Abstract: A water circulation apparatus for a swimming pool or hot tub. The water circulation apparatus includes an eyeball connector and an extension hose. The eyeball connector includes a spherical eyeball and a first connector. The extension hose includes a second connector for coupling to the first connector. The eyeball connector fits within a water return line housing in the sidewall of the swimming pool or hot tub. Heated water returned to the pool through the water return line is routed through the eyeball connector into the extension house and is expelled in the pool through the free end of the extension hose. The extension hose may include a weighted free end to ensure that the heated return water is expelled at the bottom of the pool. The weighted free end may include a diffuser.
