The photos that I’m showing here
are of my homemade pre-filter before the Anoxic Filter. I now have 10 Koi from
13”@3 to 25” long and all are only fed once a day ½ cup of food a day and in
the summer they will eat double that amount. The pond is completely covered
like a Quonset hut with 6-mil plastic in the Winter so no airborne pollutants can get in;
like dirt or any foliage from trees and so on.
As the photos show this is an
extremely dirty pre-filter and this is only after one weeks worth of feeding
and Koi waste. Basically the pre-filter is nothing more than an under gravel
filter in a small box and instead of using gravel I use Matala high-density
blue filter media with 2500-gph going through it. My 3600-gph pumps impeller
broke last year and this is my emergency pump online now.
What is my point? The point being
is that if you were allowed to let all the organic waste stay in solution, an
think your biological filter would take care of it without ever cleaning it…like that of a Bog or Veggie filter. Do
you think your system wouldn’t collapse sooner or latter? Do you think it
wouldn’t affect Redox? Do you think biological and chemical pathways would stay
open to chemical mediators with this much or more incoming insults to your
system? My fish capacity to filter is very light; in fact this is the smallest
it’s been in over twenty years now. Koi produce lots of Ammonia and waste and for
this much waste to breakdown into mulm would take months of biological activity
to do so. During the meantime your oxygen demand for hedrotropic and
chemoautotrophic bacteria could supersede that of your animals’, it does
happen.
Here is something to think about,
the Anoxic Filter doesn’t place a burden on the available oxygen in the water
body proper. Yes, the water that goes into the Anoxic filter with oxygen laden
water comes out the same way. It’s actually been proven that if oxygen is at
7.8 ppm then it will come out of the Anoxic Filter at 7.8 ppm, too.
