API Quick Start Freshwater and Saltwater Aquarium Nitrifying Bacteria
In a new aquarium, harmful ammonia and nitrite build up from fish waste, often resulting in fish loss or “new tank syndrome”. The unique, patented nitrifying bacteria in API QUICK START are scientifically proven to quickly consume ammonia and nitrite to help prevent fish loss. API QUICK START allows immediate addition of fish to a new freshwater or saltwater aquarium as it immediately starts the aquarium cycle. This treatment also helps to maintain an active biological filter in an established aquarium for healthy water conditions. API QUICK START contains live, nitrifying bacteria.

I used API Quick Start when setting up my new freshwater tank. The ammonia levels dropped within a day after adding the bacteria. My fish stayed healthy and active from the start. No fish deaths or stress signs. Highly recommended for new tank setups.
Robert Johnston –
It worked well in my saltwater tank too. I added it right after setting up the system and noticed a significant improvement in water quality within a few days. The fish seemed more active and less stressed.
