Seachem Matrix™ – High-Capacity Biofiltration Media
Matrix™ is a high-porosity biomedia designed to provide efficient biological filtration for freshwater and marine aquaria. Its porous inorganic structure delivers enormous surface area, supporting both aerobic and anaerobic bacteria, which removes ammonia, nitrite, and nitrate simultaneously. Unlike traditional plastic biomedia, Matrix™ offers internal macropores as well as external surface, giving bacteria optimal space to thrive.
Key Features:
• Highly porous with enormous surface area (>700 m²/L)
• Supports both nitrifying and denitrifying bacteria
• Simultaneously removes ammonia, nitrite, and nitrate
• Inert, durable, and long-lasting – never breaks down
• Can be rinsed without harming beneficial bacteria
• Compatible with all types of wet or wet-dry filters
How It Works:
• Matrix™’s macroporous design allows bacteria to colonize inside and outside the media, providing unmatched biofiltration efficiency. Each liter of Matrix™ offers the same bacterial surface as 170 liters of plastic balls, ensuring a healthy, stable aquatic environment for fish and plants.
