API Nitra-Zorb Treats 210L — Resin media to absorb harmful nitrogenous compounds from freshwater aquariums up to 210 litres
API Nitra-Zorb (SKU: BE5) is a rechargeable ion-exchange resin media specifically designed to absorb harmful nitrogenous compounds—including toxic ammonia, nitrite, and nitrate—from freshwater aquariums up to 210 litres.
API NITRA-ZORB is a convenient, ready-to-use filtration media pouch designed to remove harmful toxins such as ammonia, nitrite, and nitrate from freshwater aquariums. Made from a combination of natural and synthetic ion-exchange resins, it helps maintain a safe and healthy environment for your fish. By pulling nitrogen compounds directly out of the water column, Nitra-Zorb protects fish from toxic spikes during tank cycling or overstocking emergencies, and can be recharged repeatedly using simple aquarium salt solutions.
