All computers run with an operating system from GHL which has especially been developed for control tasks for the aquarium, terrarium or pond.
Our operating system is robust, flexible, future-proof and offers a maximum operating reliability and an optimal efficiency.
Most of the operating systems have been designed and optimized for special application purposes and can from our point of view not offer the degree of safety and performance which is necessary for the control of your valuable aquarium, pond or terrarium. That is why we trust in our operating system - in which more than 12 years of research and development had been invested.
