just looking for some help from people who have experience with the Koralias powerhead.
Ocean Aquatics is have a sale on them and I would like to buy some.
my question is are they 4's too strong? 1200 GPH seems like alot of water movement. does it affect the fish at all?
one of the tanks I want to set up is a 4 foot 130 gallon SPS tank, how many 4's would u put in it? I was thinking 4 in total...is that many, I also want fish in there as well....would this be too much current?
as well, as anyone had any other problems with them?

thanks in advance for any input.
