I bought our easy set pool last spring for $400 and set it up and maintained it myself. I didn't have a clue about the chemistry but learned here. I love that pool. My husband and I are looking forward to setting it up again this spring. The 18'x48" was just the thing for the 2 of us to enjoy after work. And now that we know I can handle the chemistry we will build a "real" above the ground next year when we add our new garage. I say go for it and try it out.
The others were right, a flat surface is key to having a stable pool. Oh and not using stabilized chlorine tablets in the floaty dispenser duck. I learned that too. And when you push the liner out at the bottem before filling it don't kick it too hard or you can tear the liner at the seams. We did get a replacement liner in a week from Intex, at no cost, but it was a long 10 day wait. Let us know how it goes, Kimrst
