Carib Sea Seaflor Saltwater Fiji Pink Reef Sand 15 lb
This is a good intermediate sand size product. The precise 0.5 – 1.5 mm grain size combines some of the animal friendly properties of fine sand such as ingestibility and low resistance to burrowing, with better diffusive flux properties and good porosity. Aragonite is purposely engineered and free of impurities such as ash, metals, pesticides, and silica.
