I'm confused

[topless]

Everything has been on hold for the past 4 days. Closed the pool cover and haven't been able to open it while we've received 6-8" of rain. If the weather guessers are correct, 2 more days and 2" of rain before it clears off.
I'm sure water temperature has cooled off because the warmest we've been is 74 degrees since we closed the cover.

Had a break in the rain, the water went backwards. No FC- cloudy, can't see the 4th step. Shocked the whee out of it, I stopped counting at 25ppm. Then the rain came back.
