Seachem - De Nitrate - Nitrate Remover

Seachem 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.

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

De Nitrate is also an excellent media for aerobic nitrification and it makes an ideal biological filter in drip trays, canister filters, sumps, or even box filters.

At high flow rates (greater than 100 US gallons per hour), it will function solely as an aerobic filter.

At slow flow rates (less than 50 US gallons per hour), it will function as both an aerobic filter and an anaerobic denitrifying filter.
