I have the test kit that is recommended on here and do quick chlorine test every evening. Last night my test came back at 1, pool math recommends 6. So I added 172 oz of 7.55 bleach. Used more accurate test an hour later it as at 8, ok no big deal. This morning I checked the drop it was at 7.5, and cc less than .5. My cya on Sunday was 40, bumped it up to 47. Had a bunch of rain which is why cya was lower, had been running 47. Still needEd at least 1/2 ga per day before of 11.9%. Does this seem normal?
