DrTim's Aquatics Saltwater One & Only 2 oz...

The product does exactly what it is supposed to do. I had to tear down a reef tank after I had a big die off due to a power failure, and this is just what I needed. This is a very good product. I have used this product in the past for setting up new saltwater and brackish aquariums.

This product is great. Easy to use very clear and precise instructions. To be used to ammonia to go along with it and they sell that too. Would recommend to a friend or anybody else.

seems to work .

I have been using this bottle bacteria to start up 10+ tanks over the years and probably will continue to do so. I think what many people get wrong is either (A) they think the cycle is instant or (B) they follow the chart to a T. You dont add the second drops of ammonium chloride until ammonia reads 0.4 or less and you dont do water changes unless pH drops below 7. Ive had tanks cycle in 9 days and I have had tanks take up to a month to cycle. Just be patient. Nothing comes fast or easy in this hobby

I used this with the Dr tims ammonia to cycle my tank, it cycled in about a week. I had dry rock in my tank with live sand and it cycled very quickly, i have also been using it when i add new fish to the tank as a precaution and have not had anything but 0 ammonia, 0 nitrites and very low nitrates while using this. I know you can use this and add a fish or two immediately in bigger tanks (>75 gallons) and you can probably do it with one fish in smaller tanks but after researching a lot, i used the ammonia in my nuvo 38 just to be safe, after i cycled the tank i added 3 tiny Blue/Green Chromis with another half bottle just to be safe and saw NO change in my water parameters. The stuff works! My degree is in Biology specifically micro biology and I went to a school that has a big fish health biology program so a lot of my classes were related to fish, after researching Dr Tims and reading his actual peer reviewed research on the website and based on my own experience with it, I would HIGHLY recommend this if you are using dry rock when starting a tank. Also, i have yet to have a diatom bloom in this tank, which is a huge bonus. I had read from other reviewers that they didn't have the bloom and i didn't believe it. The biggest thing though is read the directions and follow them!
