Rated 5 out of 5 by Will0417 I don't usually do this...
I rarely believe people when they say they have a miracle product... This stuff is amazing! It works exactly as advertised. Within 6 hours, my ammonia spiked to .5 ppm, the next morning it was untraceable.
I also LOVE Foster and Smith for shipping the bottles with a cooling pad to keep the bacteria viable.

While cycling my tank i had just passed the ammonia spike and began the nitrites and nitrates. i decided to give this a shot just to see. the next day i had 0 across the board. i still let it cycle for an extra week to be certain. No cons in my book!!

i added two bottles of the bio spira to my recently cycled tank to ensure a high level of nitrifying bacteria before i introduced my first set of fish to the tank. a week later and no sign of ammonia or nitrites. works well. you can add it once a month and specially when you change filter media to replenish some of the bacteria lost when you change filters.

Rated 5 out of 5 by SHANK great product.
I tried cycling the old fasionway that takes for ever. But thanks to instant ocean BIO- spira, (WOW) cycled my whole tank with one bottle added fish the next day 24 hours later. I added 2 baby ocellarius clowns and one purple fire fish in a quarintine 10 gallon tank. Fish doing great will put them in my main tank in 3 weeks so dont hesitate on BIO-spira............
