Powerheads

I have two Koralia 3's for my 40g breeder, and no matter where I place them, it's just too much of a powerful flow. My corals look like a hurricane is hitting them!

I replaced one of the the 3's props with a prop for a 2, and it's still too powerful. I just took the powerheads out. So at the moment, the only flow I have is from the overflow and return... I'm running a Mag 7 for that.

Should I invest in some Koralia Nanos? The flow just from the Mag 7 is pretty good, but I do have two dead spots at the back corners where detritus is building up..

Heck, I can not even run #3's in my 120g without blowing the softies all over, I would say #1's, I am not familar with the Nano's. I run 2 #2's side to side and #1's from the back blowing to the front.
