Closed loop on 2.5

[penguinsix]

I am trying to put a closed loop on a 2.5 and I am wondering what a good external pump would be. I need around 100gph and wondering if anyone knows a good pump I could use.

You could use a powerhead. Check out nano-reef.com. Someone there made a CL using a mj400 (i think it was). Its posted under the DIY forums.
