my buddy down the street is building a very long tank, like 8' long 2' wide and 2' high. its almost done and looks awsome. it holds water and everything. the thing is it sectioned off into 3 sectioned of into 3 parts by a wall. i dont know why he did this but anyway. whats a good way to filter this thing. he was going to buy 3 hangover filters. i was thinking cant he drill a hole in the bottom of them and have them all run to a sump or something. anyway.... anyone have any ideas what he should do. thanks
