closed loop questions???

[sphelps]

Although tank size plays a role, I think an ideal CL would use a reeflo pump and ocean motion device. I also like the pump intake on the back pane of glass and spread over two 2" holes to avoid sand and high suction current. You would also need 4 or even 8 holes for output which could be on the base.

This is one I did a while ago, it has four 1" outputs.







Notice how the OM is on it's side and over the sump, makes cleaning the drum very easy.
