CaribSea Reptilite Calcium Sand – Desert Rose (20 lb bag, case of 2) – A natural aragonite calcium substrate in an attractive rose-pink color, perfect for desert reptiles like bearded dragons, uromastyx, or tortoises. This ultra-fine sand is 100% edible and easily digestible (made from calcium carbonate), supplying supplemental calcium if ingested. Its smooth, spherical grains won’t scratch delicate reptiles and contain no silica or phosphates. Using this sand helps mimic a desert habitat while providing essential minerals like calcium, strontium, and magnesium for healthy bone development, all without artificial dyes or chemicals.
