First-time above-ground pool owner in Central Kentucky. We have ordered the INTEX - ULTRA FRAME 9' X 18' RECTANGLE METAL FRAME pool. It is due to be delivered on 6/23/22. We are wanting to get a head start and prep for the delivery date. The pool will be going into an area that already has gravel and in a large indoor garage area. I will post pictures of the area tomorrow. We would appreciate any suggestions...…past regrets....or just simply well wishes as we get started...LOL! Seeing lots of suggestions for sand.....gorilla pads....fake grass...etc...as a ground covering under the pool. Again.....a little nervous as this is a big responsibility. But super excited to have my own pool in my backyard!!! Thanks in advance for any help! Happy Summertime!!
