The key to setting up a successful aquarium is to quickly convert the fish waste to a non-toxic form. This 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 condition called New Tank Syndrome. One & Only Nitrifying Bacteria accelerates the process so that you can set up a tank immediately.

Use One & Only when setting up a new tank, after a water change, cleaning your filter, when adding new fish and after a disease treatment to control ammonia and nitrite. Use as directed.

  • Instantly create a bio filter
  • Remove toxic ammonia and nitrite, naturally
  • No sulfur or other offensive odors
  • No wait needed
  • 100% natural
