Seachem's de*nitrate is a high porosity filtration product for the removal of nitrate in the marine and freshwater aquarium by anaerobic denitrification. It is a porous inorganic solid about 4 mm in diameter and does not require a special denitrifying filter or special culture feedings. It is also helpful in controlling nitrite and ammonia.

Seachem's de-nitrate is an economical, natural, porous material that promotes aerobic nitrification within the first few millimeters of depth and anaerobic denitrification at the core, similarly to live rock in the marine aquarium.
De-nitrate is an excellent media for aerobic nitrification too and can significantly increase the biological filtration capacity of the marine aquarium when added to an area of the sump, a media reactor, or a canister filter. At high flow rates (greater than 378 L per hour), it will function solely as an aerobic filter. At slow flow rates (less than 189 L per hour), it will function as both an aerobic filter and an anaerobic denitrifying filter.
It is recommended for best results to rinse off dust before use.
For best results, De-nitrate should be placed to assure the flow of water through it, such as in a media reactor or canister filter, chemical filtration module, or box filter. Flow rate should not exceed 200 L per hour if nitrate reduction is desired.
Once De-nitrate 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.
500 mL of De-nitrate will treat about 100–200 L, depending on initial nitrate concentration and the current biological load.
If very high nitrates are initially present, they should first be brought down to less than 20 mg/L with water changes.
