Neptune Systems Apex A3

The A3 Apex is an advanced aquarium controller system that combines monitoring, automation, and safety controls to help you run a reef or marine tank with confidence. It monitors water temperature and pH via included lab‑grade probes, tracks water level and detects leaks via built‑in sensors, and lets you control power to pumps, heaters, lights, and other equipment automatically. With Wi‑Fi/Ethernet connectivity and integration to the cloud interface Apex Fusion, you can receive alerts (on temperature, leaks, power outages etc.) and manage settings remotely. The A3 Apex includes the “Energy Bar” power module which supplies multiple outlets and 24 V accessory ports, making it easy to centralise and control all your tank’s electrical devices.
