LD-2 Solid Surface Leak Detection Probe - Be notified if there is ever a leak before it turns into a disaster. Connecting the LD-2 Leak Detector to the FMM module will allow your Apex Controller to notify you if water ever touches the sensor. The LD-2 is a full size leak detection probe that is compatible with the Neptune FMM module only, great for inside of your stand, on hard floors, on top of skimmer cups, and any other application that a leak, or overflow may cause an issue. The LD-2 will only work with the FMM and cannot be used with the ALD module.
