an idea for great cirulation w/o powerheads

[jmarzullo]

i have a 90 aga and here is what i came up with more or less by mistake. let me say first that i despise powerheads or anything else in the tank. i modified the return to be a second durso drain to get my bluline 100 px-x running at 100%, (1000 gph with head). i then plumbed a closed loop using a mag 9.5 and a scwd. the outputs from the scwd connect directly to the twin returns from my fuge, (1" elbows in the tank). so each return has roughly 500 gph when the scwd is off port and roughly 1300 gph when on port. it creates GREAT movement and all i have in the tank is the 2 returns and a small input for the loop, without powerheads. FWIW...

JM any pics? I have a 90aga and have 5 powerheads to get the flow i want. Your idea sounds great and i have attempted it before however my pump choice was lacking. Pics would give me an idea of what i was doing wrong.

Pics would be nice, I've got a 75 that I'd like to take the PHs out of as well...

I will get a few pix and maybe an mpeg asap.

I have a 120 gal aga and wouldn't mind taking the power heads out.
