Would like to get through the rest of the season without buying any muriatic acid if pH level is no biggie. Vinyl liner pool, pretty sure I have a little mustard algae. Pool hasn't really been used too much the last couple summers, and this summer I was pretty neglectful - chlorine dropped too many times. Never any significant algae outbreaks, but a couple spots have come back 3 times now within a few days or a week of SLAM.
I never worried about high pH during shock before, and never had any trouble... but thought I'd ask before running chlorine up to mustard shock levels.
