I haven't been able to find a pertinent thread on the kind of wrinkles we have.

I drained the pool in October and went too far by accident. only an inch or two remained in the shallow end. All the winter rain would fill it a couple of feet, so I didn't add water. I noticed in January that three wrinkles had formed when the cold weather hit after Christmas. They form an x in the bottom with a raised ridge of about an inch high. I was told to wait until the weather gets warmer to try to get them out but fill the pool back up so more wouldn't form. No more have formed.

The pool is filled and now about 70 degrees. It's clean and chemicals are balanced. Now what? one pool company said to empty the pool and they'd stretch it back by hand. Another said leave the water in and use plungers to do something with it.

Any suggestions? Experiences?

Thanks!
