Is Dennis the new frag man?
Sally, I think my skimmer went nuts because when I turned the vacuum off, I squeezed the bag to get out any water before removing it from the sump, so I wouldn't spill water all over. When I squeezed it, dirty water was flowing thru it into the sump, and for whatever reason, the skimmer went crazy.
It only took about an hour for it to all clear up. I'll just remember next time to turn the skimmer off when I vacuum the sump.
