The Red Sea ReefRun controller allows you to create your unique Feed scenario by switching selected pumps off or run at different intensities at different times for different durations.
The ReefRun Dual Controller offers great value as it can run both the REEFER DC Skimmer & ReefRun DC Pump (or two ReefRun DC Pumps) at the same time!
The controller is sold separately, enabling hobbyists to purchase one controller for 2 devices and save significantly, while enabling you to reduce your inventory requirements.
