ABSTRACT:
Apparatus for use in draining, cleaning and refilling an aquarium tank including an elongated flexible hose having first and second opposite ends, a tube including an upper distal end for connection to the first end of the flexible hose, and a lower distal end adapted to be immersed in the aquarium tank such that the lower end may be placed near the bottom of the aquarium tank, a first device attachable to the second end of the flexible hose and for connection to a flowing water source for creating a flow of water from the tank through the tube and the flexible hose, and a grille, defined by a chamber and including a plurality of apertures formed in the walls thereof that are narrower than the width of the gravel particles, the grille and chamber attached to the lower distal end of the tube for contact with the gravel for moving the gravel about the floor of the tank such that the gravel particles are forced by the movement to bump and rub against each other outside the tube to dislodge the sediment and impurities that have gathered therewith, and wherein the sediment and impurities are swept by the water flow through the apertures into the chamber, up the tube and through the hose for discard without the entrance of gravel into the tube or hose.
