Seachem De-nitrate Filter Media

De-nitrate 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 de-nitrate has capacity to trap nitrate, this, as with other nitrate retaining materials, such as certain zeolites and synthetic resins, is quiteLimited and the primary mechanism of nitrate removal is anaerobic.

KEY FEATURES:

Removes nitrates, nitrites, ammonia, and organics
High porosity biological media
Pore size well suited for anaerobic bacteria
No danger of hydrogen sulfide production as with sulfur based media

DIRECTIONS:
For best results, de-nitrate should be placed to assure the flow of water through it, such as in a canister filter, chemical filtration module, or box filter. Flow rate should not exceed 200L (50 USgallons) per hour.
