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.
Discover how GHL technology makes aquarium care smarter, safer, and more consistent. Managing a thriving aquarium is a rewarding challenge. From dosing and water changes to maintaining stable conditions and ideal lighting – there’s always something to monitor. But the more you automate, the less stress you have to carry. Both for yourself and for your aquatic life. At GHL, we design tools that work together as a complete system – including our ProfiLux aquarium controller, dosing units, sensors, and high-performance lighting – all connected and customizable to suit your setup. Whether you’re caring for a reef, a planted aquarium, or a professional installation, GHL automation gives you reliability, precision, and peace of mind. Automate Water Changes with Confidence Regular water changes are vital – but they’re also time-consuming and easy to postpone. Using the ProfiLux controller in combination with GHL level sensors, you can automate water changes based on…
How ProfiLux is Used in Large-Scale and Research Applications Advanced Monitoring and Control for Public Aquariums, Aquaculture, and Scientific Research Managing water quality is essential in public aquariums, aquaculture facilities, and scientific research, where stability, precision, and automation are critical. In these applications, even slight fluctuations in water chemistry, oxygen levels, or temperature can have significant consequences. GHL’s ProfiLux Industrial Line (IL) and standard ProfiLux 4, combined with KH Director® and ION Director®, provide comprehensive automation and monitoring of all crucial parameters: pH and KH (carbonate hardness) – Ensures buffer stability and pH consistency. Temperature – Prevents thermal stress and seasonal instability. Salinity and Sodium (Na) – Maintains proper osmotic balance for marine species. ORP (Oxidation-Reduction Potential) – Tracks water quality and organic waste breakdown. Dissolved Oxygen (Oâ‚‚) – Is essential for aquarium inhabitants. Calcium (Ca) and Magnesium (Mg) – Essential for coral growth, shell formation, and metabolic stability. Potassium…
