Too much current???

[Canadian Man]

I don't know if anyone will agree with me or not.
I find that most of my softies adapt over a day or two to any new/stronger current.

I do have differing current (EG.wavemaker) in my tank but when I recently added another powerhead to the tank a few of my corals change their polyp expansion for a little while and then they seem to adapt to the stronger current.

My tank is a 90g 48x18x24 and I have a return from a Little Giant 4mdqx sc with lots of head so lets say 600 to 700 gph from that and another 700gph from powerheads so around 1300 to 1400 gph and my tank is a mixed(sps,lps,softies) tank.
