Anyone know how I can setup a new round Intex 10'x30" above ground pool on a rectangular 7'x13' concrete slab that is surrounded by grass? Can I just use ~20 bags of mason sand and fill the cement area up to meet the grass height? Then put some sand on the grass to make it more level too? Is there a better way to do this? Any suggestions would be greatly appreciated! I also purchased a pool pad as well. This will be my first pool setup and want it to be nice for the kids.
