Seachem Matrix™ is a high-porosity biomedia designed to provide efficient biological filtration for removing nitrogenous waste in freshwater and saltwater aquariums.

Key Features & Benefits

 High-Capacity Biological Filtration: Macro-porous stone media provides immense internal surface area for nitrifying and denitrifying bacteria.

 Controls Ammonia, Nitrite, and Nitrate: Supports aerobic bacteria (for ammonia and nitrite conversion) and anaerobic bacteria (for nitrate reduction) within its internal pore structure.

 Long-Lasting & Non-Depleting: Will not break down or require frequent replacement like chemical media; simply rinse during routine maintenance.

 Universal Compatibility: Safe and effective for all freshwater, saltwater, mixed reef, and planted aquarium systems.

 Easy Application: Ideal for use in sumps, canister filters, wet/dry systems, rear filtration chambers, or media reactor baskets.
