Neptune Systems Apex A3 Pro

The Neptune Systems Apex A3 Pro is a comprehensive, all‑in‑one aquarium controller system that gives you full automation, monitoring, and safety control over virtually every aspect of your marine or reef tank. It constantly monitors critical parameters such as temperature, pH, ORP, salinity (optional), liquid level, and leakage, while offering multiple programmable outputs and inputs to automate heating, lighting, dosing pumps, water‑change systems and other equipment. Paired with the included Energy Bar 832, it can control up to 13 power connections — with individual power‑draw monitoring — and triggers alarms or notifications when required. Because it integrates sensors, probes and automation into a single platform, Apex A3 Pro helps prevent water‑quality issues, equipment failures or tank disasters before they happen.
