Dry reef rock (sold per pound) is clean, pest-free aquascaping rock for saltwater and reef aquariums, with MarcoRocks Reef Saver as the representative product. It is natural calcium carbonate (aragonite) rock that is mined on land from ancient reef deposits rather than harvested from living reefs, so it arrives free of nuisance algae, pests and hitchhikers. Its porous structure provides extensive surface area for beneficial bacteria as a tank cycles and matures.
