Just picked up an acrylic 65 with built in overflow for $50 off craigslist. It is 36" x 18" x 24" I am going to build a sump with refugium for it. As far as a return pump I was thinking of either a Mag 9.5 or 12. I want to build the sump as big as I can so the return pump will be submersible. Any thoughts on using these or and other suggestions?
