Rapid Cycle Specialist
Your pond’s biological filter is its most important line of defense against toxic fish waste. Colony Pond contains live, commercial-grade nitrifying bacteria that help establish biological filtration in days instead of weeks.
Formulated with freshwater Nitrosomonas and Nitrobacter, Colony supports the natural nitrogen cycle by helping convert ammonia into nitrite, then nitrite into less-harmful nitrate. This makes it an excellent choice for koi ponds, goldfish ponds, ornamental ponds, water gardens, and quarantine systems.finestaquatics.co+1
Use Colony when starting a new pond, adding fish, replacing filter media, restarting a filter, or following medication—any time your pond’s beneficial-bacteria population needs support.
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.
