de*nitrate™ is a high porosity filtration product for the removal and control of nitrate in marine and freshwater aquaria by anaerobic denitrification. It is a porous inorganic solid about 4 mm in diameter. It can be used in a canister filter at slow flow rates or even on the tank bottom as a “live” substrate. It does not require a special denitrifying filter or special culture feedings. It is also helpful in controlling nitrite and ammonia. The surface area characteristics of de*nitrate™ are similar to Matrix™, making de*nitrate™ an effective support for the biological filter. Each liter treats up to 100 gallons. Marine or fresh water use.

Sizes: 1 L, 4 L, 20 L

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 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 liter of de*nitrate™ treats about 50 to 100 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.
