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.

Good stuff October 5, 2015
Reviewer: Robert McCray from Baytown , TX United States  
Definitely helped the cycle along in a 20 gallon long. It wasn't days... but about 3 weeks instead of 4-6 weeks. However to be fair I live in an area with hard water and high pH. My hardness is around 150 ppm and pH stays around 7.6-7.8. But definitely good product. It is the only one I've used that has caused a bacteria bloom.
