Colony Nitrifyin Bacteria M 8oz

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 Marine (M) is made specifically for saltwater and reef systems. It delivers live, saltwater-specific strains of nitrifying bacteria (Nitrosococcus and Nitrococcus) that establish bio-filtration in days instead of weeks. Only the aerobic autotrophs found in Colony perform effective bio-filtration of toxic ammonia and nitrite. On their own these bacteria grow very slowly, so cycling a new marine aquarium naturally can take 6 to 8 weeks. Colony speeds this up by introducing millions of live bacteria all at once, so you can add livestock sooner while keeping ammonia and nitrite under control. Use it to cycle a new saltwater tank, or to reinforce an established biofilter after water changes, cleaning, adding livestock, medicating, or changing filter media.
