GHL KH DIRECTOR
WHITE
Dimensions : 220 x 150 x 75 mm
Maintaining alkalinity is the most important aspect of reef keeping, stability is key. If you are looking to achieve exceptional coral growth conditions, alkalinity testing is a must!
Stay consistent with the new KH Director. Monitor, maintain and control alkalinity with ease.
KH Director® comprehends:
KH Director ® is designed to work in combination with a GHL Doser 2 (2.1) Standalone device or a ProfiLux® 3 or 4 aquarium controller 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 the accurate transfer of the medium to and from the KH Director.
A sample of the aquarium water is first sent to the KH Director®. Subsequently, the KH value is precisely determined by slowly adding additional liquid (reagent) and measuring the pH value.
The sample water is then pumped back in and collected in a separate container for later disposal.
What are the costs for the reagent and pH electrode?
Here at GHL we understand the importance of the ongoing costs involved with automated KH monitoring and control. For the KH Director it was particularly important to consider these costs and develop a highly efficient and cost effective product. A single 1000ml bottle of reagent can last up to 3 months when testing 4 times a day with a KH value of 8. The pH electrode used by the KH Director was specifically designed for KH measurement and has an average life of 1 - 2 years
Use between 1 and 5 dosing pumps to add liquids to the aquarium depending on the control difference, KHD automatically calculates the appropriate quantities. Dosages can be delayed in time if the liquids do not need to be dosed at the same time and divided into several sub-quantities per day. It is also possible for the dosing pumps used to follow a dosing program, the quantities calculated by the KHD are then added to this dosing program.
In this mode, 1 to 5 dosing pumps can be used to add liquids to the aquarium depending on the control difference. In this mode, a dosing program is set for the involved dosing pumps and the quantities of the dosing plan are varied by the KHD. If the KH value is correct, the dosing program remains unchanged, if the KH value is too low, all quantities of the dosing plan are increased by percentage. If the KH value is too high, the quantities are reduced. The quantity variation depends on the control difference and is calculated automatically.
In this mode, a calcium reactor can be controlled by the KH value.
A calcium reactor is usually operated by adding CO2 and controlling the pH value; the actual pH value in the calcium reactor is measured by a pH electrode. If this pH electrode is selected in the KH Director Options, the KHD can switch off the CO2 if necessary (KH target value reached), otherwise the normal CO2 control is activated. This mode is only possible with a ProfiLux aquarium computer.
