I think I've been wasting bleach, but looking for confirmation. Last season I had my pool at 40 CYA and was targeting 6 PPM when I balanced my pool. After excessive rains earlier in the year, I checked my CYA before this swim season and it had dropped to 30. I JUST realized I never updated my target FC value in the PoolPal app and I've been adding bleach up to 6 PPM when I should have been shooting for 4.
So the question - since I've been over-chlorinating my pool given my current level of CYA, has the extra 2 PPM of bleach just been wasted in the Texas sun?
