Seachem de*nitrate Fish & Aquatic Filtration Media, 8.5 Oz

Seachem de*nitrate Fish & ; Aquatic Filtration Media For more than 30 years, aquarium hobbyists have turned to Seachem Laboratories for products designed by chemists and biologists. Create a cleaner aquarium water environment with Seachem de*nitrate. This natural, porous material promotes both aerobic nitrification and anaerobic denitrification. With a pore size well suited for anaerobic bacteria, Seachem de*nitrate is an ideal biological filter in drip trays, canister filters, sumps, and box filters. It poses no danger of hydrogen sulfide production. 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 US 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 US 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.
