I'm using aragonite sand and puka shell as substrate in my 60 gallon tank. How thick should the substrate be? I heard if it was too thick it would create pockets that could be harmful to the fish.

If you aren't doing plants or using an undergravel filter you really don't need too much substrate. Most of my tanks have between an inch and 1/2 inch of substrate.
