As for foam production, mine doesn't constantly overflow into the cup, as it seems to do this as needed, but it is always foaming. I don't have a heavy bioload in the tank so what I see seems acceptable to me. This skimmer hasn't given me any grief at all, but hopefully Concept will be able to help determine what is going on.

Is your gate valve closed so much that the output water rockets out of the skimmer? I have to use a muffler, which I think is causing problems, but if I don't use it, then I can't quite it down either, as the force of the water is huge, splashing everywhere. Just another problem on top of no foam.
