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.
- Neutralizes ammonia and nitrite spikes naturally
- Establishes instant biofiltration
- Safe for all fish
This formula has proven to be the premier instant cycling for all freshwater aquariums.
Before fish can be introduced into the aquarium, biofiltration must be established to filter out toxic ammonia and nitrate created by fish waste.
