Sand is used in aquariums for aesthetic reasons and it also provides the surface area necessary for nitrifying bacteria to grow. We carry the CaribSea Florida Crushed Coral, Seafloor Special Grade Reef Sand, Aragamax Sugar Sized Sand. Typically, you should have 2-3 inches of sand in a saltwater aquarium. For all the CaribSea sand we carry we list the total cubic inches of coverage for that sand.
