i just purchased an above ground pool 20 ft * 4 ft soft side....
i am putting it on a large concrete slab i had poured a few years ago
do i still need to put sand under the pool?:huh:

Ayuh,... It would probably be Better for the pool to cushion it with a layer of sand...

I installed ours on pea gravel. I laid some old material and carpet that I had hanging around and put a tarp over that.

I think the rough surface of the concrete would soon put holes in the bottom of your pool.
