I've been gone for a while, and been long time since I set up tanks and currently about to set up a 40g breeder, the sump is a DIY 29g and I have sigle overflow on the center, what pump should I use for this set up.

thanks

If it's for just a return I'd get a fluval sp2. If you plan on running a reactor with it I'd go with the sp4 and just valve it down. The fluval pumps are great. Italian made. My second choice would be a sicce syncra pump.

I would say 700gph return pump would be fine.
Really depends on your set up though.
Length of hose and head height, the capability of the over flow your using,
If your using a wet dry or a refugium, will you have any reactors plumbed in the return side.... Blah blah blah....
