The first step in setting up a healthy aquarium is to establish a biological filter. A biological filter is a natural filtering system consisting of helpful bacterial colonies that, through a cycling process, convert pollutants in water to harmless nitrate. Nitrate is nitrogen, therefore this cycling process is also referred to as the nitrogen cycle, or cycling a tank.
