We are getting our brand new 30 foot above ground pool installed today and the installers just told us we would have to wait 2 weeks after it fills before swimming so the sand will set. This seems like a very long time to me. We initially thought it would only be 48 hours for it to set without us leaving footprints or ripples in the liner. I can’t find any information on this online. We’ve waited a whole month for this install date and I’m really hoping we can use it before two weeks. Does anyone know if 2 weeks is the correct amount of time to wait for the sand to set before swimming?
