What happens to sps
if they don't have "enough" flow? How can you tell? I have 1 jebao MW40 wave maker in my 125 gallon and 4 returns from my sump. That wave maker alone is moving my water back and fourth so strongly that you can see all the polyps moving on all my coral. Is that "enough" flow? Light I get, coral brown or bleach or don't grow, but flow I never really figured out. Right now I seem to have my flow so that my lower LPS
coral dont get so irritated they close and my sps
up top are growing like crazy, would that be the factor that says "ya, you have enough"?
