Closed loop or not?

i love the closed loop system. mine is a spray bar that runs along the back of my tank on the sand behind my lr so you cant see it. extra flow is nice

dallas: i like that idea dude... whats the flow comparison between the hole closest to the bulkhead and the one that is farthest?
detane: i think it depends on your feelings on having a lot of powerheads to rely on for flow. it's also nice to have some flow behind the aquascape so stuff doesnt pile up back there.
