Seachem Matrix™ 1 liter

Seachem Matrix™ 1 liter – World-Class Biological Filtration

Seachem Matrix is one of the market's most capable biological filter media, made from natural pumice (volcanic rock) with an exceptional pore structure. A single liter of Matrix offers up to 160,000 cm² of filter surface area – a surface area that far surpasses most alternatives and provides your bacteria with optimal conditions to thrive and multiply.

What truly makes Matrix unique is its ability to handle the entire nitrogen process. The deep, macroscopic pores create oxygen-free zones inside the rock where anaerobic bacteria can establish themselves and break down nitrate – something most filter media cannot achieve. The result is cleaner water with lower nitrate levels, without extra effort from you.

One liter of Matrix is sufficient for aquariums up to 400 liters and never needs to be replaced. The pore structure retains its function year after year, and your biological bacterial culture remains intact even during cleaning. This makes Matrix an investment that pays for itself many times over.

The material is suitable for all types of filter systems – external filters, internal filters, sumps, and fluidized beds – and the approximately 10 mm granules provide good flow without clogging.

If you choose Seachem Matrix, you choose a lifelong, natural filter media that provides your aquarium with the best possible biological filtration.
