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 saltwater 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.

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.

Big Cycle
I have a 670g system that I needed to do a cycle fast on. I bought several bottles of the ammonia and one 32oz. Bottle of the bacteria. I used 3/4 of the bacteria and only 2 treatments of the ammonia to get my tank going. 3 days later I added 6 very large fish, all my old inverts, and corals. One more week later I added 4 more large fish, 3 anemones, and 4 shrimp. Tank is still keeping my levels at zero for ammonia and nitrite. Nitrate is barely recordable. Great product, will use again.

" BUY IT "
Hi, i bought the 8 oz. bottle for my 125 gal. tank. I used tap water and prime, dropped in two clown fish on 7-4-2015. Som far things are GREAT!!! This product did just what they said it would do, I have 140 pounds of " LIFE ROCK " in my tank , by the way. I thought it was a little pricy , but because it has worked so well, it would be cheap at any price. I had a question, they wrote me back that same dame day, GREAT people, they really CARE!!

We Love One & Only
We love One & Only! Our incoming fish systems (8 of them) are sterilized after every shipment to mitigate heterotrophic bacteria breaking down medications during future QT runs. After sterilizing we need them back up to accept another shipment post haste, which is where One & Only comes into play.

Works Great!
Using O&O along with the ammonia available i was able to cycle my marine aquarium in about 3 weeks. I will more than likely use this product again if/when i need to cycle a new tank.
