An economical, natural, porous material with a pore distribution and geometry that promotes both aerobic nitrifications within the first few millimeters of depth and anaerobic denitrification at the core. The material has a high surface area and supports a high density of bacteria. Although de nitrate has the capacity to trap nitrate, this, as with other nitrate-retaining materials, such as certain zeolites and synthetic resins, is quite limited and the primary mechanism of nitrate removal is anaerobic.
Product Features
- De nitrate removes nitrate through anaerobic denitrification, primarily occurring at the core of the filter material
- High surface area supports dense bacterial colonization for efficient biological filtration
- Pore structure enables both aerobic nitrification near the surface and anaerobic denitrification in the deeper layers
- Designed to work efficiently in aquarium filter systems to reduce nitrate levels

FAQ
How does Seachem De Nitrate remove nitrate from aquarium water?
Seachem De Nitrate removes nitrate primarily through anaerobic denitrification, which occurs in the core of the filter material. The porous structure supports bacterial activity that converts nitrate into nitrogen gas, which escapes from the system.
Is the nitrate-trapping capacity of De Nitrate effective for long-term use?
The material has limited capacity to physically trap nitrate. Its primary function is anaerobic denitrification, which is more effective and sustainable for long-term nitrate reduction in aquariums.
Can De Nitrate be used in both new and established aquariums?
Yes, De Nitrate is suitable for both new and established aquariums. It integrates well into existing filter systems and supports ongoing biological filtration.

I’ve used this filter in my 55-gallon tank for three months. Nitrate levels dropped from 80 ppm to under 10 ppm. The filter fits well in my hang-on-back system and doesn’t clog easily. The instructions were clear and setup was straightforward.
Theresa Gill –
Good performance in reducing nitrate, especially after a few weeks of consistent use. I noticed a slight drop in water clarity initially, but that improved after a week. Works well with my established fish community.
Matt Slater –
The material is dense and holds up well in my filter. I’ve seen a steady decrease in nitrate over time. It’s a reliable addition to my filtration routine and doesn’t require frequent replacement.
Ruth Mitchell –
It helps reduce nitrate, but the effect is slower than expected. I had to run it for several weeks before seeing noticeable changes. Works fine, but not a quick fix for high nitrate spikes.
