Caribsea Coraline™ Think Pink Gravels offer a number of unique looks for various habitat simulation purposes. The Caribbean Sea crushed coral's spherical and uniform shape results in good flow rates and makes it very popular with reverse flow filtration in many public aquariums.  Can be used on its own or used as an admixture to other substrates to create unique looks and textures.
