i have a 150 gallon tank (60x24x24) with a juvie oscar, juvie pbass (2) and juvie clown knife. what should my turnover be? the sump will be the only filtration aside from a fbf (maybe a penguin 350)i want to get a pump and it to be fine even when they're older (the knife and oscar will be removed,2 lone pbass) thanks
