De*Nitrate

Seachem


	Excellent way to remove nitrates
	Great assistant to your biological filter
	Does not require a special denitrifying filter

Description

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.

Tech Notes

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. 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.
