Tests this am. ph: 6.8-7.0 chlorine: ~1-2....this after i shocked it to 29 based on ppm calculations. I cant believe it dropped that low overnight. I did add about 1 cup or less of borax and 11.375 quarts bleach. I brushed the pool after adding the bleach and borax. I do have some cya ordered to test that but I feel like I am wasting so much chlorine!!! I did finally break down and buy the taylor 2006a kit you have linked to. It does seem to be doing better although I just hate wasting all the chlorine!!!! Once again thanks for the info!!
