I have a brand new 27 ft round pool installed 2 months ago. I just returned from vacation to find wrinkles in a localized part of my pool about 2ft x 2 ft. My floating chlorine holder was sitting on the bottom and I am unsure how long as it was floating when I left. I have had a pool for over 6 yrs and this is the first time I ever encountered this. Is this new pool liner ruined? Any help is greatly appreciated.
