Seachem Denitrate is a specialized material designed to remove nitrate from saltwater aquariums through both aerobic nitrification and anaerobic denitrification processes. Its porous structure allows for efficient oxygen depletion at the surface, fostering an environment conducive to denitrifying bacteria in its core layers. With a high surface area and capacity to support a dense bacterial population, Seachem Denitrate can be used in various filtration systems, including drip trays, canister filters, sumps, or box filters, providing optimal nitrate reduction when flow rates are appropriately managed. The product is ideal for reef aquariums where maintaining low nitrate levels is crucial for the health of corals and other sensitive marine life.
