API Nitra-Zorb 210g (Size 6)
API NITRA-ZORB is a ready-to-use filter media pouch that can be added to your filter to remove ammonia, nitrite, and nitrate. NITRA-ZORB is made of natural and synthetic ion-exchange resins that selectively remove toxins from freshwater aquariums. NITRA-ZORB is completely phosphate-free and can be reused after recharging.
Rinse pouch under tap water. Place pouch in path of water flow in the aquarium filter. For a new aquarium or when ammonia or nitrite is detected: recharge every 5 days for the first month, and 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 20ppm (mg/L) or less. Replace pouch after 2 months.
To recharge, dissolve 4 tablespoons (80 g) of API® AQUARIUM SALT in 8 oz. (240 ml) of warm tap water. Soak pouch for 2 hours, then rinse lightly in tap water. When not in use, store pouch in recharging solution.
