Skimmer going crazy

[cpreefguy]

About 5 days ago I dosed with Chemi-clean and turned my skimmer off. When I tried to turn it back on 3 days later after a 5 gal water change, it went crazy. It pretty much just pumps water through the top. Any suggestions?

After running chemi-clean, you are supposed to do a rather big water change. How big is your tank again? On my tank, I had to crank the skimmer way, way down afterward to keep it from going nuts.

Run carbon and adjust the air on the skimmer.
