Seachem De-nitrate 100 ml Bagged will effectively remove nitrate. It's 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 de-nitrate has 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.

• de-nitrate (Seachem Web Site)
• Nitrate control
• 100 mL of de-nitrate treats about 5–10 gallons, depending on initial nitrate concentration and the current biological load. The de-nitrate is bagged and should be placed in a canister filter, chemical filtration module, or box filter with less than a 50 gph pump flow.
