5x - 10x the tank volume per hour are good values to shoot for.
For 90% of the average tropical and cichlids under 7" I agree with you but for a large wet pet like a midevil I shoot for 10x min. How ever I use 4 ac
50's on my 55 with the hybrid for 800 advertised gph
. It's probably more like 650 with media. This way the actual turbulence in the tank isn't bad and there are no dead spots.
