peace of mind

Aloha, if you're reading this review, you're already an apex addict. These units with the ALD module, will give you peace of mind knowing that if there is a leak, you can shut down the pumps that will minimize the event and receive email/text message that there's a leak. The half star off is for 2 issues. First, as others have noted, they are pretty much a disposable item. If wetted with salt water, the fasteners and metal components will be unreliable due to corrosion. To me, this isn't a big deal, they will have worked and replacement cost is minimal compared to the possible damage. Secondly, it is just a dry switch. If you have a breakout box, you can ditch the cat5 connector, use a multimeter to determine which 2 of the 5 wires are active, and connect to the breakout box.....I was actually using the breakout box with wired metal plates to do the same thing before I decided it looked too getto for my system....REEF ON AND PROPAGATE

I will never have a reef tank without one. After I had to take down a tank years ago due to a skimmer overflowing into my stand, I vowed that I would never have an issue with water overflowing again! I have had two of these around my tank for a year now and they work very well. They are very sensitive and have only been used once (thankfully) when my skimmer cup became too full and was leaking a little bit into the tank. It shut it off right away and let me know about the issue. No harm done. This is an invaluable tool if you have an Apex!

Neptune apex Leak detector

This is another quality item from Neptune. I sleep easier know knowing that if I experience a leak I'm alerted right away. I've had a few leaks related to adjusting my skimmer which has damaged my wood floor. It's no fun walking into your house and seeing the water under your stereo cabinet. I purchased my Neptune Apex system about about a year ago and this device makes me love it just that much more. Thanks Neptune Apex.
