Seachem de❊nitrate™ | Biological Filter Media for Nitrate Control

Reduce nitrates naturally with Seachem de❊nitrate™, a high-performance biological filtration media designed to remove nitrates, nitrites, ammonia, and organic waste from aquarium water. Its unique porous structure supports both aerobic and anaerobic bacteria, helping to maintain superior water quality and a healthier aquatic environment.

Key Features

✔ Removes nitrates, nitrites, ammonia, and organics

✔ High porosity biological filter media

✔ Supports aerobic and anaerobic bacteria growth

✔ Long-lasting and reusable

✔ Suitable for freshwater and marine aquariums

✔ No risk of hydrogen sulfide production like sulfur-based media

✔ Ideal for canister filters, sumps, box filters, and media reactors

Benefits

• Helps maintain low nitrate levels naturally
• Improves overall water quality
• Supports a healthy biological filtration system
• Reduces stress on fish and invertebrates
• Long-term solution for aquarium filtration

How It Works

de❊nitrate™ features a specialized pore structure that allows:

• Outer layer: Aerobic bacteria convert ammonia into nitrite and nitrate.
• Inner core: Anaerobic bacteria convert nitrate into nitrogen gas, helping reduce nitrate accumulation naturally.

Best Results

For effective nitrate removal, water flow through de❊nitrate™ should not exceed 200 L/h (50 GPH). At higher flow rates, the media functions primarily as biological filtration for ammonia and nitrite removal rather than nitrate reduction.

Suitable For

• Freshwater aquariums
• Marine aquariums
• Planted tanks
• Community aquariums
• Cichlid tanks
• Sump filtration systems
• Canister filters

Directions

• Rinse lightly before use.
• Place in an area with water flowing through the media.
• Use in canister filters, media chambers, box filters, or low-flow reactors.
• Allow several days to weeks for bacterial colonies to establish and begin nitrate reduction.

Why Choose Seachem de❊nitrate™?

Unlike standard biological media that primarily process ammonia and nitrite, de❊nitrate™ is specifically engineered to promote anaerobic denitrification, helping to control nitrate levels naturally while providing excellent biological filtration. It is a permanent biomedia that does not require replacement under normal use.
