Seachem Denitrate
Removes nitrates,nitrites,ammonia, & organics from both fresh & marine water. The high porosity of it supports the proliferation of both aerobic & 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 500 mL of de nitrate™ treats about 100–200 L (25–50 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.
