I added a gallon of Muriatic acid and my pH is still reading 8.2 which means it is presumably higher.
The pool calculator only goes to 8.6. Does that mean that is as high as my pH could be? If so according to the calculator I shouldn't have had to add that much to go from 8.6 to 7.5.
My muriatic acid was a couple years old and I've read that it doesn't "expire" so what gives?
BTW my FC is 5 and my CYA is ~40.
