This is our second year with this pool, had to re-level the ground this year. I fought and fought with it to get the wrinkles out and started to fill it up. It's half way filled and there are still big wrinkles. Any chance the weight of the water and movement of swimming will force the sides out more, taking the wrinkles out? Again this is the ultra frame, so there is no frame work on the bottom portion of the pool.
