de❊nitrate Seachem 250 ml – Biomedia for Nitrate Reduction
SEACHEM
Operating Principle
de❊nitrate is a natural porous material whose pore geometry promotes aerobic nitrification in the first few millimeters of depth, followed by anaerobic denitrification at the core of the media. Anaerobic conditions are established due to the material's porosity and the depletion of oxygen on the surface.
Chemical trapping of nitrate is limited. The primary mechanism of nitrate reduction relies on anaerobic bacterial activity.
Key Points
Helps reduce nitrates, nitrites, ammonia, and organic matter.
High porosity biomedia.
Porosity suitable for supporting aerobic and anaerobic bacteria.
No risk of hydrogen sulfide production like sulfur-based media.
Operates in a high-flow aerobic filter.
Operates in aerobic + denitrification at low flow rates.
Installation and Recommended Flow Rate
For best results, place the media to force water through the material (cartridge filter, chemical filtration module, canister filter).
The flow rate through the media should not exceed 200 L/h (50 US gallons/h). If a higher flow rate is unavoidable, use Matrix or Pond Matrix.
Rinse the dust before use.
Expected Results and Sizing
After a few days of use, nitrate concentrations may begin to decrease and gradually stabilize around 4 to 5 mg/L as nitrate, depending on the tank conditions.
The media is not considered "exhausted" as long as nitrates remain under control. Each 500 ml treats about 100 to 200 liters depending on the initial nitrate concentration and biological load. It should be used sufficiently to eliminate nitrate at a rate at least equal to its rate of formation.
If nitrates are initially very high, they should be reduced below 20 mg/L through water changes before starting the media.
Maintenance
de❊nitrate is a biomedia that does not deplete over time, but it may lose effectiveness if the pores become clogged. Pre-filtering the water (sponge, floss, mechanical filtration) extends its operational lifespan.
Capacity
250 ml.
de❊nitrate Seachem 250 ml is a natural porous biomedia designed to support surface nitrification and denitrification at its core, in order to help reduce nitrates, nitrites, ammonia, and organic matter.
