The CH level in my pool has been steadily creeping up since last summer. It's now at 900ppm. The water is perfectly balanced otherwise and I'm not experiencing any problems with cloudiness or scaling. Should I be concerned?
Currently I'm at:
TC 3.5
pH 7.3
TA 60
CYA 30
borate 40ppm
Last June the CH was at 250 ppm. I have a Liquidator and use only household bleach to chlorinate. The fill water comes in at 80ppm CH. I am in the desert, so there is a lot of evaporation and refill, but I'm surprised that the CH would get this high. I hate to drain & refill the pool because its perfect otherwise. Any advice or suggestions? BTW, its a white plaster pool.
