You want to aim at turning over the tank water at least 6-10 times per hour. Many aquarists feel that you cannot have too much water movement, and now days striving for a 15-20 times per hour ratio is not unheard of. We feel this is not necessary for a fish-only tank, but is beneficial for a reef tank. You want to give the tank sufficient water movement and circulation, but not so much that the fish can't move against the currents, or the other tank inhabitants are getting battered by it.
