Seachem Matrix is a highly efficient, high porosity biomedia designed for superior biofiltration in both freshwater and saltwater aquariums. This porous inorganic solid effectively removes nitrogenous waste by providing an ideal environment for beneficial bacteria. Its unique structure enables simultaneous removal of ammonia, nitrite, and nitrate, ensuring a cleaner and healthier aquatic environment.

Each liter of Matrix offers an impressive surface area of over 700 square meters, comparable to 170 liters of traditional plastic bio-balls. Unlike plastic media, Matrix boasts both external and internal macroporous surface areas, perfectly sized to support both nitrifying and denitrifying bacteria. It is completely inert, about 10 mm in diameter, will not break down, and requires no replacement. A single liter is sufficient for up to 100 gallons of water.

This advanced biomedia is ideal for reef aquarium hobbyists seeking a long-term, low-maintenance solution for comprehensive biological filtration. Its ability to remove nitrate in the same filter along with ammonia and nitrite makes it superior for maintaining pristine water quality and reducing the need for frequent water changes. Matrix can be rinsed as needed without harming its internal bacterial colonies, making it a robust and convenient choice for all types of wet or wet-dry filter systems.
