ATM Blue Shark Animal Planet Tanked AAT00414 Colony Sw, 16-Ounce

Isn’t as expensive as the others, and just as good if not better.

Followed the directions on the bottle and my tank was fully cycled when tested three days latter!

Worked well in cycling my new saltwater tank in no time. Added product then added 2 clownfish. They are still doing great and thriving after 2 months. Great product if want to cycle tank fast.

I was having an endless ammonia spike due to a container of food falling into the tank. killed my whole CUC and 3 fish, only 2 clowns remained alive through it, only because i was dosing with ammo-lock every 2 days in hopes of the biofilter eventually kicking in, well it didn't. i tried a couple of other nitrifying bacteria products and nothing worked, even after 50-75% water changes.finally, after my last water change, i dumped in a bottle of ATM, and within 2 days my ammonia dropped to about 4ppm, by the 5th day it was undetectible, i am finally in the final stage of the nitrogen cycle, and after my next water change, all my levels should be perfect. I highly recommend this product!

Been in saltwater for 40 years, many claims by many products. This is the only one I've tried that really works. Bank on it !. New tank, recovering from copper dose, dead biostructure? quick and efficient

I had my doubts originally about this product but took a leap of faith. I cycled my tank in less than a week using ATM colony, live rock, and live sand with RO/DI saltwater. Doubting the results I even contact ATM directly with my water parameters and they confirmed that my tank had cycled. My nitrates are still going down right now but I have to say that I am a believer now and I was a skeptic before. I have also taken my water samples to my local fish store and they confirmed that the tank has successfully cycled. Ignore the old rule of thumb that you have to let your tank cycle for 4-6 weeks because with this stuff you don't have to. I'd recommend it and use it again.

I'm not gonna blame the product but I am gonna blame how its stored and handled this containes live bacteria colonies. This packages arrived so hot i knew they where boiled ! Despite that I put it in my tank and hoped for the best next day comes i test ammonia to find a spike of 3.0 o.o and the next day it shot up to 8.0 and the next day it was so dam high my test tube turned dark blue! The highest is dark green but this turned it dark blue ! My aquarist and I concluded that this bottle contained dead batercia that I poured in to my tank tainting my water thus causing the death of a very young beautiful clown fish i wont be buying bacteria ever! Again from Amazon and k suggest yall dont neither buy it your aquarium store dont be lazy.. i hope my mistake brings you to make the right decision.
