Just purchased a 12' Intex above ground pool. I'm a renter, and although my lease doesn't say anything about NOT installing a pool in the yard, I want to be conscientious about how I install the pool so that I don't have to worry about spending a ton to fix the ground under the pool when I eventually move (which is probably in the next 2 years). I want to avoid using sand to level the ground and I also want to avoid digging. I've looked into foam options but it seems as though the super firm foam that could make a level surface for my pool is very expensive. I don't need this pool to last years and years. If I get one year's worth of use out of it I will be thrilled! So, even something you would consider temporary would be great. And again, don't want to spend a ton of money as this will essentially be a temporary pool at this house.
