I can switch the way I post the photos - I did it the other way because the resolution of the photos is fairly large.
I got my SWC 120 cone skimmer from spit.fire the other day got it setup at 7.5" depth - but all I get is the cup filling with water in about 2 seconds

I have the air valve wide open and I'v tried adjusting the flow valve but haven't had any success. Anyone have any tips?
