In a new aquarium, harmful ammonia and nitrite build up from fish waste, often resulting in fish loss or new tank syndrome. The nitrifying bacteria in API Quick Start quickly consume ammonia and nitrite by immediately establishing the biological filter to help prevent new tank syndrome. The unique, patented bacteria in Quick Start also help to maintain an active biological filter in an established aquarium. Does not require refrigeration.
Use API Quick Start when starting a new aquarium, adding new fish, changing water, changing filter media, after medicating or whenever ammonia or nitrite are detected.
