Harry,

My CYA is 42, taken with a drop test. So, I'm not supposed to have total chlorine? I'm guessing this by the statement that I still have total chlorine so there is something in my pool that is using up the chlorine???? I will try the backwash to waste tonight. Man, I am so sick of this pool. Ugh. I used to have a life.

Thanks to everyone for all your help so far!!!

Kathy
