Hello I have an odd issue. The used hot tub was delivered and put on the deck and all of the edges are off the ground by about an inch. So the weight must be in the center. Should I put boards underneath the edges to support it and shim it? Or do I have a bigger problem? The tub is sitting on a platform deck that is on top of pavement. The deck might not be perfectly even. There is no water in it now btw.
