Review: Buy it! - My go to for cycling an aquarium. I’ve used other brands to cycle a tank and this by far has cycled my tank the quickest.
Review: Avoid some of the pitfalls of nonscientific saltwater tanks - Saltwater aquarium set up is full of hoodoo vudoo. Some people may want to set up their aquarium over many weeks or months. I've heard it all toss a dead shrimp in the tank and wait for the magic to happen. Hum. That's not my idea of science. I hold a science degree with extensive work in biology and microbiology. My tank was set up with RODI water Carib live sand and rocks as well as dr Tim's nitrogen fixing bacteria. Water salinity and ph all within the appropriate ranges. Temperature was 78. degrees. I tested all aquarium parameters with the master test kit. I added 2 clowns a carpet anemone and some hermit crabs. After acclimation to tank temp and salinity these animals have done extremely well. The clowns and anemone have become acclimated all fish are eating and doing well and all critical tank tests show no dangerous levels of ammonia, nitrite or nitrate. Dr Tim has the correct nitrogen fixing microorganisms specifically for aquariums so does the sand and rock. I do have years of aquarium experience but this is my first saltwater tank. Dr Tim has experience setting up huge commercial aquariums and has a PHD in microbiology. You are free to choose hoodoo vudoo or science. I'll take science every time.

## Questions & Answers

**Q: Should i use this product on a new tank with live sand and carib sea life rock?**
A: Yes, this product jumpstarts the system bio-load. With the live sand and the rock your system should be cycled in under a weeks time you'll need a source of ammonia as well.

**Q: The title is for "one & only" but the images show "waste away". which is correct?**
A: You have to select the one and only in the tab below then it will change to the correct one also pick the ounce size you want

**Q: is this a complete kit that comes with an ammonia source?**
A: This is only the bacteria.  Amazon does sell a kit with ammonia and bacteria for 18/19 bucks.

**Q: Is this product the same with One and Only bacteria? I'm buying One and Only so I'm not sure if I still need to get this one.**
A: never have used one and only .. but waste away worked great for me .

### ⭐⭐⭐⭐⭐ Seems to have done what it said it does.
*by I***E on May 2, 2019*

Cycled a 120g tank with Caribsea Hawaiian Sand, media balls (the ceramic ones) and dry man-made liverock. Used the ammonia by the same brand to get up to about 4ppm. By day 2 I had a massive nitrite spike and Ammonia was just trace. Added more ammonia day 3 to get to 2ppm. Added microbacter7 on day 3 as well. Nitrite spike did last about 5 days reading off the charts before it went to 0. Refugium was up and running when the Nitrites became readable (API test). I’m about 10 days in and am running at 0 ammonia, 0 nitrite, and about 10-20 nitrate.” With Chaeto growing nicely. I normally cycle tanks with gulf live rock and it takes about 4-5 days to get a stable tank setup. I’ve never really had the ups and downs of new tank syndrome. Will be interesting to see if I get the hair/bacteria/cyano blooms over the next few months.
