More From Seachem
Seachem Denitrate removes nitrates, nitrites, ammonia, and organics from both fresh and marine water. The high porosity of denitrate supports the proliferation of both aerobic and anaerobic bacteria that further remove these toxic aquarium by products. Even when exhausted as an organic adsorbent, denitrate continues to be an excellent support for the biological filter and does not have to be removed.

For best results, denitrate should be placed to assure the flow of water through it, such as in a canister filter. Flow rate should not exceed 200 L per hour. It is best to rinse off dust before use. Once denitrate 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 denitrate treats about 100-200 L, depending on initial nitrate concentration and the current biological load. Enough should be used to remove nitrate 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.
