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, de*nitrate? continues to be an excellent support for the biological filter and does not have to be removed. This product is sold by volume. Cited weight is minimal weight.
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 200 L (50 gallons*) per hour. If higher flow rates are unavoidable, use Matrix? or Pond Matrix?. It is best to rinse off dust before use. 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. Each 250 mL of de*nitrate? treats about 50?100 L (12?25 gallons*), 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.
