So my pH always drifts up. Using the Taylor test kit for Bromine, my initial readings were as follows: TA 60 ppm pH 8.0 (or more) Bromine 9 ppm CH 250 ppm Added some baking soda to get TA closer to 75 Added some muriatic acid to try to get close to 7.5 Regardless of TA the pH always seems to be at 8 or more until I lower it. 350 gallon tub, 100 deg. F Maybe I just need some borates. Any thoughts?
