Kent Marine Marine Biosediment Biofiltration Substrate for Refugiums, Mud Filters, Seagrass Beds & All Marine Aquariums Kent Marine Biosediment is ideal for use in refugiums, mud filters, or as the main aquarium substrate. Slowly releases beneficial calcium, magnesium, strontium, potassium, carbonate, sulfate and other trace materials. KENT Marine Biosediment is a substrate composed of minerals typically found in and around tropical reefs. The average particle size of these minerals is similar to natural reef sediment composition present in reef flats and lagoons. These are areas where aquatic vegetation is both prevalent and important to the reef ecosystem. Although intended largely for use in refugiums and mud filtration systems, KENT Marine Biosediment may be used as a primary substrate in reef and fish-only marine aquariums. Small sand-sifting fishes and invertebrates such as sleeper gobies, burrowing worms, crustaceans, echinoderms, and mollusks can be housed directly within the substrate. Their surface-sifting action may enhance de-nitrification in lower layers. Product Features: · Ideal for use in refugiums, mud filters, or as the main aquarium substrate · Slowly releases beneficial calcium, magnesium, strontium, potassium, carbonate, sulfate and other trace materials Item Specifications: Size: 12lb 6lb
