Brand new pool owner of a 24 foot round above ground pool. The pool company that installed our pool suggested putting down plastic around the pool and securing it with tape before we put our rock down. What kind of plastic do we use as well as what kind of tape? I tried calling back the pool company but I received two different answers so any help would be appreciated, as one person told me to leave the Tape on to keep the pool wall sealed from water spilling over the sides, and one person told me to take the tape off as it was just there to hold the plastic in place. I have also read that rubber roofing flashing also works well to form a barrier against the rocks penetrating the pool? Any help would be greatly appreciated!
