Flow on a 70G Cube
I have a 70G cube that I was using a MJ1200 mod. It had a pretty strong directional flow that was too harsh on my corals. I have softies, leathers and LPS. Recently, I purchased a Koralia Evolution 1050 and love the dispersed flow. My question is: Where is the best location to put it? On the side pane or the back? I have it on the back corner right now. I have 1 directed flow returns in each corner. I want to be sure and have enough surface agitation so i pointed it up. The frogspawn is very gently moving, not much at all. The blastos are fully distended and open. The yellow polyps are fully extended but not swaying. These are in the middle portion of the tank. The Duncans are at the bottom of the tank and they have a pretty good movement to them. Do you think I need another powerhead to point downward towards the middle of the tank or should I move it to the side?
Cubes are a bit different. I had a 90 long before and had them on each end of the tank. Just trying to figure this out. Wondered if anyone else has a cube with Koralias?
The picture I am including is when I had the powerhead pointed down but there was not surface agitation so I was concerned about not enough oxygen. The yellow polyps you can see are blown pretty much to the side.
Thanks in advance.
