need help picking pump

need to get a return pump and not sure what to get. it will be for a 120 with two over flows any help would be great thanks

 

I have used a mag 12 on that same set up it will work real good. I also used the cheaper brands of pumps that claim 1600 gph but they are not as strong as a mag 12.

 

You need to ask yourself 1st, if you want/need an internal or external pump? 2nd question is, what kind of turn over do you want? For ex. I have a Magdrive 18 on a 90g tank, my turn over is high.
As for which brands are good?
Internal; Magdrives, Tunze, Eheim and Rio(rio being the bottom of the food chain).

External; Iwaki, Gen-X, Little Giant, Dolphin Aqua Sea, Pan World.

A Mag 1800 in or outside the sump would be perfect, or the list that Luna posted for outside will be fine also.

 

There's a link to an in depth article and some other good information on pump selection here. Reefs.org: Where Reefkeeping Begins on the Internet - Welcome to the Reefs.org Pump Selection Guide
