ABSTRACT:
A filter system is provided for mounting on an aquarium tank to treat the water in the aquarium. The filter system comprises a plurality of filter chambers, each containing a different filter media. The filter chambers serve to filter particulate matter from the aquarium water. A heater is further provided for controlling and maintaining the temperature of the aquarium water. The filter system further includes a dry chamber including a biological medium to support the growth of beneficial bacteria on the medium. A particularly preferred type of media is a plurality of plastic biospheres. The beneficial bacteria serve to biologically treat the aquarium and eliminate ammonia and nitrites from the water. At least one buffering chamber including a buffering medium is provided for buffering the aquarium water and maintaining a predetermined alkalinity level for the water. An air pump serves to pressurize portions of said filter system and aerate the aquarium water.
