6 CO long-term test Correct
2
6.1 Mode of functioning
The CO long-term test enables additional visual monitoring of the CO
2
level directly in the aquarium.
The colouring of the special CO indicator varies according to the CO
2
content: from • blue = not enough CO through • green = ideal CO
2
content to • yellow = too much CO .
2
The level of CO in the aquarium can be read directly from the colour
2
matching scale in milligrams per litre.

6.3 Mode of use

• Remove test container from clasp. Pull
off top part of test container.
• Take an ampoule of special CO
and ensure that there is no indicator in the
neck of the ampoule! For this purpose,
shake the indicator down to the bottom of
the ampoule (in the same manner as a
37 thermometer is shaken before taking
someone's temperature). Open ampoule
by twisting off the sealing tab.
• Drip the entire contents of the ampoule
into the top part of the test container.
• Slot bottom part of housing including
conical reflector into the top part. Check
that the O-rings are fitted correctly!
38
• Turn test container carefully and insert in
clasp.

39 • Use the suction cup to secure the CO
long-term test in an upright position at a
clearly visible point in the aquarium where
2
a gentle flow of water prevails.
• Stick the colour matching scale to the out-
2
side of the front pane.

Please note: As the CO
diffuse into the indicator, the colouring of the
indicator always responds to changes in the
CO content after a delay of several hours.

6.4 Use as a long-term pH test
The DENNERLE CO
used to monitor the pH value in the aquarium
on a long-term basis (provided that there are
no other substances in the water which will
have a substantial influence on the pH level,
e.g. major quantities of humic acids or nitra-
42
te, pH plus / pH minus preparations etc.):
• Measure carbonate hardness of the aquari-
um water.
• Stick an appropriate colour matching scale
to the outside of the front pane.

now be read directly from the colour scale.
Measure the carbonate hardness regularly
and always use an appropriate colour
scale.

• The special CO indicator is harmless and does not contain any che-

mical solvents. Prolonged skin contact and eye contact should nevert-
heless be avoided.
• The indicator may cause stains - avoid contact with clothing, carpets, wood, etc.
• Any indicator which may be dropped into the aquarium water by
mistake is harmless for all fish, plants and any other creatures living
in the aquarium.
37
• The ampoule is filled with the special CO
2
atmosphere. The filling level may vary for technical reasons.

• Protect the special CO indicator from sunlight, heat and frost. Always

the washer is presumably worn out and should be replaced.
• For this purpose, insert a small screwdriver or similar behind the washer
from the side and carefully lever the washer out.
Be careful not to damage the connecting thread, the pressure pin or
the sealing surface! Be sure to verify that no foreign matter (dust, dirt
particles, metal chips, etc.) enters into the opening of the pressure
reducer!
• Blow air through the connection socket in order to clean it.
• Carefully press the new washer into position using a suitable, non-
metallic object. Be careful not to damage the washer and the connec-
tion socket. Check that the washer is fitted correctly in place.
7.1.4 Examining the CO
indicator under a protective
The check valve protects your valuable pressure reducer from corrosion
caused by back-flowing water. It will operate reliably over a very long
period. However, as dirt, paint and metal particles may collect on the sea-
ling surfaces over the course of time, the check valve should be exami-
ned every 2 years at the latest and replaced if necessary.
Examination procedure:
• Close needle valve on CO
• After 24 hours, unscrew the coupling ring on the side of the check
valve facing the pressure reducer.

• Pull off CO hose and check whether any water has entered into the
