Return Pump for 72 gallon

[dcel22]

Can anyone suggest a model for a return pump that I could use for a 72 gallon. I want to make sure I have enough flow.
Thanks

check out quiet one pumps, i helped my friend put one in his 70g i think the model number was 3000 or the 4000 but it was rated at 780gph it worked great and really is quiet and they are not that expensive
