GHL

GHL states that it has operated since 1998 and specifies that its current corporate form was established in 2001. The first date marks the start of the technology business, while the second belongs to the legal structure now named GHL Advanced Technology GmbH & Co. KG, based in Kaiserslautern. The official website identifies Matthias Groß as GHL's founder.

The company develops aquarium computers, probes and measurement modules, control of temperature and water chemistry, dosing, power management and LED lighting. Its ProfiLux system acts as a central platform, linking sensors and actuators to automate marine, freshwater and professional installations.

Design and production are presented as German operations, using a modular approach that lets users expand a system over time. The public identity centres on the company, its Kaiserslautern base and technical continuity since 1998. The ability to log data and control devices from one platform places GHL in aquarium automation rather than the sale of isolated accessories.
