SeaChem De-Nitrate removes nitrates, nitrites, ammonia, and organics from both fresh and marine water. The high porosity of De-Nitrate supports the proliferation of both aerobic and anaerobic bacteria that further remove these toxic aquarium byproducts.
Even when exhausted as an organic adsorbent, SeaChem De-Nitrate continues to be an excellent support for the biological filter and does not have to be removed.
Flow rate should not exceed 50 gallons per hour!
