LD-2 Solid Surface Leak Detection Probe

Neptune Systems LD-2 Leak Detection Probe safeguards your aquarium investment by identifying water leaks, overflows, and spills before they cause damage. This full-size sensor pairs with the FMM Module and Apex Controller to deliver instant notifications through Apex Fusion when moisture is detected. The weighted, flat-bottom design sits securely on hard surfaces—flooring, cabinet bases, sump stands, and skimmer lids—making it ideal for comprehensive coverage in high-risk areas. Perfect for monitoring under tanks, inside cabinetry, around RO or ATO systems, and equipment zones. Compatible exclusively with the FMM Module. For tight spaces or carpet installations, the LD-1 Low-Profile alternative may suit your setup better.
