As trusted by public aquariums around the world such as Sydney and Melbourne, Colony true nitrifying bacteria’s claim to fame is through results. ATM Colony cycles aquariums really, really, really fast. That why fish keepers call it “The Month Buster”.
Aquarium cycling, defined as the process of establishing bio-filtration for natural ammonia and nitrite removal, is essential to a successful aquarium.
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 comes in two different formulas which are used to introduce fish immediately in ATM’s own custom installations. Colony for Freshwater contains real Nitrosomonas and Nitrobacter bacteria, which are specific for the freshwater environment. Colony for Marine contains two different real strains specific for marine systems: Nitrococcus and Nitrosococcus. These formulas have proven time and again to be the champions of instant cycling on site at ATM installations.

“True” Nitrifying Bacteria: The Ones You Want
Some products claim to establish bio-filtration by utilizing anaerobic, facultative anaerobic, and heterotrophic bacteria. While some of these bacteria can perform a negligible amount of nitrification under certain conditions as a secondary energy source, they are not to be confused with “true” nitrifying bacteria which utilize ammonia and nitrite as a primary energy source.
