This our first pool instal. We've leveled the ground, relatively well, I can only hope! We added a layer of left over stone dust that the neighbors had from new construction. Now, I think I need to level the stone, and then we are going to add 1 1/5 inch pink insulation board from home depot and I need to get Gorilla All Weather Tape, is that the best option? I also bought 8x16x4 cement bricks for under the legs. I bought a larger slightly used intex saltwater pump for better flow and upgraded the stairs. We are almost ready to set it up. Any tips to help through those next steps?
