Thank you. I will lower my TA. pH is usually 7.8 and I add acid as suggested by Pool Tools app. My goal is to lower it to 7.4 or 7.6. Also, I created a signature - thanks for that tip. Pool has been filled from well, but if that's the issue, I can use city water to fill.
I too have high TA fill water but now only add acid when I add water because of evaporation. My pool is stable at a pH of 7.8.
I would suggest keeping a close eye on your CSI (calcium saturation index) and not driving your pH down to 7.4 with the goal of keeping it there.
