I have heard before about bacteria competing with plants for nuitrients, and
I am a little confused. As I have always understood it, fish waste (ammonia)
is broken down by bacteria to nitritres and then by another bacteria to
nitrates which are then used up by the plants. Now I know that the plants can
also use ammonia directly, but can they not use the nitrates equally well? Or
are the bacteria competing for nutrients other than nitrogen?
