hmm...i dont even know where to start, my tank isnt drilled so i know i'd need an overflow box, other then that i have no idea what kinda pumps to use, or where to put what pipes or anything like that.
they have these things at the LFS it's like a pro aquatics all in one sump kinda thing. comes with some bioballs and some flexible tubing and some foam of some sort...i've been thinking about that, but i guess it'd be better to just get another tank and do it that way...maybe a 10g or something...i dunno
