ABSTRACT:
This invention relates to an internal multi-component accessory for tall aquariums (those whose depth makes the aquatic life inaccessible and cleaning of the inside walls of the aquarium impractical by normal means). The objective of this accessory is to filter the water, clean the inside walls of the aquarium, provide heat and light, while providing for the transfer of air into the aquarium. It is a further objective of this accessory to provide convenient access to all fish and plant life within the aquarium by floating from its position on the bottom of the aquarium to the top bringing up all fish and plant life as well as gravel (filtration medium). The accessory is a plastic container abutted to a sponge between two rigid plastic plates, both of which are designed to conform to the inside of the aquarium. The container holds gravel in its top outer shell while providing a bottom inner core or pocket for trapping air. The sponge with its two plastic plates has a heating and lighting unit in its center.
