Neptune A3 Apex Pro System (1Link) Controller - Temperature, pH, ORP, Salinity Monitor

The Neptune A3 Apex Pro System is the top-tier offering from Neptune Systems, designed for the most demanding aquarium hobbyists who want comprehensive monitoring, control, and automation right out of the box. It offers the most complete set of features and included probes compared to the standard A3 Apex and the A3 Apex Jr.

The most comprehensive aquarium monitoring and control system in the Neptune
ecosystem. Features advanced liquid level sensors, multi-surface leak detection & four FMM ports. Monitor everything from temperature and pH to exact water depth and individual equipment power consumption, all managed through the Apex Fusion app on any device.

Monitoring with the A3 Apex Pro System:

• Temperature: The A3 Apex Pro comes with a temperature probe for continuous and highly accurate temperature monitoring. This is fundamental for any aquarium, especially reef tanks, and the system can trigger alerts or control heaters/chillers to maintain a stable environment.
• pH: Yes, it includes a lab-grade, double-junction pH probe. This allows for precise, real-time tracking of your tank's pH, a critical parameter for water chemistry and livestock health. The system can provide alerts for out-of-range pH and allows for automation based on pH levels (e.g., controlling a CO2 regulator for a planted tank or a calcium reactor).
• ORP (Oxidation Reduction Potential): The A3 Apex Pro includes an ORP probe. ORP is an indirect measure of water cleanliness and its oxidative capacity. Sudden drops in ORP can indicate issues like decaying organic matter (e.g., a dead fish), allowing you to intervene before a major problem develops.
• Salinity: Yes, the A3 Apex Pro base unit has a dedicated salinity probe port. However, it's important to note that the salinity probe itself is typically NOT included with the A3 Apex Pro system and needs to be purchased separately. While the port is there, you'll still need to buy the conductivity probe. This is a common point of confusion, so be sure to check the specific bundle you're purchasing.

Key Features of the Neptune A3 Apex Pro System:

• 1LINK unit supplied
• A3 Apex Pro Base Unit: This is the brains of the system. It features:
• Built-in Wi-Fi and Ethernet connectivity: Offers flexible options for connecting to your home network.
• 4 FMM Ports: Dedicated ports for connecting fluid monitoring sensors (like the included Liquid Level Sensor and Optical Leak Sensor).
• 2 AquaBus Ports: For expanding the system with additional modules.
• 2 pH/ORP probe ports: Allows for connection of both included probes and potentially another pH or ORP probe if desired.
• 1 Salinity probe port: For connecting the separately purchased salinity probe.
• 1 Temperature probe port: For the included temperature probe.
• Soft-touch finish and new built-in audible alarm.
• Included Fluid Monitoring Sensors:
• New Liquid Level Sensor (LLS): For precise water level monitoring in sumps, ATO reservoirs, dosing containers, etc., enabling highly accurate auto top-off and volume tracking.
• Optical Multi-Surface Leak Detection Sensor (LD-3): A reusable and corrosion-resistant sensor that can be placed on any surface to detect leaks, triggering alerts and automated actions.
• Apex Fusion Cloud Interface: The powerful, free, web-based platform (accessible on any device) allows for:
• Real-time monitoring and graphing of all parameters.
• Intuitive programming and control of all connected equipment.
• Customizable dashboards.
• Real-time alerts via email, text, or push notifications.
• Data logging for analysis and troubleshooting.
• Remote access from anywhere with an internet connection.

Benefits of the A3 Apex Pro:

• Comprehensive Monitoring: Provides a holistic view of your tank's health right out of the box (with the addition of a salinity probe).
• Advanced Control and Automation: Allows for highly sophisticated automation rules based on sensor readings, schedules, and power consumption.
• Disaster Prevention: The extensive monitoring and alert capabilities significantly reduce the risk of catastrophic tank failures.
• Integrated Ecosystem: Seamlessly connects with other Neptune Systems accessories (WAV, DŌS, Trident) via 1LINK and AquaBus, creating a powerful and unified control system.
• Peace of Mind: Knowing your tank is being continuously monitored and can respond to issues provides significant peace of mind for serious aquarists.
