I bought a home with a pool and just had it opened for the first time. I found this site and cant wait to get started. The water is very clean and nice and blue to start. The previous owner had a frog and it appears that the CYA is higher than i would want, maybe from using that frog? But with the numbers that I have (listed below) is a slam even needed if it isnt green? Also the CH seems to be high. Do I need to worry about that with a vinyl pool? I put a pic of the water below as well. Any assistance with where to start would be a big help. Thanks guys!
CYA - 70
PH - 7.6
FC - 21 (I had a company come and open the pool and they added a bunch of chlorine)
CC - 0
TA - 200
CH - 570
