The inlet water from the aquarium is pumped into the filter by means of the bypass of the main pump or an additional feed pump. The water flows through the filter from the bottom to the top. The pollutants can bind to the zeolite material and bacteria settle on the surface.
To prevent the filter from becoming clogged and reducing performance, the system should be flushed with air every day. An air pump connected to a timer pumps air into the filter for a few minutes, creating strong turbulence. This mechanical movement loosens excess bacteria, which is removed by the filter's drain.
For high nutrient aquariums: direct the drain from the filter to the suction side of the skimmer.
For low nutrient aquariums: direct the filter effluent directly to the suction side of the recirculation pump. Supplemental feeding with coral and/or bacteria supplements may be useful.
