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.

Still waiting for cycle
Four weeks into a fishless cycle using Dr. Tim's one and only bacteria and ammonia product as directed. Still not cycled. Ammonia level has stayed steady at 2ppm for weeks without adding more.

Very impressive
I had an urgent need to set up a new tank: my platys had bred so enthusiastically that I was facing a Mathusian crisis in my main tank. So, I set up a 10g tank and transferred many of the juveniles to it to grow a bit before taking them to my LFS. They'd be overcrowded as adults, but I figured juveniles wouldn't be much of a problem, as I was using another company's product to establish a biological filter. I was wrong. A few days after movign the juveniles, and having followed the other company's instructions to the letter, I tested ammonia and found a reading of 0.5. Danger signal. So I bought a 2 oz. bottle of "One and Only" and added it to the tank. Tested the next day, the ammonia read 0.25. The day after that: 0.0. I'm very impressed. Near as I can tell, Dr. Tim's really does establish a sufficient biological filter right away. I'll be sure to use it again when I set up my next tank.

One and Only(Freshwater)
I LOVE this stuff! It has help me keep my water parameters in check after doing water changes and after serving my filters. I add a capful per 10 gallons and my ammonia, nitrite, and nitrates have always been in check. My fish are very active and I am very happy! The only thing I have to say is that this product is rather expensive and something you don't want to waste. Other than that I now tell people about Dr. Tims and why they should use it! Thank you Dr. Tim!

Excellent Bacterial Source
One & Only is the only Freshwater Aquarium Bacteria Supplement that I could find that actually works. Bought several others that only had dead cesspool sludge, waste of time and money.
