According to my pool "professional" my CYA is 66. But here is the strange thing. I tested my chlorine at about 2 ppm with my drop test kit before I took the sample in for testing at the store. They tested the sample at 0 FC, 0.57 TC and 0.57 CC. Pool water is perfectly clear and no chlorine odor to speak of. I tested TA at 110, same as the store but they had my pH at 7.9 where I had it at 7.6 both before and after my visit. I know my eyes aren't that bad when it comes to colors. Any advice?

Thanks,

Doug...
