 |  Bubbles, foam on top of water
I don't think I have enough flow in my tank.
I have noticed an algae of some type forming on my water surface. It seems to pile up in white bubbles, then turn green. I don't think the flow is good enough in the tank to sufficiently keep the water surface moving.
It is a 20 gallon tank with one zoomed 212 rotating powerhead. It does 125 gallons and is rated to 20 gallons. I have a sea clone skimmer hanging on the back that adds a little flow, but not much.
I bought another powerhead today, Aquaclear 50 (270GPH) but I haven't opened it or put it in.
Thoughts?

I know a generic reference of 10X tank size should be turnover rate. However, for a reef it needs to be more like 20X-30X, some even say 40X!!! I'm shooting for the 30 range in my tank. Flow and water turbulance are a good think in a SW tank. Also think about pointing a powerhead so that it ripples the surface water.

Yeah, that is what I figured.
I barely had 10X of turnover if that. I think the new PH will do the trick.
Thanks | |

Great idea. I might do something like that if I don't switch to the 45 gallon soon. | |
