Thank you PoolDoc/Ben - I will be working on your list today, I'll get back with a complete report as soon as I can.

I'd like to go ahead a drain about a foot of water, and refill, BEFORE I put in a lot of new chlorine. And then see where the readings are. I'd like to see how much replacing one foot of water will help. Water here is very expensive, but I've come to the conclusion that I have to "bite the bullet" anyway.

Suggestions?

Thanks!
