Closed Loop Pump Suggestions- 120 SPS

[Rpierce]

Hey Guys-
I have a 120 "mainly" SPS tank that I want to put a closed loop on and get rid of the two seios. What pump would you suggest? I am going to have to put a piece of balck pvc into the tank because I don't have any holes drilled and the tank is already setup. I was thinking about a Sequence Dart but I thought it would be a littel too powerful. Any Suggestions?

A dart would put a lot of flow into that tank. I'd suggest putting some outlets low and pointing up so you don't blow your sand all over the place. You can restrict the dart outlet with a ball valve without causing any problem with the pump according to MDM. I have one of these on a 180 CL and another on the sump return.
