Slaming the Pool and last night i measured 27.0 PPM. My CYA is 50. I know it's higher than its supposed to be, but i have had algae issues. This morning i checked and my FC whet up by .5. the water is clean and so is the floor. and I don't see any algae. Is this normal?

Must be a minor testing error or the chlorine was not fully mixed last night but I think I would consider it a pass of the oclt
