Neptune SystemsSKU: LD-2



Leak Detection Probe for solid surfaces  (ALD-P2)

Plug this probe into your ALD and then place it on any surface where you want to detect stray water. Upon contact with water this probe will communicate to your Apex and alerts or other actions can then take place.  Time is so critical when it comes to water on the floor so it is very common to place two of these inside the stand and two outside the stand to have the ultimate protection against a leaky aquarium. The sensor has a wire length of 5 meters. Note: The ALD-P2 will only work with the ALD and cannot be used with the FMM module.

Be notified if there is ever a leak before it turns into a disaster. Connecting the ALD-P2 Leak Detector to the ALD module will allow your Apex Controller to notify you if water ever touches the sensor. There are many applications for leak detectors from water on floor warnings, skimmer cup overflows and much more. 

  • Compatible with ALD
  • Weighted to stay flat
  • Can be placed almost anywhere


The ALD-P2 is a full size leak detection probe that is compatible with the Neptune ALD module only. The full size sensor is great for inside of your stand, on hard floors, ontop of skimmer cups and any other application that a leak, or overflow may cause an issue. If you have carpeting or tight space requirements we suggest using the ALD-P1 Leak Detector Probe.


Note: The LD-2 will only work with the FMM and cannot be used with the ALD module.
