I am setting up a 75 gallon reef and I need to know how many GPH my return pump in my sump needs to be? Does anyone have any reccomendations as far as a good/quiet pump for the sump?
Return pump for my sump??

they need to be matched with your overflows my experiance is only with hang on overflows and its been 1 hole 600 gph 2 hole 1200gph
so more info is needed for the pro's to help what size holes what kinda overflow and stuff

Golgi...I have always liked Mag pumps for 'in the sump' returns. Since it is a reef you will need a minimum of a Mag 9.5. As the other poster noted though it is important to know about the capacity of your returns and how large the sump is...how many power heads you intend to have in the DT.

This is correct. I like to put a ball valve on the outflow plumbing from my return pump so I can 'throttle back' the flow to match my return(s)...or better still a 'T' off the return plumbing that shunts some of the water back into the sump to recirculate. This recirculation is particularly valuable when
you turn part of your sump into a refugium as macroalgaes like Chaeto like
continued water circulation for best growth.

I don't know this for sure, that's why I am asking. But wouldn't restricting the flow from your pump burn it out quicker?

Using a "T" shunt set-up, as Al Mc suggested, will not restrict your pump.

What causes excessive wear and tear on the pump is restriction to the 'intake', not the outflow.

Restricting the flow does cause it to heat up more usually it is minimal but if you try restricting something like mag 18 back to 600gph your pump will probably be more effective at heating the water then circulating the water.
With built in overflows the size of the pump is not that critical as long as you don't pump more water than the overflow is capable of returning. Don't have to worry about maintaining a siphon like with HOB overflows.
Size will depend more on what you are planning to do with your sump if you are going to just have a fuge then something as little as 200gph would be sufficient if you are looking for additional water volume something from 600-1200gph is probably enough. IMO There is no need to try to turn your whole tank over 30x an hour through your sump if you want more flow without adding power heads inside your tank a closed loop is more efficient for trying to increase the flow rate of your tank then using your return pump.
Pump recommendations I have both Mags and quiet-one pumps both seem to be good and I have no issues with either other than my quiet-one would occasionally stall after a power outage, contacted customer service and they sent me a new pump no questions asked, then soaked the old one in vinegar for a couple of days and now it works flawlessly so props to Pentairs customer service
