I closed my pool on Sunday and drained it about 15 inches, just below the jets and blew them out. Then it rained a LOT the past two days (3-5" according to weather). I noticed my liner doing THIS (pics below) when I came home from work today. It is floating and pulling away pretty good. I read another pool blog that said this can happen if you have high water tables and my back yard does back up to wetlands. The grass around the pool is saturated pretty good. Also FWIW I had a woodchuck problem under the patio when I moved in about a month ago. They are gone but I have no idea how much they burrowed.
The wife isnt happy and is asking me to drain the whole pool. I dont think that is necessary. Im not sure if I need to drain it more, or wait for the floating to go away. Did I drain it too much? about 24" below the coping.
Do I drain as much as I can right now? Wait to see if it subsides (no more rain this week). Do I need a new liner?
Also, what do I do about winterization / Add more algaecide?
In this first pic, the liner is completely above the water line right in the center.
