No, I didn't add bleach after last night's test so I don't know how or why FC went up. Tester error? I am trying very hard to test accurately. Summary of today's test results: 6:30 am, FC = 18.5 and CC <.5 11:30 am FC = 17.5 and CC = 0 3:00 pm FC = 14 so I added 96 oz. of bleach 6:30 pm FC = 18.5
Next steps?
thanks
