ABSTRACT:
An aquarium for fish and other forms of marine life is constructed in the form of a globe symbolic of the planet earth and equipped with a special device for aerating and purifying the water. The unique shape of the aquarium lends itself readily to purification and elimination of sedimentary matter and the aerator-purifier is constructed to aerate the water and at the same time is equipped with filters to filter the water and to remove larger foreign matter, the filters being readily accessible and adapted for easy removal, cleaning and replacement.
