I'm getting a pool for the first time ever. I have always wanted a turquoise blue pool, but trying to pick out liners is crazy! I can't find photos with real pools using the liners anywhere. I'm debating between Vynall Sandstone, Rhapsody, Serenity or Tranquilty base...anyone have any of these? Thank you so much!! I'm so excited to have found this site! I can see it will be a wealth of help....
