I put blocks under the legs of my new intex metal frame pool and now I am wondering if the seam where the heavy duty sides meets the lighter plastic bottom will rip. The lighter weight plastic bottom is not fully in contact with the ground. I only have about 10 inches of water in the pool and it's fairly level. Do you think I need to dig the blocks down level with the ground? If you used blocks under the legs, did you make them flush with the ground? I am just afraid the weight once full, will put too much on that lighter weight plastic and it will burst without the ground to support it.
