I have a protein skimmer that seems to stop working at times, mostly after I clean it. This may be a week or more. Should it always be collecting junk in the collection cup or are down times normal? The skimmer is in the sump of a wet-dry in a 125 gallon. It is powered by a Rio 1700. There is a screw on the skimmer you can turn, but no matter which way I turn, the bubbles remain where they are in the tube.
