MSX 200 Not making foam

I just noticed that my protein skimmer stopped making foam for the past few days. It's bubbling but the bubbles are not producing any foam. It's been working great until now.

I've taken out the pump and cleaned it and make sure the impeller was intact.

My skimmer sits on 8-9" water.

Any suggestions?
 
When you cleaned it did you make sure the air inlet nipple on the venturi wasn't clogged?
I use to have an old ER that would do the same thing as you're describing and sure enough I'd clean the air inlet on the venturi and it would perform great.
