Pool Instalation

Sorry for the late reply. The Harborlite was suggested as a replacement for the sand as the base. I think I will go with the sand.

Go with the normal sand, the harborlite sounds a little on the expensive side based on the long words used in it's description, besides, I don't think anyone's going to be eating off it!
What good is food grade filtration sand under your pool - it'll be that (food grade) for about the first five minutes until it gets pushed around and mixed with the dirt and clay and then just becomes regular sand with a certain particle tolerance.
