Bullet 3 skimmer

[Redbird5]

I have had my skimmer for 1 month Saturday. The problem I'm running into is the cup is filling up with clear water. The knob is at its highest level and I'm not getting skimmate in the cup. There's lots of foam and it'll drip for a bit and then the cup will fill suddenly with water.
I believe that it's because the water level is too high. How do I know if I've got the right touch?
