Well, I got tired of waiting for hubby to get started taking down the old ultra frame...so I helped him out...I put on my rubber boots and took a butcher knife and enjoyed myself when I sliced a giant sliced down the side of it to drain it! hahaha Heres the old pool that came down as of yesterday....and I totally forgot we had a thick sand base under it. Can we just level the sand base or do we have to dig down to the hard black dirt?
