The Neptune Apex Lite System is the best-value aquarium controller on the market today. Dollar for dollar you will not find a higher-quality controller that gives you more features, is easier to use, or has a larger and more active user base than the Apex.
The Apex Lite System is just like its bigger brother the Apex System. However, the Apex Lite System is the choice for those that want the advanced features of the Apex System but who do not feel that they need a couple of features like the built-in ability to control LED lighting or monitoring an extra pH or ORP probe.
Apex System comes complete with:
-Apex Lite Base Unit
-Energy Bar 8 (or Energy Bar 6)
-Apex Display Module
