Neptune Apex A3 Pro System

Take total control of your reef system with the Apex Pro A3 — the most advanced controller from Neptune Systems. Designed for coral-keepers who demand high performance, this all-in-one unit monitors temperature, pH, ORP, and more, detects leaks and water level changes, and automates your equipment via the included Energy Bar 832. With full connectivity via WiFi/Ethernet and cloud access through Apex Fusion, you can oversee your system from anywhere. Ideal for aquacultured coral systems (like ours) where precision and stability are everything.
