This product has saved my tanks more than once. I know there's a lot of people out there that don't think "live bacteria" products are worth buying since some of them are frauds, but this one does work. I shipped my fish, along with media filter overnight to my new house. After a few days of setting up their new tank, I started seeing a couple of dead shrimp. A quick water test showed signs of ammonia in the tank and I quickly found out that my bacteria from my filter media had not made the trip. I went out and bought some hornwort and this product that day and put it into the tank. The next morning there was no sign of ammonia in sight.

I also used this when I had to medicate a tank and I had a drop in benefical bacteria due to the medicine. I pour some of this into the tank and parameters went back to normal. I would strongly recommend buying more than you need. for example if you are setting up a 20 gallon tank, buy a bottle that is recommended for a 40 gallon tank. It may be a bit more money but I think the results are worth it.

I will ALWAYS use this stuff. I used it to set up my first tank years ago and I used it to set up a new tank about 2 weeks ago. I truly believe this stuff works. Every time I have used this I never had any problems. The one time I didnt use it I had a problem. Perfect for cycling your tank fast, and cycling with fish. My tanks were stablilzed very quickly and I do testds every day, never lost a fish during cycling. Great for water changes too. This stuff definitely works.
