Hello! Technically I am not new, but I am trying to set up a new liner from my 12x30 steel frame intex. I had some issues with being unlevel, take down, relevel and fill again. Then a pump leak fixed. Lastly a liner leak which led me to send it back for a replacement. I never did locate the leak, so I am not sure of the cause. But I do wonder if it could have been from the pavers I used to support the legs. They didn't dig in really. In fact, hardly touched at all, BUT now I'm concerned about using them again. Half of summer is gone and we're still trying to have a pool to enjoy. The base is sand. Is it necessary to have paver base for the steel legs. I will if it will be a disaster without, but I will try to position them perfectly before filling. Opinions, tips and tricks? Thanks!
