Seachem Matrix 500ml

Matrix™ is a highly porous media designed to provide exceptionally efficient biofiltration for single site removal of ammonia, nitrite, and nitrate from freshwater, marine, and reef aquaria.

Each liter of Matrix™ provides over 160,000 cm2 (170 sq. ft.) of surface, equivalent to over 40 L (10 gallons) of typical plastic ball media! This product is sold by volume.

Aerobic bacteria grow on the pitted external surfaces of Matrix™ and convert ammonia to nitrite and nitrite to nitrate.

The pores which cover Matrix™ are home to anaerobic bacteria.

Anaerobic bacteria convert nitrate into nitrogen gas, which is then expelled at the tank surface
