We are getting ready to install a 27 foot aqua leader pool. We had someone come out to dig the hole. We have mostly sand and rock here. W have spent a few days trying to pick out the rock and for some reason a pretty good amount of glass of of this hole. We are kind of at a loss because we feel like no matter how long we are out there we are never going to get it all and the amount of glass out there scares. I was reading somewhere about putting crushed limestone down and compacting it for a solid pool base. I'm wondering if maybe this is the way too go to make sure the glass doesn't come through the liner or if there is a better way or maybe we just picked a really bad spot in the yard to put a pool. Thanks in advance.
