I'm trying to figure out this CYA level thing. Right now my CYA is at 35. It is within specs recommended on this site. But I do get direct sunlight from sun up to down, so maybe I should have it higher as it is recommended for full sunlight?
And I am also wondering about chlorine use in regard to efficiency. With higher CYA my target FC raises. But does that mean that with higher CYA the FC used by the pool will decrease or change at all?
So should I raise my CYA, and if yes what is the benefit?
Here are my current test results:
Thanks for the help!
