RAPID CYCLE SPECIALIST
The Blue Shark team has more experience producing and distributing true nitrifying bacteria than anyone else. That’s why Colony is the most used and trusted tank cycling product on Earth.
Colony establishes nitrification in days instead of weeks, because only the aerobic autotrophs found in Colony perform effective bio-filtration of toxic ammonia and nitrite. Having a very slow growth rate, a wait of 6-8 weeks may be required to establish bio-filtration in a new aquarium (aquarium cycling).
Colony effectively speeds up this process by introducing millions of these bacteria all at once.
NITRIFYING BACTERIA: FRESHWATER SPECIES
Nitrosomonas and Nitrobacter are considered true nitrifying bacteria because they directly perform the essential steps of the nitrogen cycle in freshwater aquariums: Nitrosomonas converts toxic ammonia into nitrite, and Nitrobacter then converts nitrite into less harmful nitrate. These bacteria are obligate chemolithotrophs, meaning they derive their energy exclusively from oxidizing inorganic compounds—ammonia and nitrite, respectively—making them uniquely suited for biological filtration in aquatic environments. Blue Shark Colony contains concentrated cultures of these true nitrifiers, which allows for rapid colonization of new aquariums. When introduced, these bacteria quickly establish the biological filtration necessary to process waste, resulting in a much faster cycle compared to relying on natural bacterial growth or other bacterial blends.
In contrast to Nitrosomonas and Nitrobacter, some commercial aquarium products now include “spira” strains (such as Nitrospira), which are also capable of nitrification but are comparatively slower-growing and less efficient under cycling conditions. True nitrifiers like Nitrosomonas and Nitrobacter are superior for rapid cycling because they are adapted to higher ammonia levels and can reproduce quickly in new tanks, making them the preferred choice for Blue Shark.
