Choose the size best suited for your tank:

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.

Worked well

6/12/2013 By: Joseph from Seattle.

First I tried to do a fishless cycle using Tetra SafeStart. After waiting a month with no progress, I decided to try Dr Tim's One and Only. It started to work right away and the tank was fully cycled in 10 days. I will use it first next time.

IT WORKS

Had my new 125 gallon tank going through a fishless cycle. About the end of the first week my other 125 blew a seam and started leaking bad. Ordered "One & Only", dosed the new tank and transferred all my Africans from my original tank (21 fish total). Bottom line is, IT WORKS! No fish losses to date. Finally a product from a Doctor that knows. Many thanks. Ordered another bottle to spike my tank currently being repaired.

Really works

After reading the reviews, I decided to give this a shot. I'm so glad that I did. Within 3 days, my tank was completely cycled! When I start up my bigger tank, I am going to use this product again! Thanks so much Dr. Tim!

Great Product

This product greatly accelerated my fishless cycle. It was amazing how fast my tank processed ammonia once added.

Very happy

My first bottle of this was bought from a buyer on Amazon, and when it arrived to me it was clear it was mistreated, either by the seller, or during shipping. It didn't work properly, and after talking with customer support here, I decided to try again. This time, from this site, using the climate controlled package. After using it, and the ammonium chloride, my tank was completely cycled in 4 days. I recommend the product, and would purchase again.

	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.

	Great Product
	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.

	Mr.
	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.

	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.

	Great 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!

	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.

	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.

	Fishless Cycle
	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.
