•
Secure the CO
long-term test in an upright position at a clearly
2
visible point in the aquarium where a gentle flow of water pre-
vails.
•
Stick the "CO
" colour matching scale to the outside of the front
2
pane.
Please note: As the CO
takes some time to diffuse into the indica-
2
tor, the colouring of the indicator always takes 1-2 hours to respond
to changes in the CO
content. You should therefore always increase
2
the supply of CO
only in small steps of a few bubbles per minute

spread over several days until the ideal CO
4.3 Use as a long-term pH test
Provided that there are no other substances in the water which will
have a substantial influence on the pH level (e.g. humic acids, nitrate,
pH minus preparations), the CO
nitor the pH value in the aquarium.
For this purpose, you must:
•
Measure the carbonate hardness (CH) of the aquarium water
(tests available from specialist retailers).
•
Stick the appropriate "pH" colour matching scale to the outside
of the front pane. ©
21
The pH value of the aquarium water can now be read directly from the
colour scale.
Measure the carbonate hardness regularly and always use an appro-
priate colour scale.
4.4 Replacing the special CO
In order to guarantee the quickest and most exact colour response at
all times, we recommend filling the test container with fresh special CO
indicator every 4 to 6 weeks.
For this purpose, open the test container and pour the old indicator
down the drain. Rinse test container with tap water and dry with kit-
chen paper before refilling.
4.5 Cleaning the CO
long-term test container
2
Use warm water and a soft sponge. Do not use any cleaning agents.
If necessary, grease the two O-rings slightly with Vaseline before re-
assembling the test container. Do not use any other lubricants, as these
may lead to incorrect colour indications.
4.6 Special information
•
The special CO
indicator is harmless and does not contain any
2
chemical solvents. Prolonged skin contact and eye contact should
nevertheless be avoided.
•
Any indicator which may be dropped into the aquarium water by
mistake is harmless for the creatures living in the aquarium.
•
The indicator should be protected from sunlight, heat and frost.
Always keep ampoules protected from light during storage. The
filling level may vary for technical reasons.

4.7 If you're keen to know more: How you can also calcu-
late the CO
content in the aquarium

Certain correlations apply between CO
(KH) and pH value. The CO
accurately on the basis of the pH value and carbonate hardness. Suit-
able pH and KH tests are available from specialist retailers.
•
Measure the carbonate hardness of your aquarium water.
•
Read the pH value which corresponds to the desired CO
from the table. You should set this pH value +/- 0.1 by adju-
sting the number of bubbles accordingly.
Example: Carbonate hardness 4 °d, recommended CO
20 mg/l = recommended pH 6.8

5 Care and maintenance
5.1 Replace the CO
cylinder

•
Empty cylinder: Close cylinder valve. Unscrew coupling ring
using 27 mm spanner and screw pressure reducer onto refilled
reusable CO
cylinder. Open cylinder valve The bubble count
2
setting will be retained.
•
Full cylinder: Close cylinder valve. Turn setting knob of pressure
reducer towards " + " as far as it will go, in order to release any
residual pressure in the pressure reducer (the solenoid valve must
be open for this purpose). Unscrew coupling ring using 27 mm
spanner and screw pressure reducer onto refilled reusable CO
linder. Open cylinder valve Reset number of bubbles.
•
Always close the cylinder valve in order to shut down the CO
supply for a prolonged period. Unscrew the pressure reducer
when the cylinder is to remain out of use for a prolonged period.
5.2 Testing the CO
backflow check valve
2
The check valve protects your valuable pressure reducer from corro-
sion caused by back-flowing water. As dirt particles may collect on the
sealing surfaces over the course of time, the backflow check valve
should be checked at least once a year and replaced every 2-3 years
for safety's sake.
Tip: Install a transparent test hose temporarily between backflow
check valve and pressure reducer/solenoid valve and shut down the
content, carbonate hardness
