Just bought a house and according to the previous owner, this would be the first time in over two years the pool will be cleaned. It's an 18 x 36ft inground pool with a vinyl liner and sand filter. I've tested the PH and it's 8.2 or possibly higher. If I understand correctly, the PH should be brought up to 7.5 before adding any chlorine to begin killing the algae, but in my situation, should I lower it before I begin?
Also, the alkalinity is 60 and everything else (chlorine, cya, etc.) is pretty much 0.
Thanks,
River
