After reading the instructions for the ss65 (which are as bad as they possibly could be written) I thought I had read the top of the cup should be 1/4" above the water level. If the bottom of the diffuser were to be 1/4" above, the water line would be visible. I was going to ask the same thing. I unhooked my powerheads yesterday and the skimmer went crazy. I found that you can't get rid of the bubbles, and they get swept away in the current of the powerheads. Is this bad?
