Heterotrophic bacteria compete with nitrifying bacteria for space and oxygen.


           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?
           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.
