Before fish can be introduced into the aquarium, biofiltration must be established to filter out toxic ammonia and nitrate created by fish waste. ATM's Colony speeds up this process and establishes biofiltration in days instead of weeks. Colony for Freshwater contains Nitrosomonas and Nitrobacter bacteria, which are specific for the freshwater environment. This formula has proven to be the premier instant cycling for all freshwater aquariums.
