Seachem matrix bio media is a 4 liter bulk container of highly porous pumice-based biological filtration media that provides an enormous surface area for beneficial bacteria colonization supporting complete nitrogen cycle processing including anaerobic denitrification for nitrate reduction. Matrix is one of the most popular and effective biological filter media available because its unique internal pore structure supports both aerobic nitrifying bacteria on the outer surfaces and anaerobic denitrifying bacteria deep within the stone interior. The seachem matrix bio media achieves what most biological media cannot by providing conditions for the complete nitrogen cycle within a single media. Aerobic bacteria colonizing the outer pore surfaces convert toxic ammonia to nitrite and then to less toxic nitrate through the standard nitrification process. But uniquely the deep internal macropores of Matrix create oxygen-depleted zones where anaerobic bacteria can establish and convert nitrate into harmless nitrogen gas that escapes the water. This denitrification capability means Matrix can actually reduce nitrate levels in the aquarium which conventional biological media cannot do. The natural pumice stone composition provides an incredibly high internal surface area estimated at over 160000 square centimeters per liter which is vastly more than ceramic rings bio balls or plastic media alternatives. This massive surface area means a relatively small volume of Matrix can support the biological filtration needs of very large aquarium systems. The 4L bulk size is the professional volume suitable for large aquariums sumps and multi-tank filtration systems. Matrix is extremely durable and never needs replacement under normal conditions as the stone structure does not break down over time. The media can be rinsed in old aquarium water during maintenance to remove accumulated debris without harming the bacterial colonies. Safe for all freshwater and marine aquariums.
