• High capacity biofiltration
• Controls ammonia, nitrite, and nitrate
• Highly porous - enormous surface area (>~700 m²/L)
• Supports aerobic and anaerobic bacteria species

Matrix is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix is a porous inorganic solid about 10 mm in diameter. Each liter of Matrix provides as much surface (>~700 m²) as 170 liters of plastic balls!
