The key to setting up a successful aquarium is to quickly convert the fish waste to a non-toxic form before it builds up to toxic levels. This process is done by nitrifying bacteria. Under normal conditions, it can take 30 to 45 days for these bacteria to become naturally established in a newly set-up aquarium. Unfortunately, during this time period, ammonia and nitrite can increase to levels toxic to fish - a common problem called New Tank Syndrome. Our nitrifying bacteria are the result of the latest scientific research and are used by public aquariums and professionals around the world to control ammonia and nitrite.

Dosage: 10 ml per 40 L of aquarium water.
