This is the color-changing, dynamotor-powered waterfall fountain that imparts visual ambiance to a swimming pool without batteries or an electrical connection. It connects to a pool's return opening with included fittings, placing the fountain above the water's surface just off the pool deck. Incoming water pressure induced by the pool's return pump activates the fountain's dynamotor, which powers both the fountain in an arc reaching 78 3/4" over the water, as well as its array of multicolored LEDs. 17" H x 12" W x 3 1/2" D.
