I am wondering if any Minnesotans can come out of hibernation and give me their opinion of where to start. We are needing to have the liner lifted (is it worth saving?) and the sand floor redone. It was installed in September 2011. We did not have the foam cove installed as we were told it was unnecessary so the installer made a sand cove. As you can see from the pics, the sand has settled around the floor supports and the bottom rim is no longer making contact with the sidewall. The area is extremely sandy (fine, fine sand) and I don't know if that is playing into it. I don't know if they used a compactor on the sand before installation. Thanks for your help.
