Why ProfiLux® ?
Highly accurate measurement and control of all relevant water parameters, with alarm function, data logging*, etc.
Unlike, conventional test kits which are time consuming, ProfiLux can continuously monitor and control parameters such as pH, conductivity, redox, temp, etc.
32-channel* lighting control for most life-like simulation of clouds, storm, moon phases, seasonal lighting, sunrises and sunsets.
The realistic lighting control, together with the dimmable lights from GHL, ensures natural lighting and thus promotes the species-specific behavior of your animals.
Stay connected to your aquariums anytime, anywhere.
Access your GHL device through our universal, platform-independent user interface, GHL Connect. Choose from the GHL Connect app, myGHL cloud service, integrated Webserver, or PC software GHL Control Center for complete control at your fingertips.
Secure communication is essential for reliable aquarium control, and wireless systems can’t match the safety and stability required. ProfiLux Aquatic Bus uses the professional CAN bus system, trusted in critical applications like automotive, to ensure interference-free communication. It provides dependable links between the controller and devices such as Powerbars, Expansion Boxes, and GHL Dosers, supporting cable lengths of up to 100 meters (300 feet).
More safety through GHL´s own and unique for aquarium use specialized operating system, ProfiLuxOS.
Lifetime free support and industry-leading support options.

Award winning
Safe and reliable
Driven by innovation
In 1998, GHL revolutionized aquarium technology with the introduction of the first ProfiLux Computer, featuring advanced functions such as light dimming, pH, and temperature control. Originally developed for private use to enhance safety and convenience in aquarium keeping, it quickly became clear that the exceptional performance and reliability of the prototype could benefit other aquarium enthusiasts as well.
Since its inception, the ProfiLux Controller has been continuously refined. Equipped with a wide range of advanced features, it remains unmatched in versatility. From measuring and controlling salinity and redox to stream pump control, weather simulation programs, an intuitive web interface, free control software and the GHL Connect app, or the cloud-based myGHL service, the ProfiLux 4 sets new standards in aquarium management. Its ever-expanding range of features reflects GHL’s commitment to driving innovation forward.
This dedication has earned the ProfiLux series numerous awards, including being named Product of the Year by German customers in 2010 for the ProfiLux II, followed by additional accolades for the ProfiLux 3 and ProfiLux 4 in subsequent years.
Highlights of this success story include two Innovation Awards from the German federal state of Rhineland-Pfalz – the first in 2005 for the ProfiLux Controller and again in 2013 for the complete ProfiLux System for aquariums, terrariums, and ponds. Most recently, the groundbreaking ION Director received its first award in 2021, marking another milestone in our history of innovation.
GHL remains dedicated to perfecting aquarium technology, ensuring that the ProfiLux Controller continues to be the first choice for hobbyists and professionals today and in the future.
