Why are you mixing gravel and sand? Dolomite /crushed coral or sand, you really don't need both unless you are going for a specific look. You can buy nylon netting (in various colors from Walmart or fabric store. They do sell the clear at pet stores or you can use a divider designed for the separaton of gravel colors at a good/larger LFS.
