Just had a quick question. My pool was filled with well water. It’s 22’ intex. 13,200 gallons. Temp is 78 degrees. Total and free chlorine is good. Ph is 7.8 which is little high. Akalinity is 280. I’ve used almost whole gallon of muratic acid and it drops a little bit not much. Do I need to get ph down first before akalinity or vice versus. Is this an unheard of amount of acid.
