CYA 36 - mine the same. I have been raising this using the sock method in front of the return
FC 8 - mine 7.5 (close) - I added bleach because of high use last weekend have been doing overnight test before I lower it. I am now letting it get back to normal
PH 7.7 mine about 7.5
TA 87 mine 90
CH -162 mine 180 - isC this important for a fiberglass pool? I also have a gas heater if that makes a difference.
I'd call the differences within the limits of experimental error. Unless you or the dealer want to use burettes, balances accurate to 0.1 mg, and analytical chemistry methods as we did in my Quantitative Analysis course many years ago you can't expect much closer agreement.
