The Apex controller is by far one of the most advance dedicated aquarium controllers on the market today. The wide variety of controllability with the Apex controllers and their easy to use cloud interface makes it a perfect option for a fully automated reef tank. The seven module limit will cover most tanks that do not need every bell and whistle, but may want leak detection, salinity, or any other of the many modules that Neptune has available.
