Description
Your aquarium runs 24/7 – and so does the ProfiLux 4. GHL’s aquarium controller delivers precise measurement and control of pH, temperature, redox/ORP, and conductivity, alongside 32-channel illumination simulation (clouds, storms, moon phases, seasonal lighting), 16-channel stream and return pump control, 32-channel dosing pump control, automatic water change management, and level/flow/leakage monitoring.
At the heart of the ProfiLux 4 runs ProfiLuxOS – not a general-purpose platform adapted for aquariums, but an operating system designed from day one with one priority: keeping your aquarium safe. Purpose-built hardware, purpose-built OS. No shortcuts.
Stay connected via the GHL Connect app, built-in webserver, email notifications, or the myGHL cloud service – from anywhere, on any device. GHL Connect and GHL Control Center also work fully locally on your home network. No cloud dependency required.
Three built-in expansion slots accept Expansion Cards for additional measurement inputs. The optional Expansion Box 2 adds five more slots. Pair your ProfiLux with the GHL Doser for automated dosing, the KH Director® for continuous alkalinity control, or the ION Director® for calcium and magnesium monitoring – all seamlessly integrated. Trusted by aquarists across the globe for decades, and still growing.
