If I understand right a higher TA should drive PH up. If recommended is 100 and mine is 120. But my ph always seems to want to run at 6.8. I really have trouble getting above 7.2. I know you are going to want reading but its almost closing time. I will get the fancy kit at opening. Using pool supplies tester and I know its unreliable especially on chlorine. Test strips show TA a lot higher than 120. But here is what they say.
PH 7.2 This is after adding 12 lb of washing soda(borax)
hardness 17
ta 120
cy 60
copper 0
