I have a salt pool with an autocover. I test my water every few days. I’m always chasing the PH and TA. I’m glad I watched this episode because now I know why my PH will be 7.8 one day and the next time I test it’s at 7.6. I still don’t quite understand why my TA goes up sometimes 10ppm. I guess I need to do some more reading about Henry’s law. Thanks, for the podcast it really helps us pool owners who are trying to maintain our pools!
