The pond boss Floating Fountain with White LED Lights is a 3-in-1 pond system that pumps, aerates, and illuminates water in ponds up to 750 gallons. Simply place the floating fountain in your pond and plug it in to create water effects up to 4.6 ft. in height and 2.5 ft. in width. As the sun goes down the automatic dusk-to-dawn sensor turns on the white LED lights and illuminates the water effect, creating a beautiful nighttime glow. Easily and securely position the floating fountain in your pond using the anchor ring. The Floating Fountain with White LED Lights includes an oil-free and energy efficient 400 GPH pump, a float body with an integrated dusk-to-dawn sensor, 12 built-in white LED lights, a waterspray nozzle, and a pumpshield mesh barrier bag to prevent large debris from clogging the pump. To create an even more unique water effect, use nozzle heads from the pond boss Large Nozzle Kit (#52715, not included).
