Description
de*nitrate™
Removes nitrates, nitrites, ammonia, and organics
High porosity biological media
Pore size well suited for anaerobic bacteria
No danger of hydrogen sulfide production as with sulfur based media
De*Nitrate is an economical natural, porous material with a pore distribution and geometry that promotes both nitrification within the first few millimeters of depth and anaerobic denitrification at the core. The material has a high surface area and supports a high density of bacteria.
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 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, 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.
