The ProfiLux aquarium controller and Mitras LX8 LED luminaire form a fully integrated system with digital, wireless communication. ProfiLux manages all aquarium functions—including lighting, pumps, and dosing—from one interface, sending synchronized lighting programs and status data to each Mitras LX8. Alerts appear via the luminaire’s Ambient Glow, allowing seamless coordination without separate apps or controls.
Moonlight in the aquarium: why the lunar cycle matters — and how every GHL luminaire reproduces it Reef life follows the moon. Most aquariums ignore it: the night light, if there is one, is the same every night. Here is why the lunar cycle is worth reproducing, and how it works with every GHL luminaire. Why the moon matters underwater Once a year, in their spawning season, many stony corals release their gametes in the same few nights — often a few nights after a full moon. Numerous reef fish, crustaceans and polychaete worms show the same lunar periodicity in their reproduction. Recent research indicates that an important cue may not simply be the full moon itself, but the sequence of light and darkness around it, including the dark hours between sunset and moonrise in the nights that follow. Moonlight also shapes nocturnal life in a less obvious way: visually…
The IMARCS Foundation, led by President Michael Maddox, is dedicated to addressing the decline of coral reefs through active intervention. Their initiatives include testing zooxanthellae from giant clams to improve coral heat tolerance, assessing mangrove restoration for carbon sequestration, and exploring clam farming as a carbon sink. Their research spans global locations, combining marine ecology and molecular genetics.
The GHL Industrial Line provides a modular automation platform for aquariums, aquaculture, and research facilities. It integrates advanced control, high-precision monitoring, reliable dosing, and intelligent power management with full cloud connectivity. The system supports structured professional installations, offering flexibility and scalability through plug-and-play configurations and custom setups, ensuring efficient and precise environmental management.
GHL systems are meticulously designed to prevent network backdoor risks, ensuring robust security for professional environments like research facilities and aquaculture operations. These controllers function independently without relying on external cloud services, offering optional remote access via myGHL. Network interfaces can be disabled for direct USB operation, minimizing potential vulnerabilities. Proprietary protocols further secure communication by limiting active ports and eliminating generic access mechanisms.
A technical comparison of three automated alkalinity measurement methods: direct titration, pH-differential calculation, and colorimetric analysis. Learn the practical differences in accuracy, stability, and automation potential.
GHL Dosers offer fully automated, measurement-based dosage adjustments to maintain stable aquarium conditions. Utilizing data from GHL’s Director devices, these dosers can automatically modify dosages, ensuring optimal stability. The system supports various control modes and precise settings, with connectivity options including WiFi for standalone units, enhancing user convenience and system integration.
The GHL Doser 3 Peristaltic Pump, featuring a planetary gear, is designed for precise dosing and fluid handling. It operates by pressing a flexible tube with rotating rollers, ensuring smooth liquid movement. For optimal performance and longevity, lubrication of moving parts is essential, with a high-performance silicone paste recommended for its balanced viscosity and food-safe properties.
The GHL lighting and control system, featuring the ProfiLux controller and LEDControl4 modules, enables precise simulation of various light spectra and brightness levels for aquaculture research. This technology supports the University of Rostock’s efforts to optimize rearing conditions for African catfish, enhancing fish welfare and aquaculture efficiency. The ION Director and KH Director further monitor critical water parameters.
GHL offers a hybrid aquarium control system that combines cloud convenience with robust local management. Users can access their systems remotely via the myGHL cloud and GHL Connect app, while maintaining full offline functionality through local network and direct USB connections. This ensures continuous operation and control, even if internet or cloud services fail, safeguarding your aquarium setup.
