If you need to clean the device or disassemble the glass beaker, follow the steps below:
●Gently remove the pH probe (A) from the plastic holder,
●Pull out the connector of the pump that pours water from the aquarium, which is located in
the beaker on the right side, from the plastic holder. Pay attention to the installed tube to not
damage it (B),
KH Keeper Manual / 436

●Pull the connector of the emptying pump out of the plastic holder gently after the test, which
is provided in the beaker to its left. Pay attention to the installed tube to not damage it (C),
●Gently pull out the glass beaker (D), pay attention to the magnetic stirrer (E) which is inside
the glass beaker so do not lose it.
●Please remember to leave the piece of plastic under the glass beaker. The purpose of this
is to ensure the beaker does not move and positions the plastic tubes to the bottom of the
beaker.
When assembling the kit, proceed in the reverse order. When attaching the probe, insert it into the
slot in the holder, lower it as far as possible and press it from below with a rubber cap. Try to keep
the probe mounted as close to the vertical position as possible.
WARNING: It is very important to put the beaker right (to the maximum position) against the
back wall of the device. If it is not adjusted properly, there is a risk that the magnetic stirrer

Make sure that you have purchased a dedicated Reef Factory reagent for measurements with the
device. It must be purchased separately because it is not included with the device. If you do not
have a dedicated reagent, the measurement will not be possible (result will be incorrect). The
reagent we offer is condensed and it is necessary to dilute it in RO water in a proportion of 1 to 9.
This means that the preparation of 1 liter of the ready solution for measurements requires mixing
100 ml of the condensed reagent and 900 ml of RO water. Below is a table with calculations on
how to properly prepare a reagent of a specific capacity.
WARNING: Remember to stir the reagent in the container every few days so that its
concentration is even throughout the volume of the container.

1. In the lower right corner of the screen you will find the device calibration function .
Performing a calibration is very important as it affects the precision of the measurement.
Remember to perform the calibration process immediately after installing a new device and
always after changing its installation location and changing the installation connection to it
(length of hoses, additional filters or valves, etc.). The calibration process should be
repeated periodically, in accordance with the device prompting "next calibration". Calibration
takes three steps as it is necessary to calibrate the pH probe and the two pumps.
2. The pH probe calibration - for this purpose, uses the pH4 and pH7 testers
included in the kit. You may use liquid or powder solutions by other manufacturers. Sachet
testers are used to prepare ready-made buffer solutions. The contents of the sachet should
be poured into 250 ml of Reverse osmosis water (with a temperature close to 25 ° C),
please do not begin the calibration process until the contents of the sachets have been
