return pump

I'm setting up a 120 gl with a 40 gl sump/fuge. I want to set up 2 close lups with mag 95s and was thinking of puting an external pum with low flow to return water from the sump/fuge... what should the minimum capacity of that pump be if I'm also adding two 400 gph power heads in tank... I'm planning to start with a FOWLR and then move on to reef once I have the money for the lights...

any help would be great.

That´s what I figured from a flow perspective... I´m just worried that the force of the water coming down due to gravity would be too much for the pump to manage... I also have a DAS EX2 skimmer that will be placed just before the sump/fuge.
