API Nitra-Zorb

API NITRA-ZORB 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.The actual pouch is 7 x 7 inches square, but because of the media, the final dimensions are 7 x 6.5 inches. The pouch is sized to sit 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, the pouch can be cut open and partial contents can be put into a small filter sock.API NITRA-ZORB filtration media should
