My pool is at 60 CYA. I see that my target FC is 4-9ppm. My question is when testing PH what would be my maximum FC in order to still get an accurate PH reading? I have read it to be a max FC of 10 for an accurate reading but is this dependent upon CYA level? Thanks!

Typically 10 or below should still be fine. The higher you go over 10, the more interference you could receive from the chlorine skewing the pH result. Your CYA level is not a factor to my knowledge, but let's ask @JoyfulNoise just to be sure.
