CaribSea Arag-Alive Fiji Pink Reef Sand is a soft pink colored, 100% aragonite substrate that is a good intermediate sand size product. The precise 0.5 - 1.5mm grain size combines some of the animal friendly properties of fine sand such as ingest ability and low resistance to burrowing, but with better diffusive flux properties and good porosity. This is also the standard choice for reef aquariums at 1 pound per gallon.
Makes it easy to set up an aquarium. It’s ready to work, clears quickly, and contains millions of live bacteria to cycle super fast and create a natural biological balance. Arag-Alive suppresses the dreaded new tank syndrome, compresses the ammonia cycle, and discourages nuisance algae.
