We closed the pool in October 2011 and never opened it during 2012. I just noticed that the water levels are much lower then when we closed it. I also noticed that there are some wrinkles in the corners now. I am wondering if my liner is damaged. I am also wondering if I should add more water. Given that its going to be 30 degress or less over the next few months, should I wait until weather warms up? Any help would be much appreciated as I am super confused and worried right now.
