Thanks, Richard.

StaClear, pools vary from year to year for all sorts of reasons. Even if it never happened before, it happened this year. If I was at pool side at your home, and could check everything out, I might give more specific advice. But, I'm not there, so I can't.

Most likely, it's going to take awhile to clear things up. Just follow the list, and report what you find.

Best wishes!
