Ok, been kee ping shock level up since tuesday. Shocking att night , checking cl, then checkimg cl in the morning. First couple days it was losing about 7 to 8 then last c ouple days days about 4 to 5. last night raised to 18 and this ,m orning , att 10am with sun already out (previosly was checkimg @ 6:30 am) cl was att 16 ..my question now is if I been using liquid cl would I anticipate for cl to be lost att a higher rate than powder cl? The pool water is crytal clear right now and cl loss from last night was 2. The previois night was about same loss also. maybe im done? Thanks
