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.

  • Did too good of a job By jsbull on 1/19/2016

    I 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.
  • Works but not in 24hrs By Tom on 1/9/2016

    I used this product to cycle a 57 gallon tank. It does speed up cycling tremendously. I finished cycling in about a week. I used ammonia to start then added this product, ammonia levels dropped to 0 within 24 hrs then nitrites appeared. Nitrites took much longer to drop but with in 7-9 days both ammonia and nitrites were at 0 and ready for fish. I'd say definitely don't add fish right ways like it says, just monitor your parameters and keep adding Pure ammonia. You will check one day and both ammonia and nitrites will be at zero. And your ready for fish.
  • Saved my fish in hospital tank By Justin on 9/23/2015

    Had to get a hospital tank up and running quickly. Was managing ammonia via water changes and was a constant battle. Gave this stuff a shot and boy took my ammonia to nitrite and then nitrate in <24 hours. Things to consider, the more the better works best for me when I dose a 8 oz bottle into about 30 gallons, also check the expiration date on the bottle, the fresher the better. This will not take 120 gallons of water dosed with 2-5 ppm ammonia to zero overnight, but if added in the proper quantities can dramatically accelerate the cycling of the tank. Highly recommend if you need a QT or hospital tank cycled ASAP. Worked wonders and probably saved that fish as the constant battle to keep the ammonia low I'm sure added stress.
  • CUT CYCLE TIME By ALEX on 9/15/2015

    CUT CYCLE TIME IN HALF
  • Good Product By Jeremy on 6/16/2015

    This is the second time I used the product and can't complain. I have seen no ill effects on my tanks so i will continue to use it.
  • Amazing By friartuck on 6/7/2014

    This stuff is my new god. Used a little bit to help speed up the curing of live rock- totally cycled in about a week. Used the rest in my 50g start up- totally did the trick. Incredible.
  • Epic By Mathew on 5/26/2014

    Reduce the start time!
  • Good Product By LiNuo on 6/10/2013

    I had high levels of ammonia (1ppm) and decided to add this product. The following day I tested the water and the ammonia went down drastically to .1ppm.
    I only had 2 clown fish in my system and unfortunately I lost 1 in the process. My nitrites went off the roof the following day from 0-5 ppm. I guess I should of used this products without fish.
    Works as advertised!
  • Must Have.. By Tyler S. on 3/27/2013

    I use this on every new tank! It speeds up the cycle and being able to add fish. Recommend this to everyone.
  • Works Great By Gary on 3/19/2013

    I added the bottle to my Biocube 29 and it only took two weeks to cycle my tank starting with dry rock and dry sand.
  • Worked By Ross on 1/4/2013

    Had no issues with this product, did exactly as advertised.
  • fast cycle By Bill on 11/1/2012

    Fish ready nearly right away. Wish I would have had a QT setup sooner so I could be adding fish now!
