Seachem De-Nitrate 100ml is a highly effective biological filter media specifically developed to maintain optimal water conditions in aquariums. This innovative, natural, porous material features a strategic pore distribution that facilitates both aerobic nitrification near the surface and anaerobic denitrification at its core. With a superior surface area, it supports a substantial density of beneficial bacteria, making it an efficient solution for nitrate management. At flow rates less than 50 gallons per hour, it operates as both an aerobic and anaerobic filter, while higher flow rates convert it into an effective aerobic filter. This dual functionality is crucial for establishing a balanced and healthy aquatic environment.

• Pore distribution supports aerobic and anaerobic bacterial processes.
• High surface area enhances bacterial colonisation.
• Functions as a dual-purpose filter depending on flow rates.
• Economical and effective in nitrate reduction.
• Ideal for use in a variety of filter applications.

Seachem De-Nitrate's ability to facilitate both aerobic and anaerobic conditions means aquarium enthusiasts can achieve stable and healthy water parameters more efficiently. This dual-action capability makes it a versatile choice for hobbyists seeking to optimise their aquarium's biological filtration processes.

• Volume: 100ml
• Effective Flow Rate: Less than 50 gallons per hour for anaerobic filtration
