Does it matter which I adjust first (pH or TA)? I hope not, as I've already added 1 cup of muriatic acid (31.45%).
It looks like you recommend a pH between 7.5-7.6. You seem to recommend a TA level of 60-80 but my Hayward SWG recommends 80-120 TA. Why the big difference?
FYI - I'm noticing scaling and some cloudy water when brushing.
I have a 15K gallon SWG pool.
