Sand is not a leveling tool
The sand layer is a cushion, not a fix for uneven ground. Level the site by digging down the high side rather than filling the low side, and compact it. Pools need to be very close to level; a tilt shows plainly in the waterline.
Which sand
Mason sand is the usual choice: fine, clean and free of rocks. Concrete sand is coarser. A ground cloth or foam floor pad over the sand adds liner protection.
Keeping it in place
Sand moves with wind, rain and use. A frame, edging or a cover keeps it where you put it. Where sand meets lawn, a border of pavers or timber stops it from spreading into the grass and makes mowing easier.
Common mistakes
Underestimating depth and forgetting extra for settling and spreading are common. So is laying sand straight on sod, which lets grass and weeds come through. Clear and level the ground first.
Measuring the area
Mark the outline on the ground first with paint or a string so measurements match the real shape. Then measure the longest and widest points and the planned depth. Converting to yards and tons is simple arithmetic once those numbers are right.
