I recently had an in-ground, 13,300 gallon, saltwater pool installed. I have been working to lower my TA and pH with muriatic acid. I've added over a gallon over the last week or so, but now my TA is reading 60-70ppm while the pH is still holding at 8.0-8.2. I'm afraid to continue to add muriatic acid and cause my TA to drop even lower. What can I do to bring the pH down to an ideal range and get my TA back up to the ideal range as well?
You will have to raise your total alkalinity using alkalinity Increaser to around 125ppm, then add more Muriatic acid to lower both pH and TA. TA should read between 80-120ppm and ideal pH level between 7.4 and 7.6 , if pH is still high and TA is out of range, repeat the process by raising TA and adding Muriatic acid to lower both pH and TA.
