Yeah, they are 1300gph, and initially it didn't look that strong in there, but then I added my yellow polyps to the tank the other day, and they looked like were in the middle of a hurricane! So....I adjusted the PH so that the current wasn't so strong, but then I added one of my frogspawns and I had to spend forever looking for a spot where it wasn't looking like it too was being blasted away by a hurricane.
I finally had to point the PH way up, toward the surface of the water, but even then, I had to put the frogspawn UNDER the powerhead and sort of in a corner....so I'm really not gonna have anywhere to put my other three euphyllias, because they all won't fit directly under the PH.
I think I'm going to have to go for two much smaller ph's, and maybe then I can cycle them with the lighting so it is mixed up a bit.
I just know that euphyllias don't like real strong current because their skeleton can damage their tissue...so I'll have to think of something...
