The GHL Aquarium Controller is a highly advanced and versatile device designed to monitor and control various parameters in your aquarium. It can be programmed to control up to 24 channels, including temperature, pH, and water level.
One of the key features of the GHL Controller is its ability to connect to a smartphone app, allowing you to monitor and adjust your aquarium's settings remotely. This is particularly useful for aquarists who live far from their aquarium or want to keep an eye on their tank while away.
The GHL Controller also includes a built-in dosing system, which can be programmed to automatically dispense nutrients and supplements to your aquarium at set times. This helps to maintain optimal water quality and prevents over-dosing.
The device is also compatible with various sensors, including temperature, pH, and conductivity sensors, which can be used to monitor and control specific parameters in your aquarium.

Setup and Configuration
To set up your GHL aquarium controller, you'll need to connect your devices to the Profilux controller. This can be done using a Profilux Pmini or a Profilux P4.
The Profilux controller is the brain of your system, and it's connected to other devices using a GHL breakout board. If you're using a RapidLed nano dimmable driver, you'll need to connect it to the breakout board as well.
You can program different GHL devices from your PC using the GHL Control Center (GCC). This software allows you to connect to various devices, including the Profilux Light, ProfiLux Mini, and ProfiLux 3, starting with firmware 6.00.

Setup Heater Control
To set up heater control, you'll need a Profilux controller, which can be a Pmini or a P4. I used a Pmini for this setup, but the P4 can also work just as well.
First, you'll need to connect the GHL breakout board to your Profilux controller. This board helps facilitate communication between the controller and the heater.
Next, you'll need a RapidLed nano dimmable driver, which is used to control the heater's power output. This driver allows for precise control over the heater's temperature.
Here are the components you'll need to set up heater control:
- Profilux controller (Pmini or P4)
- GHL breakout board
- RapidLed nano dimmable driver
