Thanks POSGuy, So you're saying you have a regular ol' liner and the installers installed it in a saucer shape in your pool? That is what I have, essentially a big bowl. 48" at the walls and 54" in the middle. (6" deeper in the middle- sounds like what you have).

Tried to send an e-mail to you, but the forum won't let me, if you'd be willing to answer some more questions from me, I'd appreciate it.

Thanks!
