Wife got a 16' x 48 " above ground pool two days ago...I didn't want it but for you married dudes out there, you KNOW how it is. Anyway, it's a Intex metal frame. I got a fairly level spot on the ground. Friends at work tell me to take the plunge and get plenty of sand, at least a two inch layer, level it out and then put the pool on top of that. But, won't sand shift a lot even if I pack it and wet it? I calculated about two yards worth of mason sand, two tons. 16 foot diameter circle is pretty big when you map it out. Should I put a ground cover on first, then put the sand on top of that and then put the bottom pool liner (which is a fancy name for a tarp) that came with the pool on top of the sand once it's leveled out? I figure I'm going to keep this thing and if I got to do it, might as well do it right. Appreciate ANY comments on this. I'm also going to get a salt water system for it, about 160 bucks on ebay. Figure it would pay for itself in about two years in comparison to what the needed cemicals costs.
