Hello. We have a 16x32 intex ultraframe rectangular. The liner drops a couple of inches at each of the 4 corners, and water is constantly splashing over them when kids in the pool. If anyone has any advise on how to block the corners off, I would really appreciate it. It's always wet around the pool, which is a problem since it's level. Has anyone seen how this can be blocked off somehow? All advise greatly appreciated. Thanks
