Feel free to message me with any questions. The ApexEL has built-in WiFi, Temperature, pH, monitoring and much more! Set reminders, log testing and dosing information, and access your tank from anywhere with Apex Fusion! Just as powerful as the flagship Neptune Systems Apex Controller but at a much more affordable price. The ApexEL is a great entry into gaining full control over your tank, giving you everything you need to get up and running.The ApexEL forgoes a few of the included features that are included with the standard Apex model, like salinity monitoring, ORP monitoring, and variable speed ports, but they can easily be added with Neptune Systems accessory modules. Included WiFi lets you now connect to the internet even easier. With the Fusion Cloud interface, everything is easier from calibrating probes to customizing outlets. Fusion gives you the ability to monitor and control your Apex from anywhere in the world. The Neptune Systems EnergyBar 832 is 100% compatible with the ApexEL, with more robust outlets, individual LEDs show the status of each outlet, per outlet power consumption monitoring. An added bonus to the EB832 is the addition of 1Link ports for accessories like the DOS and WAV pump that can now connect directly to the EnergyBar 832 saving room and eliminate messy cords keeping your tank's equipment looking perfect.
