Water Flow Too Rough?

There's plenty of places in the live rock to take refuge from the current but they wont leave the top of the tank. I shut the powerheads down and they swam around a little bit. Could I have too much flow in my tank?

I don't think two 750s will even be considered as enough flow in a reef tank :P Its around 12x turnover and the clowns shouldn't have any problem with the current. My tank has a 50x turnover and the clowns play around just fine.

My clowns do exactly the same thing - drive me nuts. And no you don't have too much current, if anything the amount of turnover is underwhelming, about 1/2 of what would be considered normal. I have the same 2 power-heads in a 37 gallon for sps.
