API Nitra-Zorb Aquarium Filter

When left uncorrected, high nitrate in aquarium water can lead to water problems invisible to the eye, poor fish health and a build-up of organic pollutants. It is recommended to test water weekly. API NITRA-ZORB is a filtration media in a pouch format that works to remove harmful toxins, such as ammonia, nitrate, and nitrite, from freshwater aquariums. API NITRA-ZORB reduces the risk of fish loss when starting or maintaining an aquarium. API NITRA-ZORB can be reused after being recharged in a salt solution. Fits most canister filters on the market. Use as directed on product label.

For a new aquarium, or when ammonia or nitrite is detected, recharge every 5 days for the first month, then every 2 weeks for the second month. For an established aquarium, recharge every 2 weeks. When nitrate is detected: recharge every 5 days until nitrate is reduced to 20 ppm (mg/L) or less. Replace pouch after 2 months.
