I am about to put up a 24' above ground and would like some suggestions on the foam floors. I am getting my pool dug out about 2-2.5ft and then compacted. I was looking into the gorilla floor bottom but have read that it isnt to thick and then I read about "Pink Foam" is this just something I can get from my local home depot? How thick is everyone using? And can I get by without sand if I have a foam bottom and stick on foam cove?
