The Red Sea ReefSense Leak Detector provides early warning of water escaping from an aquarium, sump, plumbing system, top-off reservoir or reverse-osmosis system.

The digital detector connects to ReefControl Lite or Pro and reports its status through the ReefBeat app. It is designed to detect water ranging from low-mineral reverse-osmosis water to saltwater, making it suitable for placement around multiple parts of the aquarium system.

Multiple Leak Detectors can be connected to a compatible ReefControl controller, subject to the number of available ReefSense ports. This allows separate monitoring beneath the aquarium, near external filtration equipment, beside an RO reservoir or in other areas where water damage is a concern.

When ReefControl is connected to ReefControl Power, a detected leak can be used to switch off selected equipment automatically.
