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 fixed schedules or on sensor-defined water levels.
Define your minimum and maximum fill levels, and let the system handle the rest. ProfiLux activates pumps, monitors water levels, and ensures consistency – no manual effort required.
This feature scales from small home aquariums to multi-tank systems and is compatible with both freshwater and saltwater setups.
Precision Dosing – No More Guesswork
Accurate dosing is key to maintaining proper water chemistry, especially in reef and planted aquariums. The GHL Doser 2.x and 3 (for precision dosing) and the GHL Doser Maxi (for high-volume applications) deliver reliable results, milliliter by milliliter.
You can create flexible dosing schedules, adapt to measured values, and control everything either directly or as part of a fully integrated ProfiLux system. The result is more stable water parameters and healthier livestock – without the risks of over- or under-dosing.
Monitoring and Safety, 24/7
GHL sensors continuously monitor key water parameters such as temperature, level, pH, redox, and conductivity. For even more in-depth insight, optional modules like the KH Director® and ION Director® extend monitoring to alkalinity, calcium, magnesium, nitrate, potassium, and other vital values.
Unlike many cloud-dependent systems, all data processing and critical inter-device communication in a GHL system happen locally and instantly – directly between devices, without relying on external servers. This ensures maximum reliability and immediate response times, especially in safety-relevant situations.
Cloud connectivity is still available through our myGHL platform, giving you full remote access via the GHL Connect app or web browser – but without compromising the independence and resilience of your aquarium control system.
Smart Lighting, Tuned to Your System
Lighting is more than just brightness – it influences coral growth, plant vitality, coloration, and natural behavior. The GHL Mitras Lightbar and Mitras LX series deliver professional-grade LED lighting with full-spectrum control and high efficiency.
The Mitras LX includes an integrated controller, allowing it to manage all lighting functions independently – including sunrise/sunset, moonlight simulation, weather effects, and acclimation programs. For those who want full ecosystem coordination, the LX can also be linked to a ProfiLux controller, enabling synchronized lighting with other automated tasks such as feeding pauses or water changes.
The result: a highly customizable lighting environment that supports both the health and visual impact of your aquarium – whether you’re running a single light or a fully integrated system.
