Actually it sounds like your right on target. The general rule of thumb is that a reef tank shoud be turned over a minimum of 10x per hour. Sps
tanks can be turned as much as 20-25 time an hour. Softies and LPS
, in general, dont like the stronger current, so you want the power heads to point in a direction that will not directly impact them. I have several of mine that point across the back glass or push under a nearby overhang.
It may be a simple problem with the placement of the power head.
