Just wanted to share my weekend project. Got a bunch of tanks for very cheap. Build a sump and overflows and stuff yesterday. The plumbing for the water coming from the pump is all going to change this was somewhat temporary and not the design I really wanted to do (I can reuse all the plumbing so no big deal). For the filter it is a wrapping paper tupperware box with bioballs in the middle. The pump is one I got at Lowes on clearance for 10 bucks (I got so much crap at lowes for ridiculous prices on pumps/ponds/bioballs/etc I gonna be busy for awhile using it all !) Anyway pump is 320 gph at 0 head. With my setup currently connected to 4 20s it does around 60gph to each tank. Anyway I wanted to share. Oh and the 10 gallons are not hooked up to anything yet.
