I decided to add borates to my pool water and step #1 is to get alkalinity down. My alkalinity has always been a little (~120) high and normally I don't worry too much about it.
I tested on Thursday and my pH was 8 and alkalinity was 110. I added a gallon of muratic acid and retested Friday and pH dropped to 7.5 and alkalinity dropped to 100. I added another gallon of acid and retested last night. pH went down to 7.2 and alkalinity was still at 100. I just tested this morning and pH is back up to 7.5 and alkalinity is back up to 120. I've been leaving the pool running 24x7 to increase agitation.
Am I doing something wrong?
