NITRATE REMOVER 4L Seachem

de nitrate Seachem 4 L – Biological Denitrifying Media

de❊nitrate is a natural porous material whose pore geometry allows the simultaneous development of aerobic and anaerobic bacteria.

It enables the gradual elimination of nitrates through biological denitrification, without the risk of hydrogen sulfide production unlike sulfur-based media.

Operating Principle

The outer layers of the media promote aerobic nitrification by consuming ammonia and nitrites.

As water penetrates the core of the media, oxygen is depleted, creating an anaerobic environment conducive to denitrifying bacteria responsible for the transformation of nitrates.

This function is similar to that of live rocks, but its efficiency is increased by the forced passage of water through the media.

Main Features

Flow Rate and Efficiency

At a high flow rate, above 380 L per hour, de❊nitrate functions primarily as aerobic nitrification support.

At a slow flow rate, below 190 L per hour, it acts simultaneously as aerobic media and anaerobic denitrifying media.

An excessively high flow rate prevents the formation of anaerobic zones and limits nitrate removal.

Usage Instructions

Place de❊nitrate in a cartridge filter, filtration module, housing filter, or sump compartment ensuring direct water passage.

The flow rate should not exceed 200 liters per hour.

For higher flow rates, the use of Matrix or Pond Matrix is recommended.

Rinse the media lightly before use to remove dust.

Dosage and Performance

After a few days of use, nitrates generally stabilize around 4 to 5 mg/L.

If nitrates are initially very high, a preliminary water change is recommended to bring them below 20 mg/L.

Lifespan

de❊nitrate is a biological media and does not deplete chemically.

Its effectiveness may only decrease if the pores are clogged by sediments.

The use of mechanical pre-filtration significantly extends its lifespan.
