Well here is what is happening. The videos I see of skimmers show a frothy
foam boiling over into the collection cup.

Right now all I have is bubbly water, no foam or froth. When I adjust the
air inlet valve, where should the top of the bubbling water be? down in the
tube, or up top about ready to boil over?

The instructions weren't too clear and I have no idea what I should be
seeing in the very first day of operation.

Anyway, it seems to operate...the column is filled with bubbles. But no
gunk is coming out and the return water puts lots of micro bubbles in my
tank.

I even stirred up the tank so that some of the crap rose up into the tank
hoping it would suck alot of it out.

Skimmers don't work that way; at least, you hope they don't pull out crap
you have to stir up.

Skimmers remove suspended proteins from the water. These are usually
invisible, but some can be seen as sort of an oily film on the surface. If
you don't have decay products, such as dead fish, uneaten food, or fish
urine and feces, there isn't anything for the skimmer to remove.
