Ok I found a source for sand, local masonary supply $15 ton and he said it was for pools.

I cut liner as mentioned above and pulled back. Not sure what I am looking for. Sand is hard as a rock. I tried to level out a bit but needed to first strafe it with a metal rake to loosen it then move it around with a push broom.

The other side had a big puddle underneath and bottom rail was exposed in a few spots. I used shop vac to vacuum out excessive water. Looks lime rain today so I rolled back the cover as best I could to protect sand. some of the edges are exposed in spots hope that is okay.

I attached a few pics ., welcome any comments or suggestions. expect to have liner by Saturday, oops looks like there is no way to attach a photo , sorry.
