After a skid steer and about 18 inches we finally have the ground ready for our intex 17 x 52 inches. I have 3 questions.
1. Should I lay a tarp down on the dirt then sand on the tarp? Or just lay sand right on the dirt?
2. How much sand do I need? Was thinking 2 yards.
3.what do I do in the winter? Should I cover the spot with a tarp or anything or let it just stay open for the snow? And newest spring will I need to do anything in the spring? Maybe just a bag or two of sand to refresh?

Thank you in advance
