Blue Shark Colony Rapid Cycle 236ml

Blue Shark Colony Rapid Cycle is a concentrated live nitrifying bacteria solution formulated to quickly establish biological filtration in marine aquariums. It contains marine strains such as Nitrococcus and Nitrosococcus that convert toxic ammonia and nitrite into less harmful nitrate, allowing tanks to cycle in days rather than weeks. Ideal for new aquariums, after major water changes, or following filter/media swaps, it helps maintain a stable, safe environment for fish and invertebrates. The product should be dosed according to aquarium volume, with good aeration and minimal disturbance to the beneficial bacteria to achieve optimal results.
