Neptune Systems LD-2 Leak Detector
Neptune Systems LD-2 Aquarium Leak Detection Sensor
Safeguard your tank setup with the Neptune Systems LD-2 Leak Detection Sensor, engineered and designed specifically for aquarium leak detection on hard surfaces like concrete, tile, and hardwood. It plugs in and connects directly to your Neptune Apex system to provide you with live real-time alerts before minor drips can become major disasters.
How the Neptune Systems LD-2 Leak Detection Sensor Prevents Aquarium Damage
This aquarium leak detector works on virtually any solid flooring surface, ensuring your stand, flooring, and surrounding area stay safe from unexpected water intrusion. Its weighted body prevents shifting, making it an ideal solution for precision detection.
-
Detects leaks on hard surfaces: wood, cement, and tiles
-
Weighted design prevents probe movement
-
Integrates with Neptune Apex via the FMM Module
-
Instant alerts help reduce equipment or flooring damage
Smart Protection with the Neptune Systems LD-2 Leak Detection Sensor
Don’t leave leak detection to chance. Pairing your Apex Controller with this smart sensor ensures fast detection where it matters.
-
Easily plugs into the FMM (Fluid Monitoring Module)
-
Sends real-time alerts directly to your Apex dashboard
-
Works with other Neptune sensors for complete monitoring
Note: This model works with the FMM, not the older ALD module.
Expand Your Leak Coverage for Peace of Mind
Solid coverage means using more than one sensor. To protect your reef tank system, position multiple LD-2 detectors both inside and outside your aquarium stand.
Suggested sensor placement:
-
Two LD-2 sensors under your sump or inside the stand
-
Two additional sensors outside the cabinet to catch overflow or plumbing failure
-
Ideal for sump-based reef tanks or systems with external plumbing

Commonly Asked Questions About the Neptune Systems LD-2 Leak Detection Sensor
Q: How many Neptune Systems LD-2 sensors should I use?
A:For optimal aquarium leak detection, we recommend using four LD-2 sensors: two inside the stand and two outside.
Q:Will this sensor work with the older ALD module?
A: No. The LD-2 only works with the newer FMM (Fluid Monitoring Module) from Neptune Systems.
Q: What surfaces can the LD-2 detect water on?
A: It detects leaks on hard, flat surfaces like wood, tile, cement, or vinyl. It is not designed for carpet.
Q: Does the LD-2 sensor require its own power supply?
A: No separate power supply is needed. It draws power from the FMM module via the Aquabus connection.
Q; Can I connect multiple LD-2 sensors to one FMM?
A; Yes. You can connect up to four sensors per FMM, giving you complete perimeter coverage.
