Many of you probably have had the same thing happen. I was on vacation and had my sister in law checking on the pool last Friday she added a new puck to the floater...but for some reason I think part of a puck got a way from her and sank...I found them Wednesday when I was vacuuming the pool...they were small. Yesterday (thursday) I was in the pool just swimming and noticed a white spot on my beutiful deep blue liner. It was where I found the pucks...It was sort of brittle and discolored. The liner is less than 90 days old do I have to worry about the liner wearing out prematurely in this spot? What can I do to prevent this? Any suggestions.
