I did a water change yesterday and siphoned out some stuff from my sump, and ever since my skimmer has been going nuts. It fills up in about a minute. I kept up with it for a while but after burning through my last 4 gallons of SW that I had on hand I had to take the collection cup off. Its now almost 24 hours later and I still cant put the collection cup back on with out it filling up almost immediately. What can I do!??!
