Help needed

Oh wow. I had no idea re: surface tension of water. Makes sense!

I) How can I tell if there's too much/little air?
2) Also, is there such a thing as the foam rising too fast through the cup? If so, how to remedy that?
3) so when I do a water change and shut off the skimmer for cleaning - is it safe to assume that the adjustments should all be correct and all I need to do is fire the skimmer back up or will I have to fiddle with it every time to reset it??

Here's my next attempt based on your feedback.

Do you have a lot of fish in there yet? How often do you feed the tank?

When I started my tank there wasn't an impressive amount of skimming taking place until the whole thing cycled through and I had a bunch of fish. At first it was murky, now it's nasty dark green with nasty sludge.
