I am leaving main gyre circulation alone. It got me into trouble last time, but that could have been weak corals.
So what I did is I have turned up return flow a bit. (Nothing drastic). It runs the sea swirl flow is always on the move. No direct laminar flow since it bounces off the glass. Plus extra flow will reach the left side or tank better to sweep the tuninaria, which loves the new higher perch spot.
BONUS is I wanted to turn return up anyways since more flow means more flow thru algae scrubber, so a win win.
