ABSTRACT:
An ecosystem is created in an aquarium using a main tank and a filter tank. The main tank provides a suitable environment for aquatic animals and has a series of tubes along the bottom to distribute incoming water. An outlet near the high water mark of the main tank creates bottom to top circulation. The water is pumped through the filter tank that comprises a carbon filter, a plant and temperature compartment, a bacteria filter, and an aerator compartment. Water from the main tank is withdrawn and processed through each compartment in the filter tank to remove all the impurities harmful to the animals in the main tank by nitrification and photosynthesis. A pump returns the cleaned water to the main tank through an ultraviolet light purifier. Valves on the conduits between the main and filter tanks prevent circulation during repair and maintenance of the filter.
