Description

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. DrTim's One & Only 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.

  • 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.

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

It works!!!! I loved how fast it was shipped and how wuickly it arrived. One and only bacteria does work. I used it for my 10Gallon tank. I didn't have high hopes at first but it did magic.

RatingFirst Tank Cycle in Just Over a Week!

1/18/2016 By: from Mississippi USA.

This worked great with the ammonia product. I had never cycled a tank before and this product made it go so quickly! It took just over a week to cycle the tank. I added fish several days ago and water chemistry is still looking great! I'd recommend this to anyone!

Ratinggood product bad price

1/13/2016 By: from dallas.

The product is great and helped my cycle along. Customer service is great and told me how to verify my product was fresh when I had a smeared expiration date. However due to no fault but my own(not enough shopping around $$), I recently found the same exact product by Dr Tim for sale at another fish site for $6.99 for the 4oz bottle and here it is $26.19. Like I said product & cust. service is great. But since the product is being sold elsewhere for 1/4 the price, I feel taken advantage of. Note from DrTim's Aquatics - Beware of super low prices...$6.99 is less than wholesale and the product has probably expired. There are only a couple of authorize on-line site that sell DrTim's Aquatics Product.

Rating Really Suprised!!!
  Had just cycled a 50 gal tank and had 4 - 10 gal to cycle--and was not looking forward to it. Then I heard about "one and only", so I figured it was worth a try. Set up 4 10 gal and added One & Only as directed, and nervously watched if my fish made it. Checked each tank every day and was pleasantly surprised at the results. Would have no problem recommending it. Thanks Dr Tim.

  I like many have been disapointed with bacteria in a bottle products in the past. I tested a few recently. This was the only one that definatly started working within 24 hours. Tanks were clear within 72 hours. I was using a fishless cycle at 85 degrees F.

  Been trying to fishless cycle for a couple of weeks. Used a bottle of the One and Only and my cycle kicked in right away. Ammonia went to zero by the next day, NitItes spiked and went to zero after that. Worked as advertised.

Rating I think it works
  I tried other products that claim to instantly cycle and they did nothing. I used this to speed up the cycle. I quickly got a Nitrite reading and in a few days, an increasing Nitrate level. Not 100% sure if it was the product or nature. Bottom line - it's worth a try!

  I read a lot online about the fishless cycle and was curious about trying it out. I read about the benefits of Dr. Tims One and Only and decided to give it a try on a new 60 gal. tank. I must say, I was not disappointed, 14 days later my tank was fully stocked full of beautiful fish. So far I am 4 days in and have not had any spikes in Ammonia or Nitrite. I am very impressed with the speed in which I was able to cycle my tank. Thanks so much for a great quality product.

  I just set up a system at my office. As I'm not the most patient person in the world, I wasn't excited about a 5-6 week cycling period. I used the product and in 2 weeks had a tank full of Africans and no new-tank issues. Great product!

Rating An excellent product!
  I'm a bacteriologist; so, I'm happy to be able to recommend this product because it always has worked very well for me. I think it's a good example of "truth-in-advertising," as long as it's stored for optimal stability in the refrigerator.

Rating Does as promised
  I have used this product twice now when setting up my 125 gallon tanks. Both times I added a good number of fish the next day after adding and had no ammonia spikes in either tank. Thanks Dr Tim for producing a product that actually works as advertised.

  I started the cycle on my 125 gallon tank only 8 days ago. It is already cycled. Ammonia and Nitrite levels at 0.00 after about 20 hours the last 2 days. One and Only is exaclty what Dr. Tim said it would be and just as easy to use. They even sent Ammonia to use free of charge. I will use One and Only from now on.
