8:30 test shows fc shows 16. I added approx 100 oz at the last test. Pool math says to add 77 oz. I"m going to add half and see what it tests in an hour.
1st test this morning it FC at 16 That's a large loss overnight
Retest after 72 oz of 12.5% shows FC 24. I'm off to work and will recheck around 5:00PM.

Yup, that is pretty normal to lose about 50% of the FC to the sun with a CYA of 50ppm. That is why you do not want to have the FC level too much above the target level when in maintenance mode.
