Seachem Matrix 1L – Advanced High-Capacity Biofiltration Media for Freshwater & Marine Aquariums.
Experience professional-grade biological filtration with Seachem Matrix 1L, the most advanced biofiltration media trusted by aquarists worldwide. Specially designed to maintain pristine water quality and biological balance, Seachem Matrix offers a unique and natural approach to aquarium filtration. This premium product is ideal for freshwater, planted, marine, and reef aquariums, ensuring that your aquatic ecosystem thrives with clarity, health, and stability.
Seachem Matrix 1L is not an ordinary filter media—it’s an engineered, macro-porous, mineral-based substrate that supports both aerobic and anaerobic bacteria species, enabling complete nitrogen cycling. The result is a cleaner, healthier aquarium that requires less maintenance and provides a safer environment for your fish, plants, and corals.
1. Unmatched Biofiltration Capacity
Matrix is composed of highly porous spherical granules that provide more than 700 m²/L of surface area, giving beneficial bacteria ample space to colonize. These bacteria play a vital role in converting toxic ammonia → nitrite → nitrate, keeping your aquarium ecosystem naturally balanced.
2. Controls Ammonia, Nitrite & Nitrate Efficiently
Seachem Matrix doesn’t just stop at ammonia and nitrite; it goes further by encouraging anaerobic bacterial growth deep within its pores to remove nitrate—something most filter media can’t achieve. This triple-stage nitrogen control ensures stable parameters and reduces the need for frequent water changes.
3. Supports Both Aerobic & Anaerobic Bacteria
Unlike conventional ceramic rings that only allow surface colonization, Matrix supports both oxygen-rich and oxygen-poor bacterial environments. This dual-action filtration mechanism ensures comprehensive detoxification, mimicking natural filtration processes found in rivers and oceans.
4. 100% Natural & Chemically Inert
Matrix is composed of natural mineral rock, completely safe for all aquatic species. It does not affect pH, hardness, or water chemistry, making it ideal for sensitive fish, shrimps, and planted aquariums.
5. Durable and Reusable
Unlike sponge or ceramic media that clog and degrade over time, Matrix lasts indefinitely. Simply rinse gently during maintenance using aquarium water to remove debris—no replacement needed. This makes it a cost-effective and eco-friendly solution for long-term use.
6. Versatile & Compatible with All Filter Types
Matrix can be used in canister filters, hang-on-back filters, sumps, internal filters, and trickle systems. It works perfectly alongside other Seachem products such as Purigen, Stability, and De*Nitrate for enhanced water purification.
Matrix works through biological denitrification—a natural process that mimics nature’s self-cleaning system.
The outer surface houses aerobic bacteria that convert ammonia (NH₃) into nitrite (NO₂⁻) and nitrate (NO₃⁻).
The inner micro-pores provide an oxygen-limited zone for anaerobic bacteria that convert nitrate (NO₃⁻) into harmless nitrogen gas (N₂), which escapes into the atmosphere.
This dual process completes the entire nitrogen cycle, reducing pollutants and preventing algae outbreaks, ensuring crystal-clear, healthy water.
Use 250 mL of Matrix for every 200 L (50 US gallons) of water.
Place Matrix in a fine mesh filter bag for easy handling.
Rinse lightly before use to remove dust.
Position in the filter where water flow is strongest for best performance.
Rinse occasionally with aquarium water—do not use tap water as it can harm beneficial bacteria.
Matrix does not need to be replaced unless physically damaged.
