Can too much water current be bad for corals?

[sean obergfell]

I have a 70 gal corner tank with a Korilia 2 on one side and a #3 on the other....it looks like my leater toadstool and torch coral are blowing around pretty good..(could be a good thing) I don't know...Ive read alot but all reading says low..med..or high water flow.....don't know the difference between low and high......How do I know if there is too much or not enough current?

[kev apsley]

if the polyps aren't opening and it looks unhappy prolly too much current but visa vera if polyps are open and it looks happy then it's prolly good...you have to make a judgement call

yeah aslong as the polyps are extending and the coral is not being blown off the rocks then i suppose things are ok! as kev said, just asess the look of your corals! if they look sad, well then i would turn down the flow a bit!
