Ok I just made new entries for 5:45 pm..FC down to 7.5 and CC .5. Probably down due to periods of intense sunlight and periods of rain storms. Right? ALSO have clear solar cover on ..if that makes difference...
I did NOT lose chlorine during night. Dave said to give it two nights. So I put in enough bleach to bring it back to a FC15 and hopefully I will hold this reading for the morning.
IF SO, do I then let it fall naturally back down to a reading between FC3 and FC 6 per Best Guess Chart???
