Matrix Biospheres is a high porosity media that provides efficient biofiltration for the removal of nitrogenous waste.

It is a porous inorganic solid about 10 mm in diameter, so each liter of these biospheres provides as much filtering surface (< 162 m2) as 40 liters of plastic balls,

Plastic biomaterials provide only external surface area, while these biospheres provide both external and internal macroporous surface area.

These macropores are specially designed to support nitrifying and non-nitrifying bacteria, this makes it different from other forms of biofiltration by removing nitrate together with ammonia and nitrite, simultaneously and in the same filter.

Aerobic bacteria proliferate on the surface, transforming nitrites into nitrates, while anaerobic bacteria are housed within the macropores, converting nitrates into nitrogen gas, which is then eliminated at the surface of the water.

It is completely inert and safe. It does not need to be replaced. Since most of the bacteria are internal, it can be rinsed when necessary without damaging the filter . It is compatible with all types of submerged or external filters.


High capacity biofiltration
Controls ammonia, nitrite and nitrate
Highly porous, huge filter surface area (>~700 m2/L)
Effective against aerobic and anaerobic bacteria species.

Instructions for use

Use 1-2 liters of Matrix biospheres for every 400 liters of capacity. For use in marine or freshwater aquariums.

Format, bottle of 250, 500ml and 1, 2 and 4 liters



Material filtrante excepcional, he probado gran cantidad de material biológico pero sin duda Matrix es el mejor de ellos. Mantengo los nitratos a ralla
