Neptune A3 Apex Pro Aquarium Controller System

The Neptune Systems A3 Apex Pro is the ultimate aquarium controller, offering comprehensive monitoring (pH, ORP, Temp, precise liquid levels) and control. Features 1LINK integration, advanced sensors (LLS, LD-3), lab-grade probes, and full Apex Fusion access for discerning aquarists.

Neptune Systems A3 Apex Pro System – The Ultimate Experience in Aquarium Monitoring & Control

Empowering Discerning Aquarists with Critical Monitoring and Precision Control.

The Neptune Systems A3 Apex Pro System represents the pinnacle of aquarium automation, offering the most comprehensive monitoring and control experience within the Neptune ecosystem. Designed for the discerning aquarist, this professional-grade system provides unparalleled insights into your tank’s health and enables precise control over all critical parameters.

Unrivalled Control and Monitoring:
The A3 Apex Pro System is headlined by its advanced base unit, boasting sophisticated monitoring capabilities that extend beyond the ordinary. Track vital parameters from temperature, pH, and ORP to exact water depth with the new Liquid Level Sensor, and monitor individual equipment power consumption.

What’s Included in the A3 Apex PRO Bundle:

A3 Apex Pro Base Unit: The intelligent core of the system.
It features an array of ports, including:

  • 4 FMM Ports:
  • 4-Channels 0-10V Variable Output: For precise dimming or control of compatible devices like lights and pumps.
  • 6 Switch Digital Inputs: For integrating various switch-based sensors or devices.
  • 2 AquaBus Ports: For seamless connection of additional Apex modules and accessories.
  • 2 pH/ORP Probe Ports: For continuous monitoring of acidity/alkalinity and oxidation-reduction potential.
  • 1 Salinity Probe Port: (Salinity probe sold separately) For precise measurement of salt concentration.
  • 1 Temperature Probe Port: For accurate and continuous temperature monitoring.
  • Dual Connectivity: Both Wi-Fi and Ethernet compatible for flexible and reliable network connection.
  • Soft-Touch Finish: A modern, tactile design.
  • Built-in Audible Alarm: Provides immediate sound alerts for critical issues.

Complete Power and Control with the 1LINK Module (Australian System):
The Australian version of the A3 Apex Pro System is powered by the included 1LINK Module, which acts as the central power and control hub. This revolutionary module not only powers the Apex unit but also offers integrated power and communication for Neptune Systems’ 1LINK devices, simplifying your wiring and setup.

  • Three 1LINK Ports: Connect devices like DOS, COR 15 Intelligent Return Pump, and Trident Water Analyzer directly to your Apex system.
  • Integrated 120W Power Supply: Provides ample power for all connected 1LINK devices, streamlining your setup.
  • Simplified Cabling: Reduces clutter by combining power and communication into a single, elegant cable per device.
  • Plug-and-Play Installation: Ensures effortless setup with one-click connections.
  • Apex Compatibility: Works seamlessly with all current Apex controllers.

You can even set up custom controls to turn certain outlets on/off if one of the other parameters falls outside of your safe zone. For example, if your tank’s temperature rises too high, your Apex can automatically activate a cooling fan or cut power to a potentially malfunctioning heater.
The automation possibilities are virtually endless!

Lab-Grade Probes:

The Apex Pro system includes high-quality probes for monitoring your tank’s temperature, pH and ORP (Oxidation-Reduction Potential).
Calibration is a quick and simple process via the Apex Fusion app dashboard, which automatically recognizes stable readings, eliminating guesswork.

Temperature Probe:

Keeping a stable and consistent temperature in the aquarium is paramount to the health of your inhabitants. Monitoring temperature and especially temperature changes throughout the day is mission critical. Having a quality temperature monitoring solution that also alerts you to over or under temperature situations is a must for a successful aquarium.

pH Probe:

Keeping pH stable is critically important to healthy coral in a reef aquarium. A stable pH is also less stressful for all the aquarium’s inhabitants.
Monitoring pH not only allows you to tune in desirable parameter stability but also serves as an important warning system to warn you of negative chemistry changes.

ORP Probe:

Oxidation Reduction Potential (ORP) is the measurement of water cleanliness. ORP level indirectly indicates the ability of beneficial bacteria in the aquarium to reduce contaminants like nitrates, ammonia ECT. Ultimately it is in part a measure of the electrical charge available to break down these contaminants.
Sudden changes in ORP are often reflective of organically bad things happening the aquarium. If a fish passes or too much food is available, the change in ORP can prove to be a much needed signal to investigate or take action.

LLS Liquid Level Sensor:

This first-of-its-kind continuous vertical sensor accurately identifies the exact depth of liquid in both inches and centimetres. Gain unparalleled insight into changes in evaporation, consumption, and dosing levels within sumps, ATO reservoirs, AIO tanks, dosing containers, and mixing stations. Set custom alerts or automate actions based on precise liquid level changes, with measurements viewable in digital and animated readouts in the app.

LD-3 Optical Multi-Surface Leak Sensor:

Reusable and Corrosion-Resistant: Unlike conductive sensors, the LD-3’s epoxy-coated optical sensors can be reused after contact with water, offering long-lasting leak detection with no risk of corrosion, even with saltwater exposure.

Multi-Surface Applications with No False Alarms: Optical sensor technology allows effective use on any surface material, including metal and epoxied cement, without triggering false alarms, ensuring reliable protection for your home and floors.


The APEX FUSION App – Seamless Cloud-Based Connectivity:

Apex Fusion is a free, cloud-based service that grants you remote access to your Apex from anywhere in the world. This user-friendly platform allows for effortless monitoring of your aquarium’s vital parameters. With intuitive features like drag-and-drop customization for dashboards, easy-to-use task functions for setting up new equipment, and real-time alerts delivered directly to your device, Apex Fusion ensures that maintaining optimal aquarium conditions is hassle-free, efficient, and always within your control.

Wireless Internet-Ready!
When possible we recommend the superior reliability of a wired network connection for your Apex Pro, however when that’s not possible your Apex is perfectly capable connected on WiFi.

Future-Proof Expandability:
The Apex Controller System is not merely a purchase; it’s a future-proof investment in your aquarium’s long-term health and your peace of mind. Designed with backward compatibility and easy expandability, your Apex system can grow with your needs.
Want to add salinity monitoring? Simply connect a PM2 module and Conductivity Probe.
Considering automatic testing of your tank’s Calcium, Alkalinity, and Magnesium levels? The Trident is the perfect addition. With dozens of optional add-on devices and modules, you can tailor your Apex system precisely to your exact requirements, adapting to any advancements or changes in your aquascape.
