OK so I scored a 125 for dirt cheap and my Oscars(2) and polys need an upgrade i wanted to do a sump bit I don't think I'm ready for it could I run 4 massive sponge filters(2 powered with power heads and 2 running on air?) I'm trying to make this as silent of a tank as possible because my father in-law loves my tanks and he want to get into the hobby as well but the running water sound makes him think a pipe has burst somewhere help me out guys.
