Description
Neptune LD-3 Optical Multi-Surface Leak Sensor
The Neptune LD-3 Optical Multi-Surface Leak Sensor is a leak detection sensor that picks up water spillage on a wide range of surfaces, helping you catch a problem before it becomes a disaster. It suits reef and aquarium keepers who run a Neptune Apex controller and want dependable leak detection around the tank, sump or equipment area.
Key Benefits
- Alerts you to water spillage so you can take corrective action before a small leak turns into a major problem.
- Uses optical sensor technology, which is more reliable than analog counterparts.
- Epoxy-coated and corrosion-resistant, so it keeps working after repeated contact with saltwater.
- Reusable: it can be used again after contact with water.
- Does not react to metallic surfaces, so there are no more false alarms.
- Versatile: it can be placed almost anywhere you need leak protection.
- Weighted to stay flat where you put it.
How the LD-3 Improves on the LD-2
The LD-3 is a significant step up from its analog predecessor, the LD-2 Solid Surface Leak Detection Probe. The LD-2 uses conductive strips to detect fluid leaks on the surfaces around your aquarium. The LD-3 uses optical sensor technology instead, which gives it two distinct advantages.
- Reusable and corrosion-resistant: the conductive strips of the LD-2 are prone to corrosion from contact with saltwater. The LD-3's epoxy-coated optical sensors keep providing long-lasting leak detection after repeated contact with saltwater, with no risk of corrosion. The sensor can be reused after contact with water.
- Multi-surface use with no false alarms: the LD-2's conductive strips can sometimes trigger a false alarm on metallic surfaces. With its optical sensor, the LD-3 can be used on any hard surface material, including metal and epoxied cement, without triggering false alarms.
How to Use
- Place the sensor flat on the hard surface where you want to watch for water spillage. Its weighted design helps it stay in position.
- Connect it to the FMM port so it can communicate with your Neptune Apex controller.
Suitable For
- Detecting water spillage on hard surfaces, including metal and epoxied cement.
- Saltwater setups, where repeated contact with saltwater will not corrode the epoxy-coated sensor.
- Aquarium owners who want an early warning of leaks around the tank.
Compatibility
- Connects to the FMM port to communicate with Neptune Apex controllers.

Frequently Asked Questions
Can the LD-3 be used with saltwater?
Yes. Its epoxy-coated optical sensors are corrosion-resistant and keep working after repeated contact with saltwater, with no risk of corrosion.
Will it give false alarms on metal surfaces?
No. The optical sensor does not react to metallic surfaces. It can be used on any hard surface, including metal and epoxied cement, without triggering false alarms.
Can I reuse the sensor after it gets wet?
Yes. The LD-3 can be reused after contact with water.
How is the LD-3 different from the LD-2?
The LD-2 uses conductive strips, which can corrode in saltwater and sometimes cause false alarms on metal. The LD-3 uses an epoxy-coated optical sensor, so it is corrosion-resistant, reusable and suitable for metallic surfaces.
What does it connect to?
It connects to the FMM port to communicate with Neptune Apex controllers.
Where can I place it?
Almost anywhere you want to detect water spillage on a hard surface. The weighted design helps it stay flat.
