Hello all, this is our second year for our 18x52 Intex pool. Learned last year that first we have about a 2" drop from one end to the other and also that since its set up between two very large trees you can feel some of the roots under the liner. Plus I hate the hard ground feeling so I was wanting to use a little foam this year This my question is do I put the leg supports on top of the foam or do I cut the foam in a circle to fit the base and put thin pavers under the legs?
