Neptune Systems ApexEL Aquarium Controller


Out of stock



Introducing the new Neptune Systems ApexEL, the “Entry Level” Apex.

Maintain your aquarium with ease.  The ApexEL monitors key parameters like temperature, pH, and the status of your connected equipment.  Proper monitoring helps reduce the risk of losing your aquatic pets from parameter swings or failed equipment.

At a lower cost than its big brother, the Apex, the ApexEL shares almost all the features of the flagship Apex, with the exception that it does not have built-in ORP, salinity monitoring, or 0-10V ports.

The ApexEL is expandable with modules and probes, if desired in the future.

Wireless Internet-Ready

The ApexEL connects to your network via wire, or, the built in 802.11g/n Wi-Fi.

Easy Setup

Set up tasks and to-do reminders help guide you through configuring everything from temperature control, trouble alerts to your mobile device, and many other common aquarium tasks. With the ApexEL, an aquarium controller no longer requires an advanced degree — you are up and running in 5 EASY STEPS:

  • Mount it to the wall or inside your cabinet
  • Plug in the probes and your equipment
  • Connect it to your home network via wi-fi or cable
  • Run the new Configuration Wizards
  • Get the basics of monitoring and control for your entire tank set up, in less than 15 minutes, with no programming!

Self Contained Monitoring

Every ApexEL has a built-in, completely functional, web server – even when the internet is down.  Your tank will continue to operate without interruption and can still be controlled from a mobile device.

Energy Bar 832 – The ultimate control hub

This eight 120V AC outlet Energy Bar includes an internal 100W 24VDC power supply which feeds three built-in 1LINK ports and two 24VDC accessory ports. Each outlet has independent power monitoring with individual LED indicators that tell you when that outlet is energized.  If the device exceeds the current capability for that individual outlet, the LED will blink rapidly.

**Note – The EnergyBar 832 is for use in North America (USA, Canada, and parts of Mexico) and other locales where the electrical service grid provides 120VAC 60Hz power. In other regions which use 230VAC 50Hz power, APEXel systems are bundled with an EnergyBar 6 equipped with 6 outlets specific to that region (UK,, AU, Universal, or Schuko). EnergyBar 6 models do not include the EB832’s per-outlet power monitoring, 1LINK or DC24 ports, or per-outlet indicator LEDs.

Super Easy Mounting

Both the Apex-EL and the Energy Bar 832 have an innovative attachment system, making them easy to mount and access all connections.  A hinged mount allows the controller to be flipped up to make your connections, and flipped back down, tucking them away therefore making it difficult for water to enter via a cable.
