    Post  anubisram on Fri Mar 20, 2009 3:54 pm

    Currently reading and trying to digest Dr Kevin Novak's - Anoxic Filtration document
    Has anyone read this and understood if so what are your thoughts

    Interesting stuff although I dont think it has a place in UK koi ponds, just like block built filters you need the extra space. A combination of the old style gravel filter and a veggie filter. Maybe has a place in garden ponds. Koi pond filters mostly now use air to prevent anoxic filters and have a much smaller footprint beacuse of this.

    but we still need an effective way of removing nitrate

    no... your tap water has a nitrate reading - if your filtration is correct then you will be producing nitrate as a by prodauct plus feed increases the phosphate and nitrate result.
    nitrate has been linked to growth issues

    Its not something I have paid much attention to as my supply water has a low nitrate reading and my koi dont suffer from growth problems. Never checked for phosphates do you ? Maybe my setup and dwell time unlike nexus bubblebeads and such which whizz the flow through helps as I have never had an ammonia reading or nitrite either.

    I do have TDS readings though, Tap supply is 120 Pond reading is 150 would this be high if I had a Nitrate problem ?

    nitrate will effect your TDS readings - the other damaging effect of nitrate is here
    Nearly 14 years ago, Takayuki Izeki, writing on behalf of the ZNA
    research division, shared his observations of the effect of nitrate on
    the white ground of Kohaku. He urged that the maximum concentration of
    nitrate be 15 ppm, stating: "anything more than this and the skin
    gradually begins to deteriorate, improving again as the concentration
    lessens." He recommended that if nitrate can be kept at 5 ppm or less,
    "the skin becomes so white it virtually shines". He ascribed the
    negative effect of nitrate on (1) reduced ability to discharge
    metabolic toxins from the body, resulting in build up of metabolic
    wastes in the skin, and (2) on the pond water becoming less receptive
    to dissolution of atmospheric oxygen into the water. He expressed the
    view that nitrate levels above 10 ppm adversely affect oxygen
    dissolving into the water column such that saturation levels at given
    temperatures cannot be readily maintained.

    Haven't really got the space for it...plus does not look like my new pond revamp will be happening - another room needs adding to the house first - so doesn't look like I will have the funding - it looks as if I will have to do a koi giveaway this year Sad

    Will you still be keeping a pond and some of your koi ?

    I think just adding clay and replenish will do the same job.

    sorry to resurect an old thread

    i put 6 biocensis baskets in my veggie filter in march this year.

    can't really comment whether they are a placebo or not but......i don't EVER have a nitrate reading, even going through NPS and the plants in the veggie filter (planted in baskets with just gravel- not in the biocensis baskets) have struggled to establish themselves...now whether this is down to them being planted in gravel only and having to take any nitrates from the water or whether its due to the biocensis baskets starving them of the necessary nitrates.....
