This is the sump design I have in mind


Tank Stand is 80"x 34"x38"

I'm looking for suggestions on an external pump for my newly updated system. I had a 110 gal system with a basement sump that was powered by a Blueline HD40. The tank leaked so I'm replacing it with a Marineland DD 250 gal - very cool! But now I need more flow to achieve at least 4x turnover. Please give me your feedback for potential options that meet these parameters:

1) I want at least 1000 gph at ~12 feet of head pressure. I currently use my return pump to feed my fuge & GFO, ...
