    I'm Floored!!!  This is the real deal - it works fast!
  

*by M***H on Reviewed in the United States on January 22, 2021*

My wife and I set up a new aquarium a month ago.  Because we're not experienced, the fish went in a few days later.We got an API master test kit after learning about the nitrogen cycle.The ammonia was 2ppm (after 3 weeks).  We started started changing water.  It helped a bit on the tests - but the tank just wouldn't move towards cycling at all.The ammonia was at 4ppm when I ordered  Bio-Spira (amazon two-day delivery).Folks, I'm writing this now, 24 hrs after we treated our tank with Bio-Spira.I just tested the water.  Ammonia is 0.  The Nitrites are around 4ppm, and the Nitrates are about 5 ppm.Not 48 hrs ago the nitrites were  0.5ppm, and no nitrates.This stuff works!Edit (1/27/2021):  Ammonia is still 0.  The Nitrites are a bit less (3 ppm) and the the Nitrates are the same.  FYI, I did add more Bio-Spira during a 1/3 water change...that happened a day after my original post.  I'll be adding the remainder of my Bio-Spira today.  Then order more.  This works.  The important part is to keep testing your water!Edit (2/3/2021): My tank is fully cycled.  Using the API master test kit, the Nitrites are gone, the Ammonia is gone.  No fish have died.  They seem quite happy.  My Nitrates were at 10 ppm...I tested the water right before a 1/3 water change.This will be my last edit post.  I just want to let everyone know that, if you are a new aquarium owner, you will save SO much time helping your aquarium (and fish) with this product.  Even after getting fish (like me) this stuff WORKS fast!

    Buy this one ! Seriously!
  

*by T***Y on Reviewed in the United States on February 24, 2020*

Wow so this is the best cycling product out there ! Put some in my 10 gallon 2 days ago and in 2 days I have nitrates already ! Worked ridiculouly fast after trying to use bottle after bottle of seachem stability with absolutely zero luck. Can't believe it worked that fast ! I was struggling for 3 months and this product did what Stability couldn't overnight

    Product has always worked for me!
  

*by M***T on Reviewed in the United States on July 23, 2017*

This product works great, I've used it for 3 brand new tanks. They were a 3gal, a 10gal, and a 20 gal. In all the tanks I had a completed nitrogen cycle with 5 days, usually faster. I use it occasionally when I replace the filter media to supplement any bacteria that may have been lost. But this product works, I've heard people say that the beneficial bacteria can't survive in a "bottle" but these people usually aren't biologists is the slightest, bacteria can go dormant and with marineland's packaging it prolongs their shelf life. I recommend this product all the time and I've never heard anyone complain that it didn't jump start their cycle.
