Good morning all. The issue I have been dealing with is having to add 2-4 gallons(121 oz) of 8.25 bleach per day but passing the OFCLT until this past weekend when I did not pass so started the SLAM process. You can see the results below. My CYA was 40 when I started and this morning still appeared to be 40 so 16 is my shock number according to the chart, however it does not appear to be improving. This morning's loss was 3.4, yesterdays was 2.0. The FC numbers on the lines where bleach additions are made is a calculated number at +1.9 per gallon. This morning the CC was 0, TA -70, CH -300, PH - 7.9, CYA - 40.
Wondering if I am reading my CYA number low and perhaps should bump up the shock number but not sure. Any suggestions would be much appreciated. Also the water is clear and beautiful, no visible signs of algae.
