Meowzer, you'd probably need one Koralia on the other side, possibly two, but I could see you eliminiting 4 easily.
I used to have 3 Koralia 4's and 2 Koralia 2's, plus the return pump and Fluval. Now I have a return pump, fluval and 1 MP40 on 85% Reef Crest mode. Honestly, at times it's a little too much flow in certain areas.
Flower, the flow that they create is much different than your standard powerhead. They have a pulsing current, it's much more like a natural reef.
