My guess on this is 5x, maybe 6x tank volume turnover per hour.

Any more than that is fine, but the more tank/sump turnover you give yourself the more chance you introduce microbubbles (because the sump can become a whitewater rafting kind of river, even with baffles and dams and etc. to reduce microbubbles), and of course, the bigger your overflow drain capacity needs to be.

You can always increase current in the main display independently of the sump pump (i.e. powerheads, wavemakers, closed loops, surge devices, streams, etc. etc., limited only by imagination )
