API NITRA-ZORB Pouch filtration media is a ready-to-use pouch that can be added to your filter to remove ammonia, nitrite, and nitrate.
NITRA-ZORB filtration media is made of natural and synthetic ion-exchange resins that selectively remove toxins from freshwater aquariums. NITRA-ZORB filtration media is completely phosphate-free and can be reused after recharging.
Contents: 1 Large size 6 pouch sufficient to treat 210L water.
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.
What are the dimensions of API NITRA-ZORB™ filtration media bags?
The actual pouch is 7 x 7 inches square, but because of the media, the final dimensions are 7 x 6.5 inches.
You will find that the pouch sits nicely in one of the baskets of canister filters. All of the size 6 pouches (PHOS-ZORB™ filtration media, NITRA-ZORB filtration media, BIO-CHEM ZORB™ filtration media, ACTIVATED CARBON, etc.) will be this size.
This pouch does not have any stiffness to it, and may easily be placed in the back of a hang-on-back filter, or other sizes of a canister filter. If the filter is very small, cut open the pouch and use as much as needed in a small filter sock.
Does API NITRA-ZORB™ filtration media replace other media?
API NITRA-ZORB filtration media should not fully replace other media; it is for temporary use only.
How is this product different from API BIO-CHEM ZORB™ filtration media, API PHOS-ZORB™ filtration media, etc.? What makes one a good choice over the other?

Use API NITRA-ZORB filtration media if these levels consistently spike.
Use API BIO-CHEM ZORB filtration media works to remove more general aquarium pollutants, such as colors, odors, heavy metals, and toxic gases.
API PHOS-ZORB filtration media specifically targets phosphate and silicate in aquarium water.
