So I didn't realize that I put my SWG on maximum for a month and I still had a FC of 10 when I took the cover off in April. It's been unusually cool here and not a lot of so chlorine hasn't burned off. How dangerous for the pool liner is a FC of 22 for like probably a month. My CYA is 60? I don't care about fading, I care that it could become brittle and break. Thank you
