Finally got time for the pool today. (Yes, it’s too late temp wise, but been busy) Testing today, and my ph is, well, about as “fluorescent purple” as it gets. Pool Math said add 63oz to get target from “9” (just guessing, probably 12?) so I did and about 45-60 minutes later, it’s the same. Added another 128oz and about an hour and half later, same. Suggestion? (Out of acid, going to get some shortly)
