The Neptune Apex A3 System PRO is a top-tier aquarium monitoring and automation platform designed for serious freshwater and marine setups. As the flagship model in the A3 series, it offers the most complete set of ports, sensors, and control features available directly from the base unit.
The Apex A3 PRO acts as the central control hub of your aquarium, continuously monitoring critical parameters such as temperature, pH, salinity, and water level, while managing connected equipment through an integrated, cloud-connected interface.
Key Capabilities
- Real-time monitoring and alerts – detect issues such as heater failure, pH instability, or leaks before they escalate
- Automated responses – control pumps, lighting, dosing, and top-off systems based on live data
- Equipment monitoring – track performance and power usage of connected devices
- Remote access – manage and monitor your aquarium from anywhere
What Sets the PRO Version Apart
- Includes 4 Fluid Monitoring Module ports for expanded system integration
- Four 0–10V variable output channels for precise control of compatible equipment
- Hardwired Ethernet connection in addition to WiFi for enhanced reliability
- Advanced liquid level monitoring and optical multi-surface leak detection included as standard
While both the standard A3 Apex System and the PRO version share the same core platform and compatibility with modules and accessories, the PRO model delivers the most comprehensive feature set out of the box, making it ideal for advanced or large-scale systems.
