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 the ability to control external Calcium
Reactors by controlling CO₂ 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 (Water
Sample) and #2 (Reagent Solution) 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 with Wi-Fi antenna,
• kHLab module with control connection cable,
• 12V/2A Power supply (USA/EU/AUS/JAP),
• High-Quality Lab Grade pH Probe,

Kore 7th Manual / kHLab Edition
3. pH Probe Setup, Maintenance and Preparation
Use only dedicated Pacific Sun pH probes for these calibrations. If you use probes from
another manufacturer, Pacific Sun cannot guarantee the accuracy that measured results
will match actual conditions. The typical lifespan for a pH probe in kHLab is about 16-18
months, but this time can be shortened in the case of long-term exposure to seawater. The
safe replacement time guaranteeing high accuracy is 12 months.
In order to obtain accurate measurements and best performance, the pH probe needs
to be calibrated at two points - pH 4.0 and pH 7.0. Remember to use only dedicated
calibration fluids at aquarium water temperature before performing pH probe calibration.
Closed bottles with calibration fluid for both pH 4 and pH 7 can be placed in aquarium
water to acclimate them to the system temperature.
Warning!
Do NOT let the tip of the pH probe dry out as damage to the probe will
result. The clear cap (small container) protects the pH probe from drying
out.
Warning!
The pH probe must always be calibrated before use. Remove the clear
cap (small container) from the pH probe before starting the calibration
process and before the use of the pH probe.

Page 13
Kore 7th Manual / kHLab Edition
Preparation steps for the calibration process:
1) Remove the storage clear cap (small
container) from the pH probe.
2) It's strongly recommended that before
first calibration the pH probe should be
immersed in tap water to a minimum 4cm
(1.5”) depth (maximum 9cm (3.5”)) and
soak for 24 hours. During this period of
time, occasionally, gently move and rotate
the pH probe several times in the water.
This process will stabilize the pH probe
parameters.
3) After removing the pH probe from tap
water, gently shake the excess water and
wipe using a fresh paper towel. Never
wipe the end probe tip. Just dry by
gently touching/dabbing the end tip with
a paper towel.
Important!
Never expose pH probe to the air for more than 3-4 minutes. The pH probe
should be always in the water or in it's transport protection container.
3.1. Initial pH Probe Preparation - First Use After Purchase
BEFORE calibration
soak for 24h
in Tap Water
Important!
Due to its physicochemical properties, the pH probe will take some time
to stabilize and provide accurate/repeatable results. Consequently, it is
recommended that during the first days/weeks of using the pH probe, the
calibration procedure be carried out more frequently than recommended.

Kore 7th Manual / kHLab Edition
4. Reagent Solution Preparation
This device preparation step is very important. If the reagent dilution ratio is not correct,
the tested results may differ from the actual alkalinity levels. To obtain accurate results, we
strongly suggest using the digital scale for reagent dilution.
Important!
The 1000ml of SUPER Concentrated Reagent included in the package
has to be diluted with RO/DI water (TDS=0) before use in 149 ratio.
EXAMPLE: 100ml of concentrated reagent has to be added to 4900ml of
RO/DI water (TDS=0).
Before beginning the reagent solution preparation steps, prepare two containers:
‒Measuring Container - must have a minimum of 100ml capacity for measuring
the correct amount of concentrated reagent and RO/DI water (TDS=0);
‒Target Reagent Solution Container - must have a minimum of 500ml capacity
for mixing concentrated reagent with RO/DI water (TDS=0).
To prepare ready to use 500ml of reagent solution follow these steps:
1) Prepare an empty Measuring Container.
2) Place the Measuring Container on the digital scale.
3) Turn ON the digital scale.
4) Wait a few seconds and then zero-out the digital scale by clicking (T) Tare button.
Before starting reagent measurement, the digital scale must show 0.00 g on the
LCD display.
5) Make sure that the digital scale is showing [g] as the weight unit. If not then start
clicking (M) button until you see [g] gram unit on the display.
6) Measure exactly 10g of reagent (from a 1000ml bottle with SUPER concentrated
reagent included in the package).
7) Pour out the measured amount into the Target Reagent Solution Container.
8) Place the empty Measuring Container back on the digital scale.
9) Wait a few seconds and then zero-out the digital scale by clicking (T) Tare button.
10) Pour in exactly 490g of RO/DI water into the Measuring Container, then add that
measured RO/DI water into the Target Reagent Solution Container.
11) After adding the whole (10ml of SUPER concentrated reagent and 490ml of RO/DI
water) mix everything by shaking the Target Reagent Solution Container several
times.
The prepared reagent solution is ready for use. We recommend preparing no more than
5000ml of ready to use Reagent Solution. This amount of solution can last for up to 37
days of performed Alkalinity tests (12 tests/day).
