API Nitra-Zorb 7.4oz

Help reduce nitrate in your aquarium and create conditions for fish to thrive with API Nitra-Zorb Filtration Media. Fish waste, uneaten food, plant refuse and other organic matter increase nitrate, nitrite and ammonia levels which is harmful to fish. These conditions cause gill damage, stress, illness and even lead to fish loss. API's Nitra-Zorb Filtration Media reduces this risk of fish loss with high-quality filtration media that targets and removes nitrate, nitrite and ammonia from freshwater aquariums. It is composed of natural and synthetic ion-exchange resins in a convenient pouch and can be recharged. Use during aquarium set up or whenever nitrate or ammonia levels are above 20 ppm.
