Caribsea Rubble Zone

The sky’s the limit for uses of this clean, high quality aragonitic rubble. For saltwater, the Rubble Zone can be used for attaching coral frags, refugiums, biological media, reef tank substructure, cryptic zones, or even jawfish habitats. For freshwater, it can be used as a pond filter media, or an African cichlid nesting area. Pieces range from approximately 1-4 inches. Weight: 6 lbs.
