Seachem denitrate is an economical, natural porous biological filtration media engineered to support both aerobic nitrification and anaerobic denitrification within the same material. Its unique pore distribution allows oxygen-rich processes to occur near the surface while enabling oxygen-poor, nitrate-reducing bacteria to thrive deep within the core. With a very high surface area, denitrate supports a dense population of beneficial bacteria responsible for breaking down nitrogenous waste. While it has limited nitrate-trapping capacity (similar to zeolites and synthetic resins), its primary nitrate-removal mechanism is biological anaerobic denitrification, making it most effective in low-flow filtration environments.
