Mio Thanks for the links which I am slowly digesting. What areyour thoughts on vegetable filters. I tried running one of these a few years back as a form of aquaponics, in the hope of reducing blanketweed. unfortunately it did not work for me and was aborted. I just don,t think I gotthe flow right. I also had problems with areas becoming stagnent and believe this to be the major cause of the proliferation of tricodina and the inibility to heal wounds. Your thoughts on this would be apreciated Regards Dave

There was an enormous debate surrounding `Anoxic` Filtration posted on Koiphen as you probably remember Dave ...



http://www.koiphen.com/forums/showthread.php?94835-Anoxic-Filtration.

In theory it sounds great but what are the downsides ?

Plants attract insects who attract Amphibians/Birds etc who are all Vectors for parasites .... which is fine in a constantly flowing wild river environment which will carry the critters away from the Phish

Such is not the case in even `Semi-Closed` Systems where microorganisms have nowhere else to go ... therefore proliferate infesting the Fish.

Certainly the Blanketweed I experienced following start up of the WLP has died back a little now that the Bulrushes/Lilies and Marginals are in full swing ....

I have zero Nitrate or Phosphate in both systems but lots of Algae type Detritus in the WLP without Koi.

I suspect the Plants will uptake Nutrients the Algae would have flourished on and why I have not needed to `treat` that pond this year.

I doubt planted areas would stagnate Dave due to 02 production at the roots as well as leaves.

I will move these posts over to `Anoxic Filtration` where we can continue the discussion so as not to further `Hijack` Alans Thread

Fair comment. However I don't think it was actually where the roots were, but areas where niether water flowed. or roots took hold. ItI certainly looked and smelled unpleasant whenever the bottom was cleaned out. ie riminded me of boggy areas on the moors. Best regards Dave

Kevin Novak swears Plants purify Water Dave ... and I know they are using Bulrushes etc to do just that ..

http://cru.cahe.wsu.edu/CEPublications/eb1723/eb1723.html

Mike Snaden is looking into a method of reclamation of waste water via a Purification process which might include Plants ... although this is simply a hunch of mine...

Plants inactivate Bacteria and uptake many Metals /Inorganic /Organic Nutrients along with pollutants across the board....

When I incorporated soil in the Plant Baskets I too experienced the foul Hydrogen Sulphide type odours when I lifted these to clean them ... but without substrate in the WLP I have not as yet ..

I want to experiment with the biocenosis pots next year simply to test whether these work Question

This time around my TDS has not increased but the PH did Spike to 10 when the Blanketweed first emerged Twisted Evil the Pond is one third Bulrushes atm.

I understand that they are using bulrushes to even purifiy water in experiments with water which is contaminated with nuculaear waste. I also understand that chemical works who discharge there waste also use bulrushes/reeds for purification purposes.

However My thoughts are that Cleanliness is by far the safest option,anything which has the potential to trap waste including plant roots wether or not in pea gravel or not would have to be cleaned regularly. I am sorry if I cannot get my head around that this is not so. Even if it were not so, I would not have piece of mind. I will leave this to more knowlegable people such as Mike Snaden and yourself to experiment but would be interested in yours and Mikes findings. Best Regards Dave

In Mikes case Dave ... running R/O prior to incorporating his `Profidrum` RDF`s meant copious water replacement in order to maintain ideal TDS Values due to accumulation of waste by-product Nutrients such as Phosphate/Nitrate etc.

The RDF`s have proved very effective in that regard but use 333 gallons each per week via flushing.

Waste Water reclamation is therefore one of his future goals ... and Plants are one means of purifying waste water.

Roddy`s PP treatment would not suffice here in that it will not tackle Nitrate or many other pathogenic bacterial or even TDS components....

Anoxic Filtration is feasible in a Koi pond re pollution balance ,,

I have yet to witness `evidence` via B.O.D/C.O.D bacterial count CFU`s etc or any such battery of chemical testing by members who employ such systems to prove this to be the case .. I retain an open mind though Wink

Pool to Pond Aquaponic conversion

Post by Admin on Sun Sep 25, 2011 6:08 am

Interesting Project Guys.

He has dozens of videos of the conversion ... and heart stopping stocking levels ... albeit NOT Koi Shocked

I wanted to bump this Thread up to post updates on Parameters in the `Tropical` WLP now covered with little surface movement at all.....

The Bulrushes have maintained water quality albeit I have not taken BOD/COD values .. or Bacteria counts ....



PH = 8.16 (too high to promote aerobic bacterial decomposition)

Ammonia = 0.08 of which > 0.0042 is UIA/NH3 Very Happy

Nitrite = 0

Nitrate = 0

Phosphate = 0

KH = 4

GH = 2

DO = 9 mg/l/ppm

EC/TDS = 315/160 respectively.

ORP = 244



I don`t have Laterite in the baskets yet but based upon these parameters I will continue with this `Anoxic` Filtration Experiment for the forseable Surprised

I`m contemplating adding some `Floating` Plants to the Koi Pond currently ... and am about to buy one of these Arrow http://www.ebay.co.uk/itm/Floraduct-Floating-Pond-Planting-Basket-Triple-Pots-/270581196088?pt=UK_HomeGarden_Garden_PondsWaterFeatures_UK&hash=item3effe56538#ht_1884wt_954

What would you be using for the planting medium or can you just allow th roots to hang in the water?

I would like to try `Laterite` Dave such as is used in `Anoxic` Filtration ...

I have myriad Marginal Plant seedlings which have migrated into the Garden`Flower` Pots and taken root from seeds blown into them from the WLP ... So no risk of cross contamination Sweetie .. with these being `DRY` now ...

The roots would then be left to dangle into the water ...
