Thanks. I got nervous filling the pool with the rope left untied, so I used the Carrick Bend.

Last summer we had a 12x20 oval, this year we went with the 16' round pool, so we had to level a small amount on each side of the 12'. It all read level. But now that I have 9" of water in it i can tell the pool is unlevel by 1/2". Not sure if I should leave it or drain and re level.
