Live Rock should be at least 1lb per gallon of water. Live Sand, Crushed Coral, should cover around 1-3" of bottom, roughly 55-75lbs. These act as your filter in the tank. For a fish only you only need 1lb per gallon, a reef requires 2lbs per gallon. The more rock the better your living filter is. You can go with Live Rock, or use a Dry Rock, Macro Rock. Some don't like the hitchhickers that come with Live Rock, either one will work. Some will go with the majority of Dry Rock, and seed it with one piece of Live Rock.
