BIO-Spira is an essential water conditioner for setting up new marine aquariums. Contains patented and patent-pending live nitrifying bacteria that detoxify ammonia and nitrite. BIO-Spira accelerates the establishment of the bacteria necessary for successful biological filtration to prevent fish loss due to new tank syndrome. In just minutes after adding BIO-Spira to your saltwater aquarium, you can introduce your fish without exposure to dangerous levels of ammonia or nitrite. BIO-Spira can also be used after a water change, when adding new fish, or after medicating your saltwater aquarium. New shelf-stable formula requires no refrigeration.
This is the perfect companion product for dry rock if you are looking to speed up the tank cycle. BRS has had very good success using it in our own tanks and recommend this product to anyone starting a new tank.
- 100 mL size is good for 30 gallon tanks

Wow, just wow!!! By Ant on 3/14/2017Ant would recommend this product to a friendI cannot believe I waited months to cycle my previous tank when I couldve just bought this stuff and been done with it in a week. Yeah, that's right, I said "a week". It was actually shorter than that. I overdosed Bio Spira for my size tank then started ammonia dosing immediately after. I also added a new Marinepure plate. It took 3 days to clear out 3ppm of ammonia. The second dose of ammonia took 2 days to clear out 3ppm. And the third dose..............you guessed it, cleared it out in under 24 hours. After the 3rd dose I started testing nitrite and the numbers were off the chart. I was thinking "knew it was too good to be true". Gave it another day and tested again and my head almost exploded when it came back 0ppm. The nitrite test only goes up to 5ppm and it was well beyond that for sure so I just couldnt believe it. Tested 3 more times with the same readings. This stuff is amazing. From now on I'm using this stuff with Marinepure bio blocks for every new tank build. A million stars!!!!!!!
Cycles in less than 5 days By Garrett on 3/10/2017Garrett would recommend this product to a friendI've used this on all tanks but my first...The first took 4 weeks to cycle...all the rest took 5 days. Also, I notice a cleaner tank using this, I suspect it has nitrate fixing bacteria, as well!
Must for setting up a sterile QT/HT By Smo on 3/8/2017Smo would recommend this product to a friendUsed it following both copper treatment and tank transfer method for new fish during quarantine in two different tanks. No ammonia spike, barely detectable nitrites, which quickly went to zero in a newly set up quarantine tanks.
Awesome! By Fernando on 12/11/2016Fernando would recommend this product to a friendThis product is no joke. It really works. I like the fact that this helped my water perams get stable again. After the tank crashed due to someone who poured something in the tank (made ammonia present was about 10ppm) killed everything in the tank. Did a giant water change, poured this sucker in, and bam, water has been stable for a couple of weeks now. So, yes I do recommend this to anyone who's tank has crashed or is starting up a new tank. It's very beneficial to add this!
Used it with BRS Reef Saver Rock! By Mike on 5/6/2016Mike would recommend this product to a friendFastest cycle that I've had yet!
Bio By Kristy on 5/6/2016Kristy would recommend this product to a friendThis is good stuff.
2.5 weeks, done. By JackKingCole on 5/5/2016JackKingCole would recommend this product to a friendIt all depends, do you run BB or have sand? How much rock? whats your filtration? IME, sand with a mechanical filtration and will cycle using BIO SPIRA in about 2.5 weeks. That does not mean add livestock, people,. It means pay attention to your parameters. Titrate, titrate, titrate, then add slowly. Good product for sure. Thank you, Dr. Tim for developing this.
Instant Ocean BIO-Spira By jerry on 5/5/2016jerry would recommend this product to a friendUse this all the time.Never failed .Works great.
Works as advertised By William on 4/29/2016William would recommend this product to a friendI was starting a new tank, 90 gallons of total volume, with dry rock and live sand. I after I filled the tank up I added the BioSpira by itself and added some fish food and shrimp to the tank. I had an ammonia spike over about a 36 hour period and I have been reading 0 ammonia ever since. I have recently added 5 green chromis, two peppermint shrimp from my other tank and some snails, and I am still reading 0 ammonia, 0 nitrites, and 0 nitrates.
I saw this product getting bashed on the forums, I almost passed it up, glad I didn't. It works just like it says. I don't believe I would have put my fish in during that first few days but I certainly helped the cycling process tremendously. I believe the bottle says 24 hours or something like that but it was more like two days for the ammonia to show up and dissipate. I still waited about 2-1/2 to 3 weeks before adding my fish.
This product isn't a complete cycling solution, and testing is necessary. I am very pleased with it.
It's good stuff. By Millz on 4/17/2016Millz would recommend this product to a friendI used this to speed up my cycling process of my Pukani live rocks. Rocks were ready, ammonia free cured and cycled in about 30 days.

Did too good of a job By jsbull on 1/19/2016jsbull would recommend this product to a friendI read so much trash talk on this product on forums that I almost didn't get it, but decided it couldn't hurt.
I set up a 96 gallon display tank with a 20 gallon sump. I decided to go dry rock to get a clean start. The day I filled it with water, I dosed it with Biospira, then added 2 raw table shrimp to get the nitrogen cycle started.
Where I went wrong is that I waited a week to test for ammonia. Test = 0. Nitrites = 0. Nitrates = 0. I thought, "What the heck?!?!" Well, 4 more shrimp and 3 weeks later and I still couldn't get a blip on the tests. I had my LFS test the water. Same outcome.
I finally added a couple of fish, figuring the cycle would start and I'd be scrambling to save them. However, there was never a single issue. I have since added a total of 5 fish, a dozen corals and an anemone. Levels are still 0 across the board and it's been 2 months.
The reality is that this cycled my tank in 1 week. So fast that I didn't see the cycle and woke up in a panic in the middle of the night several times.
I highly recommend this product, but suggest you test from day 1.

These bottles are not shipped cooled rather just in factory packaging. The Dormant bacteria will survive most any trip.
You should not need to perform a water change unless certain elements such as Nitrate are present in large amounts. Feel free to let us know if you have any further questions!
The Bio spira will help to keep up with the curing process by converting the waste through the nitrogen cycle. Feel free to let us know if you have any further questions!
This product will treat a 75 gallon tank with 250 mL. This means 3.3 mL per gallon.
