Seachem De Nitrate™ – Advanced Biological Media for Nitrate Control

Reduce nitrates naturally and maintain a healthier, more stable aquarium. Seachem De Nitrate™ is a highly porous biological media designed to support both beneficial bacteria and effective nitrate reduction.

Key Benefits

• Reduces nitrate through natural biological processes
• Supports both aerobic and anaerobic bacteria
• High surface area for maximum bacterial growth
• Improves overall water quality and stability
• Suitable for freshwater and marine aquariums

Excess nitrate can lead to algae problems, poor water quality, and stress for fish and corals. A strong biological filtration system helps convert and remove waste naturally — keeping your aquarium balanced and healthy.

This product is perfect for canister filters. sumps and drip trays.

De Nitrate™ features a unique porous structure that supports two types of filtration:

• Outer layer (aerobic) – converts ammonia and nitrite
• Inner core (anaerobic) – breaks down nitrate

This dual-action process mimics natural reef rock filtration — helping maintain cleaner, healthier water.

Flow Rates matters:

• High flow (>100 US gph): functions as aerobic biological media
• Low flow (<50 US gph): enables both aerobic and anaerobic (nitrate removal) filtration

For best nitrate reduction, slower flow rates are recommended.

If you want to reduce nitrates naturally while strengthening your biological filtration, De Nitrate™ is a powerful and reliable solution for long-term aquarium health.
