Take a look at this blog post: http://blog.ingroundliners.com/?p=321
Pictures look stunningly similar to mine.
I am having the liner replaced this fall. Here is what I have decided to do: 1. maintain my chlorine at 3ppm, no higher except during superchlorination.
2. maintain my pH as high as possible in the "normal" range, or about 7.5-7.8 3. Keep my pool cover open as much as possible (thus making it somewhat pointless, but enabling, I hope, my ability to keep the pH high enough). 4. Keep pool temperature no higher than 80 degrees. I think this will keep my liner from wrinkling. I am curious, however, as to why this information is not provided unless one looks for it very specifically. Other than reading that a low pH can cause wrinkling, I have seen no information about chlorine levels, temperature, and automatic covers as contributing to wrinkling in the general literature. The cover companies sure don't mention ANYTHING about how use of a cover can effect pool chemistry. I have to say the whole experience has left me disgusted and rather frustrated about the level of micro-monitoring I have to do to maintian my pool not in a swimmable state--that is easy--but in a state where I can be comfortable I won't have to relpace the liner every few years.
