    The Apex Jr features two AquaBus ports that will allow you to connect to additional modules and accessories to continue building out your control system. Want to add Salinity monitoring? Just connect a PM2 module. Need Dissolved O2 monitoring? Simply add a PM3. How about control and monitoring of pumps, lights, and other equipment? Snag an EB832 Power Bar. The opportunities for expansion are endless.

    *NEW* MOS Magnetic Optical Sensor

    The Neptune MOS replaces the previous OS-1-M and features an updated design that fits into tighter spaces and helps to prevent water incursion into the sensor. The MOS plugs into an Apex FMM port and, using reflected infrared light, will signal your Apex when it changes state from being wet to dry or dry to wet. This sensor can be used for constructing your own ATO (auto-top-off), as a high-level warning sensor in your sump, water storage level sensor, and much more. The sensors can be mounted on any type of reservoir that has up to 1/4" thick walls.

    LD-2 Surface Leak Detection Sensor

    Neptune's LD-2 is a full sized leak detection probe perfect for inside your stand, on hard floors, on top of skimmer cups, or any other flat surface where an overflow may cause issues. If water ever touches the sensor, your Apex Controller will be instantly notified so you can take corrective action and avoid disaster.

    Lab Grade, Double Junction Probes

    The Apex system includes high-quality probes for monitoring your tank's temperature and pH. Calibration is a quick and simple process via the app dashboard, which will automatically recognize when your readings have stabilized and letting you know when to move to the next step-- no more guesswork and reading RAW data. In addition, the double junction pH probe will allow your readings to stay more stable without the need to calibrate as often.
