Automated Alkalinity Monitoring and Control

The upkeep of Alkalinity is the most important aspect of reef keeping, stability is key. If you’re looking to achieve exceptional coral growing conditions, Alkalinity testing is a must!

Keep it steady with the new KH Director. Monitor, maintain, and control Alkalinity with ease.

KH Director® – Features

Lab-grade KH measurement accuracy

Measure your Alkalinity with lab-grade accuracy. With only a 100 ml water sample, KH Director® can provide measurement values with 0.1 ° dKH accuracy.

User-adjustable test sample volume

In practice, an accuracy of  0.1 ° dKH is not always necessary. For that the test sample volume can be reduced. An accuracy of approx. 0.2 ° dKH can still be achieved with a smaller water sample.

Measurements per day adjustable

If the KH value does not fluctuate strongly the number of measurements can be reduced.

Higher accuracy and saftey provided by additional valves

Test your Alkalinity with confidence and consistency. Built-in valves ensure exacly the same measurement conditios and prevent the sample liquid from flowing back into the aquarium, even in the unlikely event of a fault.

Cost-effective and safe reagent fluid

Each test requires only 1 – 3 ml per measurement.

Automated Data-logging

Examine past test results, catch sudden KH swings, and fine-tune your KH dosing with help from automated data logging.

Automated liquid supply

Automatic supply of KH-boosting liquids. Depending on the method one or more additional dosing pumps required.

Kalk reactor control

Alternatively, the KH value can also be influenced by controlling a kalk reactor.

LED Status Display

The on-board GHL LED logo conveniently provides color-coded status indicators. The various colors show you the condition of your system at a glance.

  • White = Configuration mode
  • Blue = Normal operation
  • Green = Amount of liquid in a fluid container is OK
  • Yellow = Warning threshold – fluid container(s) are running low
  • Red = Alarm threshold – fluid container(s) are empty

myGHL cloud accessible

Access the KHD through the myGHL® cloud service – via GHL Doser 2 / 2.1 or ProfiLux 3 / 3.1 / 4.

Seamless integration w/ GHL system

Through the use of the PAB (ProfiLux Aquatic Bus) connection, KH Director® seamlessly integrates into the modular GHL aquarium system. The PAB connection ensures interference free communication with other GHL PAB-devices such as the GHL Doser 2.1 or the ProfiLux® 4.

Low maintenance design

The KH Director®’s unique design makes it easy to access and maintain the included pH electrode. Calibration and replacement, made easy.

KH value display

View your KH reading whenever, where ever you want via the ProfiLux display, ProfiLux Touch or web browser (myGHL®), additional external display unit optional.

Robust design built in laboratory quality

Every product we build is made to last the test of time. The KH Director® is no exception. Down to the finest of details, the KH Director® is build of durable material and is corresponding laboratory requirements.

Technical Specifications

KH Director® is available in two color options: Black or white

Dimensions (mm): 220 x 150 x 70 mm (w/out pH electrode)

Dimensions (in): 8.66″ x 5.9″ x 2.75″ (w/out pH electrode)

Scope of Delivery

KH Director® includes the following:

  • Device with integrated measuring cell
  • pH electrode, especially designed for the KHD, incl. calibration liquids
  • Testing reagent 500ml
  • Silicone hose
  • Power-supply splitter-cable
  • PAB cable (50 cm / 19.6″)

How does the KH Director® work?

The KH Director® is designed to work in conjunction with a GHL Doser 2 (2.1) Standalone or a ProfiLux® Aquarium Controller 3 or 4 with a Doser 2 Slave for operation.

The 2 inlets and 1 outlet of the KH Director connect to 3 dosing pumps on the Doser 2 (2.1). These 3 pumps are then responsible for accurately transferring fluid to and from the KH Director.

A sample of the aquarium water is first sent to the KH Director®. Subsequently, the KH value is determined precisely with slow addition of a further liquid (reagent) and measurement of the pH value.

The sample water is then pumped out again and collected in a separate container for later disposal.

 

What are the costs for reagent and pH electrode?

Here at GHL we understand the importance of on-going costs involved with automated KH monitoring and control. For the KH Director it was especially important to consider these costs and develop a highly-efficient, cost-effective product. A single 1000ml bottle of reagent can last for up to 3 months when testing is performed 4x per day at a KH value of 8. The pH electrode used by the KH Director was specially designed for KH measurement and has an average lifespan of 1 – 2 years.

Controlling the KH value

KH Director® offers the most comprehensive methods and most adjustment options for the control of the KH value, KH Director® is thus suitable for different systems, eg. Balling® (Light), Triton® or kalk reactor. Depending on the difference between the target value and the current value of KH (= control difference), appropriate activities for increasing the KH value are started.

Choose the optimal mode for your aquarium and customize it individually:

Add-on control mode

Use between 1 and 5 dosing pumps to add liquids to the aquarium depending on the control difference, KHD automatically calculates the appropriate quantities. The dosages can be time-delayed if the liquids are not to be dosed at the same time and divided into several sub-quantities per day. It is also possible that the dosing pumps used follow a dosing schedule, the quantities calculated by the KHD are then added to this dosing schedule.

Adaptive control mode

In this mode, 1 to 5 dosing pumps can also be used to add liquids to the aquarium depending on the control difference. In this mode, you set a dosing schedule for the dosing pumps involved, and the quantities of the dosing plan are varied by the KHD. If the KH value is correct, the dosing schedule remains unchanged, if the KH value is too low, all quantities of the dosing plan are increased as a percentage. If the KH value is too high, the quantities are reduced. The quantity change is dependent on the control difference and is calculated automatically.

Kalk reactor control mode

In this mode, a kalk reactor can be down-regulated depending on the KH value.
A kalk reactor is usually operated by CO2 addition and control of the pH value; the actual pH value in the kalk reactor is measured by a pH electrode. If you select this pH electrode in the KH Director Options, the KHD can switch off CO2 if necessary (KH target value reached), otherwise the normal CO2 control is activated. This mode is only possible with a ProfiLux aquarium computer.

Configuration options

The KH Director® can be operated in two ways:

1.The KH Director® is connected to the GHL Doser 2 (2.1) Standalone via the ProfiLux Aquatic Bus (PAB).

 
GHL Doser 2.1+KH Director
 

With this option, the GHL Doser has full control over the measurement process and behavior of the KH Director. The GHL Doser will control both its dosing pumps and the valves in the KH Director. This will allow the doser to evaluate the measurement results and calculate the KH value.

 

2. The KH Director® is connected to the ProfiLux 3 (3.1, 4) and a GHL Doser 2 (2.1) Slave via the ProfiLux Aquatic Bus (PAB).

 
 
 
ProfiLux+GHL 2.1 Slave Doser+KH Director

KH Director Sets

Operation of the KH Director requires always a GHL Doser with at least 3 pumps, depending on the configuration either as Slave or as Standalone version.
GHL offers these sets:

  • KH Director + GHL Doser 2.1 Standalone 4-way
  • KH Director + GHL Doser 2.1 Slave 4-way

Both sets have a significant price advantage compared to buying separately, they are offered in white and black and in these country versions: Schuko, UK, CH, USA/CND, AUS.
The sets include a PAB cable (50 cm / 19.6″).
