These are my test results from last night when I tested the water. I know I need to add more chlorine, which I will do once we are done swimming today. What else should I do? Is the total alkalinity high? I've read the information for how to lower TA and then raise the PH, but I can't find any concrete information on what TA should be. I am using the BBB method.
