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 bio-filtration 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.
