Seaflor™ Puka Shell substrates are great additions to fine sands in reef tanks where animals make their homes by burrowing in the substrate. Jawfish, blennies and burrowing crustaceans will especially appreciate the extra “construction material.” Our substrates are purposely engineered and free of impurities such as ash, metals, pesticides, and silica; which allows you to create a safe and beautiful environment for your fish and invertebrates. Precision grading makes system design a breeze!
