I know some of you guys run a few more than a handful of tanks and have them on racks. Whats the most cost effective/filter effective way to do it? A big pump hooked up to some pvc that feeds lines to the tanks to run sponge filters and air stones? I have it like this just wondered if everyone else does this, I know if you were to go HOB or canister on a lot of tanks your electric bill would be through the roof. Maybe on the more heavily stocked one's I can imagine throwing a HOB, but for the most part I use sponge, any one care to share their set up for multiple tanks on racks?
