i know it's all about nitrate build up and i don't want to sound like an idiot but i'm having some definite aggression issues and need to shuffle some fish around soon. would 5 pbass (7-10"), 2 dats (3" & 5"), and 6 bichir (11"+) be over kill in my 90? filtration is 2x ac110's with twice the normal bio media, an xp3 with only sponges and the rest bio, and an 8" sponge filter? i have got to figure something out. thanks for any help.
