is a 3/4inch pvc pipe capable of putting out 500gph at 3.5 feet
or do i need 1 inch its for a diy overflow and return and whats a good/cheap pump that can do 500 give or take 100 at the 3.5feet distance its acually 3.2 but figured rounding up cant be bad

though always see 1" is good for 600gph there's been some discussion on RC is it for a gravity or siphon (this thread (http://www.reefcentral.com/forums/showthread.php?t=1541946&page=66) post 1644 is a table)

although a 3/4" pipe would match the pump a little better going off the chart anyway
