    Direct sunlight 7-8 hours per day and effect on CYA/chlorine

    I understand that the more CYA I have in my pool the more chlorine I have to add, but what effect does the 7-8 hours of direct sun I get per day have on the CYA Chlorine ratio. Right now the my CYA is at 50 my chlorine stays between 3 and 5 all of the time...Even in late August I still test daily. The CYA Chart shows that at CYA of 50 my minimum should be 4ppm and my Target should be 6ppm...with the direct sunlight that I get does that effect my minimums and target numbers in relationship to the CYA?

    No.
    If you are maintaining 3-5ppm, then you are doing things exactly right regardless of the amount of sunlight you receive.
