If I’m at the upper limit on pH and the lower limit on TA which should I address first? Or does it matter? My pH is currently 7.8 and TA is 70. I know each affects the other, but is it more advisable to lower pH first by adding acid or should I raise TA first by adding baking soda? I entered my numbers into the Pool Calculator and understand the amounts I need to add as a starting point, but was just wondering about the order.
