A3 Apex Jr Aquarium Controller System

The A3 Apex Jr transforms aquarium management by automating the monitoring tasks that keep your reef thriving. This entry-level controller tracks temperature, pH, and water level while detecting leaks—giving you real-time alerts before minor issues escalate. The included temperature, pH, and leak detection sensors provide comprehensive coverage straight out of the box, while two AquaBus ports let you expand with additional Neptune modules as your setup evolves. Control everything remotely via Apex Fusion, a free cloud platform accessible from anywhere, and receive instant notifications if parameters drift beyond safe ranges. Built-in Wi-Fi connectivity means you're never disconnected from your tank's health. Perfect for aquarists seeking reliable, worry-free monitoring without complexity, the A3 Apex Jr combines essential functionality with room to grow. Australian-distributed with local support and AU power supply included.
