The site looks great and packed full of info. I have a new Atlantis 30' X 52" round above ground pool. My Mother-In-Law bought this pool about 3 years ago but never set it up. So she gave it to us. Sounds great, except it appears to be missing half of the metal for the side walls. The one roll is 47' 2" long and has a sticker that reads "wall size 30' B box 2 of 2". Is it common to have 2 rolls of metal for a 30' pool? Thanks for the help, David.
