- BIO-Spira - Instant Ocean
Why does BRS recommend this?
Bulk Reef Supply sees great value in Instant Ocean Bio-Spira, because it has been a staple in the hobby for many years and with the reason is that it simply works. It is a very effective source of live nitrifying bacteria, for new tanks, quarantine tanks, water changes, or any time the biological load may increase in a saltwater system.
Use BIO-Spira in newly setup saltwater aquariums to make it fish safe. Live nitrifying bacteria reduces fish loss in marine aquariums due to ammonia and nitrite toxicity. BIO-Spira can also be used after a water change, when adding new fish, or after medicating your saltwater aquarium. See shipping restrictions in Full Details.
- 100 mL size is good for 30 gallon tanks
- 250 mL size is good for 75 gallon tanks
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.

An excellent trusted product! By Samich Saweeg Batta on 1/21/2018
Samich Saweeg Batta would recommend this product to a friendI have used this product for years in all my new tank builds. For a reef tank the cycle is done in 14 days or less. Fish only (QT tanks)- instantaneously.
Thanks Dr. Tim for creating this product while working at IO. -

Wow, just wow!!! By Ant on 3/14/2017
Ant 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 3/10/2017
Garrett 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 3/8/2017
Smo 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 12/11/2016
Fernando 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 5/6/2016
Mike would recommend this product to a friendFastest cycle that I've had yet!
How soon after can I put corals in tank?
Question posted on Jun 8, 2017 11:08:00 AM
While the bacterial supplement will establish beneficial bacteria in your system, this does not provide a complete or stable ecosystem conducive to good coral health. Typically we would recommend allowing for 2-3 months at minimum to allow the tank to mature prior to adding more sensitive livestock.
Happy reefing!

Is this shipped with ice-packs or something to keep it cool, or is it simply a bottle in a box that will sit in a plane/delivery truck?
Question posted on Apr 26, 2016 7:42:00 PM
Great question!
These bottles are not shipped cooled rather just in factory packaging. The Dormant bacteria will survive most any trip.

Do you need to do a major water change after cycling the tank with bio spira?
Question posted on Mar 18, 2016 5:20:00 AM
Great question!
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!

I am starting a quarantine tank. The plan is just to use RO/DI saltwater mix...not water from my DT. I was wondering do I just add the mixed saltwater and then add this stuff and it should start the cycle...then do periodic water changes. My quarantine is being used for freshly bought fish and then putting them into my DT. My DT is still cycling, hence why I'm not using that water, so when its done the fish will already be ready to drop into the DT tank if that makes sense.
Question posted on Apr 27, 2016 11:07:00 PM
Correct! The Bio-spira will allow for instant addition of fish as it add the bacteria for you. Keeping up with testing and not adding too many fish immediately is a crucial step. Feel free to let us know if you have any further questions!

I am starting a new tank with BRS Fiji dry rock. There was a lot of dead/ decaying matter on the rock in received, so I gave the rock and acid bath. Now when using this product to aid in the cycle do you add it before there is any ammonia present or vice versa? The bacteria in this needs ammonia to feed and live on, right?

Great question!
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!

I started a new tank with the Nuvo Fusion 20 starter kit. I used bio spira and it's been about 10 days. I have been ghost feeding and I also put a piece of shrimp in the tank for about 5 days in the beginning. Never really detected much ammonia and very little nitrite. In the past 5 days or so I have been getting more and more Nitrate. Does this mean that the tank is cycled? Should I do a water change now or wait for the Nitrate level to go down to zero? It's at 50 now based on the red sea test kit. Thanks.

Hey there! It sounds like you are on the right path! Water changes will definitely help reduce those nitrates. :-)

Does the whole bottle have to be used at once? I want to keep this on hand for using when i set up my quarantine but i see on the bottle it says use entire contents at once?
Question posted on Dec 29, 2017 10:01:00 PM
Thanks for reaching out to us!
Sorry, but the entire bottle must be used. Have a great day.
