Trusted by public aquariums around the world, Colony true nitrifying bacteria is the standard when it comes to establishing bio-filtration instantly. Before fish can be introduced into the aquarium, bio-filtration must be established to filter out the toxic ammonia and nitrite created by fish waste. ATM’s Colony establishes this biofiltration in days instead of weeks with real, commercial grade nitrifying bacteria. Used by ATM, the #1 aquarium builders in the world, Colony contains real Nitrosomonas and Nitrobacter bacteria, which are specific for the freshwater environment.

Note: Following the instructions for Colony is very crucial to it's performance. The bacteria in Colony are living organisms that require particular operating conditions. Omitting one direction can result in product failure.

Absolutely love this product! By using this product I had a fully cycled 180 gallon aquarium in three days! Would recommend Colony for anyone starting up an aquarium or dealing with mini cycles.

Best products on the market March 30, 2016
Reviewer: Isaac Oberlander from Brooklyn , NY United States  
I have a 65 gallon freshwater aquarium that has crashed a while back and i have spent alot of $$$ to try and get back into cycle. I added 2 additional canister filters, the absolute most expensive bio media and bacteria on the market 6 times the ammount that i would need. But nothing worked. Untill.... i called ATM and the person on who answered the phone was STACEY BLOOD!!! This was the best thing that has happened to me in a while. Mr. Blood has worked with me over the phone and via email for almost 2 months to figure out what was wrong with my water and how i can help it. He was with me along this entire journey untill my tank has finally achieved the bacterial cycle. In all my years i have never received such amazing service on a personal 1 on 1 level. And their products are as amazing as their service. I would absolutely suggest to anyone in the hobby new or old to call ATM with any aquarium related problem big or small, you will be amazed. Thank you so much Stacey and ATM.
