My skimmer isn't working, I open the valve? And the bubbles still won't come to the top of the collection cup!! It keeps spitting out micro bubbles!! I've have this for about 1 year that I bought used from another guy. It's on my 29 gallon fowlr. I have 2 clowns, 1 purple fire fish and a green chromis.
