T-Rex Calci-Sand is the only substrate for reptiles designed to be not only ingestible, but digestible when swallowed. Many reptiles freely eat particules of sand and other substrates in an effort to gain the calcium that they require. Calci-Sand allows this process to occur naturally in the vivarium.
T-Rex Calci-Sand (being a mineral) is safe in direct contact with heating elements. It conducts heat well and it is suitable for use with heat mats or cables buried under it to a swallow depth. It does not harbor mites and inhibits the growth of molds or fungus.
T-Rex Calci-Sand makes spot cleaning both easy and accurate. Calci-Sand clumps readily to wet waste material, drying it and preventing it from being spread throughout the enclosure.
T-Rex Calci-Sand is now available in nine colors: Chocolate Brown, Red Rock, Natural White, Blue, Green, Cherry Red, Biege, Black ,Glo-in-the-Dark and the newest colors: Black granite and Red Rock Granite. All colors are created with F.D.A. approved natural food colorants.
