- Optical sensor for water level monitoring and leak detection with MOS and LD-2 sensors
- View trends and history inside the Apex Fusion dashboard
Protection & Alerts
- Automatically turn outlets on or off based on water parameters, sensors, or even time/day of the week
- Email and/or push notifications when something needs your attention
- Built-in audible alarm for immediate local alerts
Control & Expansion
- Control Neptune Systems equipment like DOS and COR pumps, Trident testers, and more
- Also compatible with select non-Neptune equipment from top brands like EcoTech Marine, AquaIllumination, Sicce, and Kessil
- Backwards compatible with legacy Apex modules
Inside the A3 Apex

A low-profile optical sensor that detects water
- Simple on/off water level detection
- Use in sumps, ATO reservoirs, AIO tanks, dosing containers, mixing stations
- Set alerts or actions when level is below or reaches the sensor
Detects leaks on most flat surfaces.
- Warning to help prevent damage to your aquarium or home
- Place next to the aquarium, in the stand, or where ever leaks may occur
- Weighted to help the sensor stay flat
Monitor temperature and pH right out of the box.
- Includes temperature and pH probes
- Double-junction pH probe helps maintain stable readings
- Easy, guided calibration steps in Apex Fusion.
The Apex ecosystem is designed to grow with your tank. Start with monitoring and control, then add Neptune accessories over time to build a system that matches your goals.
For Example:
- Add automated testing with the Trident ACM or Trident NP
- Set up automated dosing or water changes with the DOS QuietDrive
- Add additional modules to add a salinity or ORP probe
If you already own Apex modules, energy bars, or other compatible accessories, they can work with the A3 Apex controllers.
- Compatible with both existing and legacy Apex modules and accessories
Apex Fusion is a web-based command center for monitoring, alerts, and automation. Customize the dashboard with drag-and-drop tiles and check in from nearly any device.
Set reminders, log testing and dosing information, and keep tabs on your aquarium from anywhere.
- Web-based interface with dashboards, graphs, and tiles
- Alerts help you respond to small issues before they become big problems
- Apex Fusion app is compatible with iOS and Android devices
