OK so I have 2 Hydor Koralia 2's in my 55g. I just don't think I am getting the water movement that I should have would a 3rd be to much. I have tried amny ways and or positions and I just don't seem to have the flow that I see in most reef tanks! I was thinking of adding a 3rd and having it run along the back glass behind the live rock? That way it would come out of the live rock towards the front and cause more turbulance.
