1. Shake the bottles before use!
2. Rinse out the glass cuvette with tap
water and then several times with
aquarium water.
3. Fill the glass cuvette with exactly
5 ml of aquarium water using the
dosing syringe.
4. Then add 3 drops of reagent A
(indicator) and swirl the cuvette
carefully.
The water sample will turn turquoise.
5. Place the enclosed dropper tip on the
small syringe and draw out
1 ml reagent B (titrator).
6. Now add reagent B from the syringe
to the water sample drop by drop until
the water changes colour from turquoi-
se to dark-blue and violet and finally
to a clear pink colour.
Swirl the cuvette after each new drop.
The measurement is complete when the
sample has reached a clear pink
colour without any blue tinge
(see colour fields on the packaging).
7. The consumption of reagent B
(difference of 1 ml) multiplied by10
constitutes the alkalinity in °dKH.
Example: If the lower side of the
syringe plunger is at 0.28 ml following
titration, then the consumption of
reagent B is 0.72 ml (difference of 1 ml).
0.72 x 10 = 7.2.
The alkalinity of the aquarium water is
7.2 °dKH.
It is possible to carry out the test with a
2.5 ml sample so that the test reagents
last longer or for hard water over
10 °dKH.
If you choose to do this, follow the
procedure described above and
multiply the consumption of reagent B
by 20 following titration.
8. Rinse out the glass cuvette, the syringe
and the dropper tip thoroughly with
tap water after the measurement
process.
How to correct unfavourable
values:
To increase the alkalinity when levels are
too low, we recommend using
Fauna Marin Carbonate MIX or
Fauna Marin Easy dKH.
Also ask our specialists for advice
regarding this.
