We've just got our 1 year old 27' round ABG pool running. Everything seems fine except for the fact that there appears to be a gap between many of the uprights and the pool wall. I'd say about a pinky finger tip width or so. It's full and nice and sturdy. Is this anything to be concerned about? I'm kinda out in the cold, as the folks that installed are out of business. When i drained it down for winter, i went about 3" below the skimmer frame. It didn't freeze 100% over the winter but got close. Let me know what you all think, thanks!
