Our temperatures here in AZ have started dropping in the evenings which has also dropped the pool temp from the high 80s and low 90s down into the low 70s.
At the same time, my salt level has seemed to jump from about 3400 to 3800 according to my Hayward salt cell. The pool was completed in May and the salt cell is only about 5 months old.
I just cleaned it this weekend using a 4:1 acid:water ratio and got rid of some scaling on it. It seems like the salt level jumped up around the same time.
So my question is, could the water temp or cleaning of the salt cell cause the salt reading to jump up? I haven't added any salt to the pool since it was opened 5 months ago.
I guess it's also possible there is some salt in my tap water, but I don't think enough to jump my levels up that much that quickly. I haven't been losing any water to much splash out lately, so there shouldn't be a lot of water being added by the auto-fill.
Any thoughts would be appreciated.
