Vince said:OK, well you have fish in there, and you feed it. Therefore, the wastes the fish produces becomes food for the bacteria. If you have a media from an established tank, the bacteria WILL reproduced and create more bacteria. Changing water aids the bacteria by lessening the ammonia in the water, and in turn also aids the fish against ammonia. If ammonia is contained to low levels, nitrite production is less. And addition of new water again creates an environment with less nitrate. It's not rocket science.
Your logic is flawed, and this is why-
Ammonia is not toxic to bacteria. infact, it is a food source and the first big jump in the nitrogeon cycle.
Heterotrophic bacteria eat away at dead matter and produce ammonia. which is then fed upon by a species of Nitrification bacteria that then produce Nitrite... The nitrite is eaten by another species of Nitrifrying bacteria to produce a chemical called Nitrate... and we all know what happens to No3.... NOTHING, generally, so we must remove it via water changes.
so, to suggest doing water changes to remove ammonia in order to aid the bacteria growth is rediculous and completely incorrect. infact, its the EXACT OPPOSITE.
You also suggested that if NH3 levels were low, then NO2 production would be less... this is common sense and logic can easily prove WHY this is.
Lets see... NH3 is a step BEFORE NO2 production.. so if there is less NH3, OF COURSE there will be less NO2....
its not rocket science.
