manky about the Anoxic Filtration System and its diffuser implementation in the system.

Here is a bit of information from Manky about the Anoxic Filtration System and its diffuser implementation in the system. To read more go to his link in the UK and a plethora of information will be at your fingertips.

QUOTE:
“As said in the article, the diffuser is purely to break up the water flow into the anoxic pond to avoid it disturbing the baskets so the design is left to pretty much to the user but there are some pictures for guidance.

Figure 5 and its accompanying description shows a suggested design. The inset diagram below it and the description alongside it shows how that may be implemented to make a simple shut off arrangement that can be used when flushing the anoxic pond.”

Here some Q&A by Manky about the Anoxic filtration system.

Here some Q&A by Manky about the Anoxic filtration system.


 
Extreme plant growth is not uncommon in the Anoxic Filter.



Q:

Hi everyone

Now I am probably going to get told off for this idea but fortune favors the brave and all that.

I have had a nightmare digging my new pond I am in proper clay and it all below ground 1.8 m. It has filled with water on me collapsed twice and been the most horrible hole in the world, but now its got a base and concrete block walls and its full of water again.

So here is my mad theory

The concrete block walls are porous and the clay behind holds water all year if I don't pump it out. So would I get the Anoxic filter effect from the thickness of the blocks with the clay behind? The way I see it a natural pond uses the Anoxic effect to stay healthy and this only works because it is clay. We waterproof our ponds thus isolating the water from the soils and clays that would give the Anoxic filtration. We don't want natural ponds as they collapse and form shallow dish shapes great for herons.

So do I leave it bare block and free to do its own thing ? What could possibly go wrong...........................

Andy



A:
Anoxic filtration was designed over more than 25 years by Dr. Kevin Novak Ph.D. and it relies on the interaction of charged sites within the baskets, the charges on molecules and the kinds of bacteria that can live in an oxygen depleted environment. It's easy to do if you do it properly but doomed to total failure if you don't. Read how anoxic filtration actually works and how to build something that really works then decide whether or not you want to go down the anoxic route and the benefits it brings.
