Was wondering if my powerheads should be positioned so that they break the water at the top or should I aim them on a downward angle. What I'm looking for is to sort of clear up my water as I see a lot of small bubbles that are always floating around. I have two of them, one on each end of the tank basically facing each other, one on the front part, one on the rear.
