Can you ever have too much flow?? I know the water shouldn't be splashing out of the tank (!) but how do you best determine the correct amount?! These pumps sure are powerful so never had to think about it......would appreciate any comments.
I guess water splashing out of the tank would be one of the main problems, but just as long as there isn't a sandstorm, none of the fish and coral look stressed, and there are no deadspots. I'm still figuring out how much is too much also though.
