After the break-in, does the foam start coming up the collection cup?
Cus I just put mine in yesterday, and I see no foam when I keep the small bubbles out of my tank.
Yes, after a few days, given that the skimmer is properly adjusted, it will produce foam. Francis Knudsen has it right; if you SLOWLY adjust the air intake, allowing at least several minutes between adjustments, you should get it right. Good luck.
