I think what the first poster meant is, if you have to change water to keep
your nitrate level low, then you probably don't have enough plant life to
break down all the available nitrogen so you should use bacteriological
filtering like bio-wheels. If on the otherhand, you have to add nitrogen to
your tank for your plants, then you don't need the bacteria at all.
Actually, I seem to remember writing that bit in parenthesis but I know I
didn't write the rest of the paragraph. Maybe it's just because I explained
to to someone else privately. Weird.
