Description The CoralBox DCA return pumps are an energy efficient and controllable solution for aquarium return pumps. They run on DC voltage and can be adjusted using the included controller to run as low as 10% power. There are 10 different output settings, which means you can adjust the pump to work with your tank- No valves required! The controller also has a built in feed mode and automatically ramps up to its programmed output when turning back on to eliminate splashing.
