As a new owner, I opened the pool with green algae. Without doing too much research, I drained the pool and refilled it. The vinyl liner got some wrinkles at the deep end. Besides, the liner looks pulled away at one corner (~ 6'' long).
The ground water table should be not a problem. The liner was fine with the pool totally drained. At the beginning of refill, I didn't pay attention to smooth out the liner. That may cause the wrinkle and high tension at corners.
Is there a easy way to fix the wrinkles with pool filled with water. Thanks.
The pool is ~10 years old, 38'*18' in-ground
I took some pictures but don't know how to post it here.
