NITRA-ZORB filtration media is scientifically proven to remove aquarium toxins.
Follow API Easy Care Guide and use NITRA-ZORB when:
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.
We’ve proven how well NITRA-ZORB works in reducing ammonia and nitrite levels! Do you want to know how? Check out the Science Inside article here.
Directions: 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.
* Preorder basis - Take approximately 1.5 - 2 months.
$17.00The HI774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker® HC. These reagents follow the Ascorbic Acid Method in which the reaction between phosphorus and reagents causes a blue tint in the sample. By simply adding the packet of HI774-25 reagent to the sample, the reaction will take place and the HI774 will determine the concentration from the color that is produced. The results will be displayed in ppb of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate.
