For the longest time, my CH was stable at 325. It is now at 275. I have no idea why. And I don't know what, if anything, I should do about it.
Some more info, in case it's relevant:
Some more info, in case it's relevant:
- My pool is fiberglass.
- I am in process of trying to get my TA lowered, so my pH has been on the low side for a while. I am trying to get the TA to about 50 because my pH kept rising and, from what I read, the solution to that is a lower TA.
- Because my pH is on the low side, my CSI is -0.6 currently
- I'm in Arizona and it's super hot. But last summer was even hotter and CH didn't fall.
