1. Introduction
Congratulations on your Purchase!
The Pacific Sun Kore 7th dosing station and kHLab module are made with the highest
quality materials, and are built to last, helping you to take your reef to the next level!
The Pacific Sun Research and Development team is continuously testing, developing
and releasing new products with new features.
This document serves to cover the basics of the Kore 7th dosing station and the kHLab
module. Details will be made available about additional new products and features as they
are released.
For questions, please contact us at [e-mail] .
1.1. Product Information and Features
Why the Kore 7th/kHLab was developed?
The kHLab module automatically measures seawater alkalinity in the reef aquarium and
maintains the KH set value by automatically controlled Kore 7th doser pumps performance.
What distinguishes Kore 7th dosing station and kHLab from the competition’s products
is that it regulates the dosing of Alkalinity Additive solution (Sodium Bicarbonate or
Carbonate) as well as Calcium (Ca) and Magnesium (Mg) fluids and Mineral Salt.
Another important feature of kHLab/Kore 7th is ability to control external calcium
reactors by controlling CO dosing into the reactor chamber.
The Kore 7th/kHLab device and device performance should be monitored and serviced
on a regular basis. This includes service activities such as regular pH probe calibration (in
4.0pH and 7.0pH solutions) and checking the dosing efficiency of channels #1 and #2 as
these can have a big impact on accuracy and proper device operation.
An incorrect and/or unstable alkalinity level or sudden and/or accidental alkalinity level
changes in the aquarium water can significantly affect the condition/life of demanding
corals such as SPS which are becoming increasing popular in home aquariums. A correctly
configured and programmed device will quickly became a necessary tool for the aquarist in
maintaining alkalinity at a proper and stable level.
1.2. The Kore 7th / kHLab Edition Package
The Kore 7th / kHLab includes:
• Kore 7th dosing station
• 12V/2A Power supply (USA/EU/AUS)
• High Quality Lab Grade pH Probe
• Wi-Fi antenna for Kore 7th dosing station
• Connection tubings for kHLab
• 4.0pH and 7.0pH Calibration Fluids
• 2x500ml Concentrated Reagent for Alkalinity tests. (1 liter allows to prepare 5 liters
ready for use reagent solution and 1 liter allows for about 100 tests).
• kHLab module with control connection cable
• Precise Digital Scale with calibration holder/stand for very precise fluids calibration
• Dedicated calibration/measuring cylinder
• Syringes and precise dosing applicator tips
• Magnetic stirring bar/pellet (inside kHLab module cylindrical chamber)

Kore 7th Manual / kHLab Edition
1.3. The Kore 7th / kHLab Device Features
The kHLab has an ability to measure alkalinity with lab grade accuracy. It can provide
KH measurement values with 0.1 dKH accuracy. It’s a minimal confirmed resolution during
continuous device function. In the case of performing tests manually (in a small time
intervals) resolution can be greater.
1.4. kHLab Device Technical Specifications
‒ Systematic error ISO: ±0.03ml
‒ Numeric division: 0.05ml
‒ Random error: ≤ 0.05ml
‒ Alkalinity range: 5 to 15dKH
‒ Resolution: 0.1 dKH
‒ Device can work in two modes:
1. Monitoring mode
2. Control mode
‒ kHLab module dimensions: L105 x D95 x H172 mm (L4-1/8 x D3-3/4 x H6-3/4
in) – w/out pH probe
‒ Kore 7th dimensions: L510 x D120 x H50 mm (L20-1/8 x D4-3/4 x H2 in)
Monitoring (passive) and Control (active) modes:
1. Monitoring mode
During this Monitoring mode the device measures Alkalinity level and registers
all the values in memory and displays them on doser LCD screen. It makes no
adjustments to Alkalinity level.
2. Control mode
During Control mode device automatically adjusts and maintain the
amount of dosing fluids in channels 4/5/6/7 (Alk/Ca/Mg/Mineral Salt) to control
Alkalinity level. Channels are simultaneously controlled (at the same time).

2. Kore 7th / kHLab Device installation
2.1. Proper device setup and installation
For optimum performance, the height difference between the kHLab device and the
water level surface from where the device will take the water sample for testing should NOT
exceed about 50-60cm (20-24”) and connection tubing length between kHLab module
and Kore 7th doser should NOT exceed 100cm (59”).
The kHLab device can be mounted directly on a wall with the supplied wall mount, or it
can operate sitting on a flat surface.

USB Port for Firmware upgrade.
DC pump Port for DC pump (ATO refill pump).
Optical sensor Connection port for optical sensor (used for ATO/AWC).
Temp sensor Digital temperature sensor port.
Floating sensors port Not used in newest version of software/firmware and designed
for future applications.
Antenna port External Wi-Fi antenna port. Required for proper work!
Reset button Hardware reset switch (short push generate reset signal to
main CPU).
Power supply port Required 12V 1A/2A power supply with 2.1mm plug.
kHLab Digital I/O port Used for connection kHLab Module or Magnetic Stirrer, DC
AWC pump etc.
pH #1 Connection port for pH probe nr 1 (kHLab module).
pH #2 Connection port for pH probe nr 2 (Calcium Reactor).
Important!
1. Make sure that a water mixing magnetic stirrer bar/pellet is put inside
kHLab module test cylindrical chamber.
2. Make sure to connect silicone tubing properly to individual Kore 7th
dosing pumps:
– Pump nr 1 - supplies watersample (aquarium water) to kHLab
test chamber. Do NOT exceed 100cm (39”) length between the
place of taking test water and the kHLab device.
– Pump nr 2 - supplies reagent solution for testing. Try to place
the reagent solution bottle as close as possible to the doser and
at a similar level.
– Pump nr 3 - removes waste water (tested water) from the
kHLab test chamber. This water can be drained to aquarium (we
suggest near the pump sucking in water to the protein skimmer).
The length of the silicone tubing from the pump outlet should not
exceed 150cm (59”).
3. Make sure to connect the control cable between the kHLab device
and the Kore 7th dosing station.
