Above ground pool

Hello,

i am looking to buy a pool this spring. I have a couple of questions. I am looking at a 18’ or 20’ matrix above ground round pool. I live in Nebraska. Is the matrix resin pool with saltwater a good option for me? I am still deciding where I want to place the pool. Most of my property isn’t level. Can dirt be back filled up the side at all on these pools? I am looking at the pool package. Is there any upgrades that you would recommend?

thanks,

Aaron
