I am in the process of installing a 14 foot diameter Intex Ultra Frame Round pool. So far I have tilled the ground to remove the grass and weeds. Everything seems pretty level, I used 2 8 foot 2x4s to level out the ground some. There were a few holes where I laid down top soil, considering on how it settles in the next week or so, I might rent a sod roller to compact it down. I also plan on spraying weed killer to try to prevent weeds from popping up.
I am looking for opinions on what I should use as the base for the pool? Is it better to use sand or some kind of foam? I am trying to make this budget friendly so cheaper the better! If I should use sand about how much sand do you think I will need for a 14 foot round pool? If I go the foam route, what is the cheapest/most economical foam that gets the job done?
Also, I plan on only keeping the pool up for 3-4 months and depending might not ever use it again next summer.
