why do you feel that is to much flow?
most would say a 40x turn over rate ( 90G = 3600 gph ) is a minimum for keeping SPS. my tank is a 120 ( 6" wider than a standard 90 ) and i have 5220 gph ( 43.5x turn over ) and it doesn't look like there is to much flow.
as pointed out above water quality is very important and so is lighting and flow, i would double check all your params and increase your flow, to start.
