Started recently with TFPC, its been so helpful thank you. But running into issue with my PH, finally got it down to 7.2 (from 8.2+) after dumping 1.5 gallons of of 31.45% muriatic acid at 7Am. Tested around 1pm and got a 7.2 reading, just retested and its now at or above 8 again. I guess my questions are: 1. is it safe to constantly dump these large quantities of acid in (pouring slowly near return and then leaving pump and waterfalls on all day) 2. is there another way to lower? 3. what is the cause?
The previous owner's pool boy said he was never able to keep it low and was 'satisfied with a 7.8 for this pool". Starting to worry about how much this is going to cost. Thanks for any suggestions.
PH at least 8.2
