Hi, I went to do a water test today and the first test was for pH. It was extremely low, 6.2 or lower. I stopped doing any other testing as I thought the low pH would throw the other results off. Now I did add acid to the pool last night (Thurs.), only because I haven't added any in a while and the pH is usually high when I do a water test. I was going to add baking soda to raise the pH but thought maybe I should wait a day or two to see if the pH goes up. Any thoughts on if I should add the baking soda now or wait? I don't remember the last time or if the pH was ever so low before. Kind of shocked me to see it. I have had high chlorine levels recently and lowered that to 20%, I even had it down to 0% for a few days.
