I personally like a slower flow through my sump. Give the naturally filtration time to do it's job :) I wouldn't go anything over 700gph, and even then I'd put a ball valve on it so you can control the flow at any time.

125g 90g 2x33g 34g What stores do I recommend? Up North: Bill ( Saltwater Paradise 801-317-8115 ) Down South: Jerry ( Reef On 801-563-0600 )
A 1600 gh pump with only a foot and a half of head pressure (so prob still 1300+ gph) is going to empty your 20g sump in less than a minute, then overwhelm your overflow... and then flood your home.
