CYA depletion through evaporation

[BC]

Quick question. I have to add ~ 4% of reclaim every other week due to evap. Can I expect the CYA level to drop accordingly? How about salt and calcium content?

No, none of those things leave the tub through evaporation. The only way they are removed is through splash-out or water replacement.
