Ok, between 12 inches of rain, a 6 day vacation where I accidently left the swg setting too low (error while testing settings), and the lawn guy getting fertilizer in the pool, my FC got down to 1. Not sure how long it was at 1, and it could have gone lower, but know it only takes a day or less, so I shocked the pool.
Overnight FC loss was 1.5, but CC was 0. I thought you had to have a CC greater than 0 if you have a overnight FC loss.
