You should never completely drain an above ground pool. The chemicals in the vinyl liner that allow it to stretch when originally installed do not last. If you drain the water, the liner will shrink and when you refill the pool there is a good chance that instead of stretching back the liner will rip instead. NEVER drain your pool.
yes, just sand will let grass grow through your liner. im in the process of getting vermiculite installed in my above ground pool, because grass grew through the liner.

To install an above ground pool you will have to level the ground where the pool will be placed. You should then add a layer of sand. You should lay out the bottom rails and connect them as shown in the directions next. Install the walls, uprights, and wall bars. The liner will be installed last.
Yes but you will need to put sand under the liner to protect it from impact.
