I feel so uneducated right now....
FWIW, your too high TA and way too low CYA is what is contributing to your too high pH. Get the TA down to about 70 ppm and the CYA up to 80 ppm and your pH will not rise as fast and there will be less tendency to scale. We really need to know your Calcium Hardness history.
This statement is confusing to me. The water in AZ is very hard and I have drained my pool twice since it was built in 09. I am not sure how to get the TA down and the CYA up but would love to learn. The pool test companies tell me the water is too hard and suggest draining it but it is too hot right now. 110-114,degrees.
I purchased a second cartridge and could pull off some of the chalky powder and lumps to test. What will that tell me?
The problem is my home is not being rented and I know live over an hour away one way. I dont trust the pool services so I go and clean the filter/cartridge and salt cell once a month.
Thank you for your expertise and your patience.
