Product details
A3 Apex Jr System – Neptune Systems is an entry-level controller and monitoring base unit for aquarium owners who want to track key tank parameters and build into expanded control later. It’s designed to connect to probes and sensors for ongoing measurements like temperature and pH, monitor water level, and help alert you to leaks—then let you review and manage logs and reminders, with remote access via WiFi. The practical goal is simple: stay on top of routine water quality checks and potential trouble spots before they become problems.

- Helps detect leaks using an LD-2 Leak Detection Floor Sensor with a built-in audible alarm.
