I'm sure there is a post related to this somewhere. How much chlorine loss should I expect on 11 hours full sunlight. Numbers are FC 2.5, CC 0, TC 2.5. PH 7.7, TA 90 and CYA 25-30. These were measured late this evening after topping off Chlorine 24 hours earlier and having the full sun today.

It varies a great deal with the air clarity, the water temperature, and your CYA level. Roughly speaking perhaps 2/3rds of your starting FC level per day with CYA around 25-30.
I am pretty new so someone correct me if I am wrong but I think you should keep a higher CYA if you are in so much full sunlight. It will require a higher FC but should require less to maintain the higher FC.
