So, it's a chilly week in Texas. I generally don't close my pool in winter since it almost never drops below freezing and we use the hot tub year-round. I just turn the pump down a bit and still keep an eye on pH and FC, the latter of which requires very little maintenance. However, keeping the LSI in a happy spot seems a bit tricky.
Right now, my pool temp is 45, CYA is 50, and calcium hardness is 600. To get my LSI around 0, the two knobs I can play with are TA and pH. I like to keep my TA on the low side (around 60) to limit pH rise. In the past, if I run with a TA of like 80-100, I find myself constantly adding about 8oz of acid to the pool a couple times a week. With a lower TA, my pH seems to stabilize around 8. The math says a TA of 60 and a pH of 8 results in a perfect LSI. But 8 seems way above the normally recommended bounds for pH. If I'm not swimming in the pool much, is there any issue with letting the pH stay at 8 all winter long?
