How has your pool held up? I have had an 18' X 48" for a few years. We are looking to go bigger. I was all for the 22', but my family is wanting the 26'. It makes me nervous! We are moving it to a sunnier area, as last season our pool water temp never got above 78 degrees or so. The ground has been leveled, but we have to remove the bigger rocks and get sand. I plan on ordering a Gorilla pad, too, as we are putting it on the edge of a field. Any help or tips when transitioning to the larger pool?
