Denigran Nitrate Decomposition is an advanced biological filtration media designed to effectively reduce and decompose nitrates in freshwater and saltwater aquariums. By promoting the growth of beneficial anaerobic bacteria, Denigran helps convert harmful nitrates (NO₃) into harmless nitrogen gas, ensuring a stable and healthy aquatic environment. Ideal for both planted and reef systems, this product helps prevent algae growth and maintains water clarity for long-term aquarium health.
Efficient Nitrate Reduction: Promotes the breakdown of nitrates into nitrogen gas, preventing nitrate accumulation that can harm aquatic life.
Supports Anaerobic Bacteria: Specially formulated porous structure encourages the growth of anaerobic bacteria responsible for denitrification.
Improves Water Quality: Maintains optimal water conditions by reducing excess nutrients that contribute to algae growth and poor water clarity.
High Porosity Design: Provides maximum surface area for bacterial colonization, ensuring consistent and efficient biological filtration.
Long-Lasting Performance: Durable composition allows for extended use without disintegration or loss of effectiveness.
Safe for All Aquariums: Suitable for both freshwater and marine systems, including planted and reef tanks.
Placement: Place Denigran in a canister filter, sump, or filter media bag located in a low-flow area to promote anaerobic activity.
Preparation: Rinse the media thoroughly with aquarium water before use to remove dust and debris.
Dosage: Use approximately 100 mL of Denigran per 100 liters of aquarium water. Adjust based on nitrate levels and tank bioload.
Maintenance: Replace or recharge every 6–12 months depending on tank conditions and nitrate accumulation rates.
Monitoring: Regularly test nitrate levels to determine the effectiveness of the media and replace as necessary.
Regular Testing: Monitor nitrate levels weekly using a reliable test kit to ensure stable water conditions.
Combine with Mechanical Filtration: Use alongside mechanical and biological filtration media for comprehensive water quality management.
Avoid High Flow Areas: Position Denigran in areas with moderate to low water flow to promote anaerobic bacterial activity.
Ideal for Heavily Stocked Tanks: Perfect for aquariums with high bioloads or where nitrate levels tend to rise quickly.
Sustainable Maintenance: Maintain consistent water changes and use Denigran as part of a long-term nitrate control strategy.
