Neptune Systems A3 Apex Pro System

The Apex Ecosphere

Designed to reduce hassle and increase success, the A3 Apex Pro delivers comprehensive control over aquarium systems. Monitor key parameters, automate critical functions, and receive alerts when something goes wrong. Track testing, schedule maintenance, and manage your tank from anywhere using Apex Fusion — Neptune Systems’ free cloud platform.

The built-in Wi-Fi or Ethernet connection allows seamless access to Apex Fusion from virtually any device. Customise your dashboard, automate equipment functions, and view real-time graphs and alerts. Fusion’s web-based design means there’s no need for manual software updates or complex installations.

A3 Apex Pro Base Unit

The A3 Apex Pro is Neptune Systems’ most advanced monitoring and control system. It includes:

• 4x FMM ports (for fluid monitoring sensors)

• 2x pH/ORP probe ports

• 1x Salinity probe port

• 1x Temperature port

• 4x 0–10V variable outputs

• 6x digital inputs

• 2x Aquabus ports

• Soft-touch housing with integrated audible alarm

• Wi-Fi and Ethernet connectivity

Liquid Level Sensor (LLS)

Unlike traditional float or contact sensors, the LLS provides continuous real-time water depth readings in both centimetres and inches. Ideal for use in sumps, ATO containers, dosing vessels, and mixing stations. Track evaporation, consumption, or dosing accuracy over time. Use Fusion to set alerts or trigger actions based on liquid level changes.

LD-3 Optical Multi-Surface Leak Detection Sensor

The LD-3 uses corrosion-resistant optical sensors rather than conductive strips. Key advantages:

• Reusable after exposure to saltwater

• Suitable for use on a wide range of surfaces, including metal and epoxy

• Reduced false alarms compared to analogue models

• Detects leaks early to prevent damage

Lab-Grade Double Junction Probes

Includes probes for temperature, pH, and ORP monitoring. These double-junction probes offer improved stability and require less frequent calibration. The Apex Fusion app guides you through the calibration process automatically.

Backward Compatibility

The A3 Apex Pro is fully compatible with older Neptune Systems components, including legacy modules, energy bars, and accessories.
