I am in the process of building a new tank, and have decided to get extra holes drilled in the bottom for a closed loop. I was wondering what people with closed loops are using for a pump, and if they have any regrets in going with a closed loop. thanks

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.

I regret CL .For the same price you can get Tunze,s and achieve better flow.Plus much easier to service and set up.Tunze,s dont leak!

270 gallon, 6' long, 3' wide, 2' tall.

It's not a hob overflow, it's an external overflow, the side glass is notched.
