The optical leak sensor is worth its weight in gold because ultimately a leaking aquarium is the worst possible scenario for any tank owner. You can set multiple alarms for any water depth you like and even trigger your return pump to slow down or turn off should the water level get too low. You can use this LLS in a variety of ways around your tank but perhaps the most valuable application will be monitoring the water level in your sump or filtration chambers. The LLS is the most advanced liquid level monitor to date and essentially acts like a ruler that gives you real-time measurements of the water's depth. The new sensors connect to the base unit via any one of the new fluid monitoring ports.

Instead of the previously included salinity probe, Neptune Systems now includes two brand-new sensors that expand the monitoring power without taking away from the system's capabilities. Just like the upgrades to the head unit, Neptune Systems looked to the reefing community to understand what features hobbyists value most. It's the same finish that we saw on the SKY LED unit and gives the unit a premium look and feel.
APEX AQUARIUM CONTROLLER PRO
To physically differentiate the A3 Pro base unit, it's coated with a rubberized soft-touch finish. The A3 Pro base unit still includes the same variable speed/dimming ports, AquaBus ports, switch connection, probe ports (ORP/pH, Temperature & Salinity), ethernet connection, and auxiliary power port as the previous model so you won't be losing any bit of capability over previous generations. Combined with the new sensors, you now have the ability to monitor the water level and detect a leak right out of the box and you can add flow sensors or optical sensors (sold separately) to suit your specific needs via the new ports! That's right, your Apex base unit can now deliver an audible alarm to notify you right away when something needs attention on the tank. This resulted in the addition of four fluid monitoring sensor ports and a built-in audible alarm!

What's New on the A3 Apex Pro? Upgraded Base Unit with Audible Alarm & New Portsīy listening to hobbyists and using the data available via Apex Fusion, Neptune Systems configured the A3 Apex Pro base unit to include the most valuable probe ports according to its userbase.
