Dr.Tim's One & Only Live Nitrifying Bacteria for saltwater tanks is widely used throughout the hobby and can be used to help prevent common issues with new tanks while helping stabilize existing tanks. Dr. Tim is considered to be one of the premier authorities on marine nitrifying bacteria in open and closed systems. One & Only contains millions of live nitrifying bacteria that will help quickly establish a biological filter in your aquarium allowing you to add fish almost immediately.
- New Tanks
- After Water Changes
- Adding New Fish
- After Treatments
Using Dr.Tim's One & Only is very simple. You should first make sure that your tank is dechlorinated which is critical. If you do find the presence of chlorine, you will need to use a dechlorinator that does not contain aldehydes which can be harmful to the bacteria you will be adding. Turn off any protein skimmers or UV sterilizers and keep them off for up to 48 hours after the addition of One & Only Bacteria.
Shake the bottle very well; the liquid should not be clear. If the liquid is clear, you have more shaking to do! Pour the recommended dose directly onto your biological filter media for the best results. If you do not have a dedicated biofilter, you can just pour dose directly into your aquarium water.
For New Tanks
Add Dr.Tim's One & Only to dechlorinated water after the aquarium has reached the proper temperature, and any filtration components are checked and functioning properly. Once One & Only is added to the tank, fish should be introduced within 24 hours. Without fish, no organic waste is generated, which the bacteria require. If you are not ready to add fish, you can add small amounts of ammonia to the water.
It is recommended to use Dr.Tim's Ammonium Chloride Solution to produce ammonia for the bacteria to consume and convert. Ammonium Chloride will let you cycle your aquarium without having to add a sacrificial fish or any foods giving you complete control of how your tank cycles.
Temperature Sensitive - We recommend shipping Dr.Tim's One & Only when outside temperatures range from 40°F to 80°F. In the middle of hot summer or cold winter months we highly encourage expedited shipping methods.
Refrigeration not required - Never freeze or store in temperature over 95°F - Stable for up to 6 months at room temperatures and up to 1 year at temperatures ranging 40°F to 50°F.
Recommended for aquariums with a salinity over 10ppt or 1.007sg

Fish after 5 days By John on 1/7/2020John would recommend this product to a friendIt does what it says it does. I wouldn’t go without it when starting a new tank.
Did absolutely nothing for me By Greg on 12/2/2019Greg wouldn't recommend this product to a friendI made the decision after extensive research to use this product for cycling my new 360 gallon tank. Around 420 gallons total water volume with sump. After nearly one week of adding just under $200 worth of this product, two of the 16 oz bottles, and dosing ammonia as directed...... I have had zero change in ammonia readings. Dr Tim's basic explanation everywhere is all tanks are different so just wait for ammonia to get to zero. I guess Dr. Tim's just can't guarantee the efficacy of the bacteria in each bottle. It simply is not doing anything and I wish it were possible to get a refund from BRS on this product.
Save your money By J on 9/22/2019J wouldn't recommend this product to a friendHi-
This is a complete waste of $100. He is a Dr of stalled cycles. Seriously, there has to be some level of refund for this fraud.
Product works great By tim on 8/13/2019tim would recommend this product to a frienddosed with dr tims ammonia, 150g completely cycled in about 14-15 days. it did take about 7-8 days before you start to see the ammonia levels steadily go down....then nitrates
Dr. Tim's had no effect By Austin on 3/1/2019Austin wouldn't recommend this product to a friendI bought this product to perform an accelerated cycle on my tank. I used in conjunction with their ammonium chloride solution at 2 ppm and in five days there was zero change in my ammonia, nitrites, or nitrates (2ppm, 0ppm, and 0ppm respectively). Today I added turbostart at a ratio of 1oz:25g and within six hours have seen a decrease in ammonia by ~.5ppm and an increase in nitrites by ~.5ppm. I will never buy this product again and definitely recommend Turbostart as an alternative.
Works wonders By Cody on 11/4/2018Cody would recommend this product to a friendworks very well, I will always use for tank start ups
Good stiff By Chad on 9/1/2018Chad would recommend this product to a friendI decided to try it out and after a week the tanks ready for fish.
Works Everytime By Tom on 1/30/2018Tom would recommend this product to a friendI used this when I set up my 100 gallon and when I set up my 250 gallon.... Wife was stressed but fish were not. Proven to work and makes set up worry free.
It just works By Joseph on 8/13/2017Joseph would recommend this product to a friendPut this in my tank after I had my rock in and 1 fish. I seen the nitrate and nitrite numbers drop over night. The ammonia bacteria are there but they take a bit longer to catch up to the others. Overall would recommmend this product over some of the others out there...this stuff is real and it just works
Awesome product By Drew on 6/24/2017Drew would recommend this product to a friendThis product really works. I know allot of people will disagree, but you can literally setup a tank with this stuff and have soft corals within a week. Used it several times. Glad to see BRS has started carrying it
Does this come with something to feed the bacteria of you don't add fish right away?
Can this be used on freshwater?
Hope this helps!
Why do some bottles say use one cupful and some say two capsules ( same size bottles ).
It is possible that the manufacturer changed the dosing instructions, but we recommend dosing what the bottle you have says. Have a great day!
Does the kit come with ammonia? TIA
