Seachem Matrix is an advanced, high porosity biomedia designed to provide superior biological filtration for both freshwater and saltwater aquariums. This innovative media efficiently removes harmful nitrogenous waste compounds, ensuring a healthier and more stable aquatic environment for your inhabitants.

Composed of a porous inorganic solid, each piece of Matrix is approximately 10 mm in diameter. A single liter offers an astounding surface area exceeding 700 square meters, significantly surpassing traditional plastic bio-materials. Its unique structure features both external and internal macroporous surface areas, ideally sized to support diverse colonies of nitrifying and denitrifying bacteria. This enables Matrix to simultaneously eliminate ammonia, nitrite, and nitrate within the same filter system. It is completely inert, will not break down, and never needs replacement, allowing for easy rinsing without disturbing the established bacterial colonies.

This product is perfect for any aquarist seeking a highly effective, long-lasting, and low-maintenance biofiltration solution for their freshwater or saltwater setup. Its ability to tackle all three major nitrogenous wastes—ammonia, nitrite, and nitrate—in one step makes it an unparalleled choice for maintaining pristine water quality and reducing the need for other nitrate-specific removers. Compatible with all types of wet or wet-dry filters, Seachem Matrix offers exceptional value and performance for long-term aquarium health.
