That exact description happened to me a couple weeks ago with my SWC skimmer right after I re-scaped my tank and re-epoxied every coral I had. It lasted for 3 days then finally went back to normal. I had to throttle the air intake to almost nothing to get it to stop filling the cup in minutes. I think it was the amount of epoxy I used all at once.
Did you move anything in your tank recently?
