Seachem Matrix High Capacity Biofiltration Media -500 mL

Seachem Matrix™ is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix™ is a porous inorganic solid about 10 mm in diameter.

• 500 mL Size
• Controls Ammonia, Nitrite, and Nitrate
• Supports Aerobic and anaerobic bacteria species
• Highly Porous - Enormous Surface area
• Treats 50-100 gallons

Each liter of Matrix™ provides as much surface (>~700 m²) as 170 liters of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrix™ provides both external and internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Matrix™, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.

Matrix™ is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, Matrix™ may be rinsed when needed without damaging the filter. Matrix™ is compatible with all types of wet or wet-dry filters.

Directions

Use 250 mL of Matrix™ for each 200 L (50 US gallons)** of water. Matrix™ may be placed in any kind of filter, and is particularly effective in a canister filter. Matrix™ is sufficiently large that no filter bag should be required for most applications. Matrix™ works well in drip tray systems, but you may find that the larger Pond Matrix™ is better suited for such applications.

**This dosage may differ from your packaging. Based on updated studies, we've found Matrix™ treats even more water than previously asserted.
