Are you running any carbon?

You have to let the skimmer overflow while you drain the cup. I had to drain 25 gallons total from the cup before it calmed down.

You won't get rid of chemiclean with just water changes

To the OP, borrow a uv sterilizer from someone if you can and run it. It should clear it up
