De-Nitrate

Promote complete nitrification to naturally remove ammonia, nitrites, AND nitrates. Seachem De-Nitrate Nitrate Removal Media feature a unique pore structure similar to live rock that supports both beneficial aerobic and anaerobic bacteria. Ammonia and nitrite removing aerobic nitrification occurs on the outer surface while nitrate removing anaerobic denitrification occurs at the core. Employ low flow rate for natural nitrate removal or use with aquarium filters with higher flow rates for aerobic nitrification.

Great biological filter media for use with saltwater marine aquariums or freshwater aquariums. 2 L/800 grams Seachem De-Nitrate Nitrate Removal Media treats approximately 100 gallons, depending on nitrate levels.

Directions for Use
For best results, Seachem De-Nitrate Nitrate Removal Media should be placed in a canister filter, chemical filtration module, or box filter to ensure proper water flow through it. Flow rate should not exceed 200 L (50 gallons) per hour. It is best to rinse off dust before use.

Once Seachem De-Nitrate Nitrate Removal Media has been in use for several days, nitrate concentrations should start to fall and level off gradually at a concentration of about 4–5 mg/L as nitrate. As long as nitrate concentrations remain under control, the product is not exhausted.

Each 500 mL of Seachem De-Nitrate Nitrate Removal Media treats about 100–200 L (25–50 gallons), depending on initial nitrate concentration and the current biological load. Enough media should be used to remove nitrates at a rate at least as fast as the rate of formation. If very high nitrates are initially present, they should be brought down to less than 20 mg/L with water changes.

General Information
Seachem De-Nitrate Nitrate Removal Media is an economical, natural, porous material with a pore distribution and geometry that promotes both aerobic nitrification 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 Seachem De-Nitrate Nitrate Removal Media has capacity to trap nitrates, 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.
