GPH?

Always found the idea of must have X.XX turn overs an hour or or must exactly match your skimmer intake pump little hard to believe. Where's the harm in having your return pump contributing to the overall flow in the display beyond some value through the sump no one can reach a consensus on?

I can a agree there's more efficient ways to get flow in the display than a return pump and so much through the sump you have to put brackets on the skimmer so it doesn't tip over, but I wouldn't be getting overly worked up about matching a magic flow number.

I have probably 4x turn over through my sump. I carefully calculated this based on the cleanest pump I had in my box of pumps, considering clean was more likely to work. MAG12 won, minus head pressure, plumbing restrictions and sludge inside pipes, I figure 4x. Or 5. Or maybe 3.87658. Basically water falls down, water goes back up.
