Hello, my mom and I purchased a 12x24x52 intext pool recently. Ice had other intex pools throughout the years but all the others we put up over top of the grass. For this pool, we had someone come out and remove the top layer of sod, but he used a backhoe and although he did a great job, it left the ground pretty uneven. I've worked and worked at it and have it close to level. Right now we're not quite sure how to go about making it more precisely leveled because the ground were working with is quite hard. Some have suggested having delivered pea gravel, dirt, etc. What do you guys think would be our best option? We did purchase a gorilla pad also. Any help would be very very much appreciated. Thank you please note the photo in the picture shows a 12x24 area and we need 4 more ft on each side for the legs. Also purchased the 8x8 papers for each leg.
