It looks like I am on the right track. After getting no or very low chlorine readings in the morning for the past several days, I finally had a 6.5 fc reading this morning. Watermom, I hope it doesn't happen again, but if it does, I will definitely be following your technique. I thought about doing it, and in retrospect I should have, but I guess each day we kept thinking that this would be the day that power comes back. Thanks for the advice.
