I have a vinyl liner pool. What is the highest chlorine level I can safely have without bleaching the liner at all? If I have a CYA level of 50, is it really fine to have a FC level of 6.0 constantly if I have a vinyl liner? Just want to make sure.
I bought my house from my parents once they moved to a smaller house out of state to retire, and their last liner became pretty bleached compared to when they first got it. I have no idea what levels they kept the water at, but the when the new liner was installed they said it was pretty clearly bleached from too much chlorine at some point.
Thanks for the help!
