Question:
Can an Anoxic system in a lab with
only the organic matter found in tap water and added ammonia be enough for the
heterotroph bacteria to reproduce to enough to strip oxygen from nitrate?
Response:
Heterotrophic bacteria compete with
nitrifying bacteria for space and oxygen and also sometimes for ammonia. First
you must understand that when heterotrophic bacteria numbers increase or create
more cells as its called because organic load is high like that in your
scenario of tap water, this can lead to a depression in nitrate formation in
the Anoxic Filter and also biological filters and in laboratory conditions this
would stimulate optimum growth even more so.
Simple experiment by Dr. Franco Prati
of Italy:
He took 3 containers half filled
with water (20 liters) then he put inside each container 2 mg/l of NH3. The
first container was for control purposes only and was left alone. In the second
container placed a big Iris Pseudacorus over 1 meter tall. As we all know Iris
do quite well with exposed root systems in our ponds. In the third container he
put an 11"x11"x9" biocenosis basket. None of the three
containers had any moving water in them (stagnated for this test).
3 days later the results were:
container #1 = ammonium 2,0
container #2= ammonium 0,2
container #3 = ammonium 0,00000
This little experiment showed that
even without moving water or stagnated water, the Biocenosis Basket was able to
take the NH3 ion out of solution still.
“QUOTE: Right from Dr. Franco web sight in Italy.
I put 2 @ 9"x9" pots in
my 700-liters aquarium after the biological filter and in 15 days I had:
The results:
Nitrate=8-10 ------------>
before 60
PO4 = 0 (stunning) ----> before
0,75-1,0
..... but I see none is interested
in my reports.

Once again as you can see Dr.
Franco prove that not only did the Biocenosis Baskets reduce the Nitrates in
his tank by 85% in 15 days but also the bacteria depleted the PO4 which is
Phosphate an inorganic chemical.
These two experiments prove that
the Biocenosis baskets even in stagnated waters will still attract ions out of
solution (try that with a conventional filter) By the way this was also proven
by Harvard Chemist, too. He stated that the filter would not die even without
artificial aid or water movement.
The fish tank experiment showed
Nitrate removal when Ammonia NH3 wasn’t present (I’m only speculating here
about the NH3) but an abundance of chemoautrophic bacterial wastes was present.
Both of these experiments done in
Italy answer your question.
Unfortunately no! It’s been
tried and people have fail except in an already established pond. The cycling
time is shortened to a greater degree, very tricky bacteria to grow not under
lab conditions. Hobbyists have tried and failed, best to let Mother Nature do
her thing the right way.
