GHL&#8217;s proven controller delivers precise measurement and control of pH\/ORP and temperature, 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. Conductivity measurement is easily added at any time via an expansion card \u2013 no hardware replacement, no disruption to your setup.<\/p>\n<p>The ProfiLux 4.1e connects via WiFi, LAN (Ethernet), and USB \u2013 for maximum flexibility in choosing the most reliable connection. The wired LAN port delivers the stable network connectivity that demanding installations require. OTA firmware updates are applied wirelessly or via network \u2013 no USB cable needed.<\/p>\n<p>At the heart of the ProfiLux 4.1e runs ProfiLuxOS \u2013 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.<\/p>\n<p>Stay connected via the GHL Connect app, built-in webserver, email notifications, or the myGHL cloud service \u2013 from anywhere, on any device. GHL Connect and GHL Control Center also work fully locally on your home network. No cloud dependency required.<\/p>\n<p>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\u00ae for continuous alkalinity control, or the ION Director\u00ae for calcium and magnesium monitoring \u2013 all seamlessly integrated. The smart way into the GHL ecosystem \u2013 with the connectivity to match.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The smart entry into professional aquarium control \u2013 with wired network connectivity.
