One & Only Usage Chart
  • Eliminates new tank syndrome
  • Instantly creates a bio filter
  • Removes toxic ammonia and nitrite, naturally
  • No sulfur or other offensive odors
  • No wait needed
  • 100% natural

Use 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.

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 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.

Good for 6 months at room temperature, 1 year at 50F (10C).
Keep refrigerated for longest shelf life.

Directions for Use:
Minimum dose: 10 ml per 10 gallons of aquarium water.
Cannot be overdosed.

One and Only Works!
This amazing product worked amazing for me both times! I cycled a tank that was empty 3 days ago.... Added fish in 3 days without incident or loss... The fish took to the tank like they had been there for signs of stress and eating immediately. Was I lucky? Perhaps but it worked twice inside of a month on two separate tanks because wee MOVED really unexepectedly as we got full price for our house and set up a second reef at the new house! This stuff is magic darn near! Thanks Dr Tim!

Worked exactly as described in the video. My tank did cloud up a few days into the cycle but I was told to be patient. I was and it cleared up beautifully. Thanks Dr. Tim.

Never cycle without it
This stuff just flat out works. I have now cycled 5 tanks with One and Only and have had great success every time. In my experience I still witnessed a cycle but it was brief (3-4 days) and have not lost a fish. Great product! I will now be using it periodically just to beef up the bio-filter.
