## Overview

Seachem Matrix Bio Media Granules offer a revolutionary high-porosity filtration solution with over 700 m² of surface area per liter, supporting both aerobic and anaerobic bacteria. This durable, inert media efficiently removes ammonia, nitrite, and nitrate simultaneously, ensuring superior water quality. Compatible with all filter types and designed for long-lasting use, it’s the ultimate upgrade for professional-grade aquarium biofiltration.

## Description

Matrix is a high porosity bio media that provides efficient bio filtration for the removal of nitrogenous waste. Matrix is a porous inorganic solid about 10 mm in diameter. Each litre of matrix provides as much surface (>~700 m2) as 170 litres of plastic balls! Plastic bio-materials provide only external surface area, whereas matrix provides both external and internal macro porous surface area. These macro pores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows matrix, unlike other forms of bio media, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter. Matrix is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, matrix may be rinsed when needed without damaging the filter. Matrix is compatible with all types of wet or wet-dry filters.

### ⭐⭐⭐⭐⭐ Using along with Seachem Purigen
*by S***R on 27 April 2018*

Seachem products are good, just put it in the filter and forget. I am using it with Seachem Purigen, water quality is great, but I am changing water in every 7 days and my fishes are happy. Hope it is really working. I have goldfish, with Angels and Zebra Fish tank. Just go for it. I am using it in my SOBO WP 3000 F Filter. Thanks to Amazon .
