is there an ajdustment on the air tubing? let more air in the tube by opening it all the way. it seems that there is more water getting in there than air, so its filling with water instead of bubbles in the collection cup?

check the venturi tube and make sure it's not plugged

Thanks everyone for the help but it was the sponge at the bottom of the skimmer. It is fixed now, thanks again
