Seachem De*Nitrate 500ml – Advanced Biological Nitrate Removal Media

Seachem DeNitrate 500ml is a highly porous, natural filtration media designed to promote anaerobic denitrification, effectively reducing harmful nitrate levels in marine and freshwater aquariums. By mimicking the nitrate-reducing capabilities of live rock, DeNitrate provides an ideal environment for beneficial bacteria to thrive, helping maintain long-term water quality and a healthier aquatic ecosystem.

Unlike standard biological media, De*Nitrate is engineered to function best under low-flow conditions, allowing oxygen to be depleted within the media and enabling nitrate-consuming anaerobic bacteria to work efficiently. This makes it an excellent solution for controlling nitrates without constant replacement, provided nitrate levels remain stable.

Ideal for use in canister filters, chemical filtration modules, and box filters, Seachem De*Nitrate is a reliable, long-lasting choice for aquarists looking to combat nitrate buildup and reduce algae growth.

Key Features:

• Promotes anaerobic denitrification to reduce nitrates
• Replicates the nitrate-removal function of live rock
• Extremely high surface area supports dense bacterial growth
• Long-lasting media — not exhausted if nitrates remain controlled
• Helps prevent algae growth caused by excess nitrates
• Suitable for marine and freshwater aquariums
• Best performance under low-flow conditions (≤200 L/hr)

Seachem De*Nitrate 500ml is a premium biological filtration media designed to naturally lower nitrate levels in aquariums. By creating the ideal conditions for anaerobic bacteria, it delivers consistent nitrate control, improves water quality, and supports a healthier aquatic environment. A must-have for reef keepers and freshwater aquarists battling persistent nitrate issues.
