My husband mentioned last night that the bottom of the pool seemed a bit "cloudy". I think he is right, there is a milkiness to the water so that when I look at the bottom of the ladder it just seems a bit foggy.
We've had the pool about 2.5 weeks. No problems until now.
My numbers as of this morning were:
The only things I've added to the water are bleach, muriatic acid (initial to bring down pH), and CYA.
I did do an overnight test last night. The FC dropped from 9 to 8 this morning. I went ahead and added bleach to shock level and will continue to add bleach today and do another overnight test tonight.
I do wonder if it might just be a problem filtering? The loss of 1ppm of FC though bothers me. We haven't backwashed the filter yet, it has only risen about 2psi since we started using it. The pool store said to backwash weekly, the manual I think said every 2 weeks or when psi rises 8 to 10 over the clean psi, which it hasn't yet.
I guess the real question is, do you think I'm overreacting to the cloudiness and loss of 1ppm overnight?
