• Remove test container from clasp.
Pull off top part of test container.
• Take an ampoule of special CO
cator and ensure that there is no
indicator in the neck of the ampou-
le! For this purpose, shake the indi-
cator down to the bottom of the
ampoule (in the same manner as a
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 inclu-
ding conical reflector into the top
part. Check that the O-rings are fit-
ted correctly!
• Turn test container carefully (ideally
over a kitchen cloth, in case any
indicator spills out) and insert con-
tainer in clasp.
• Use the suction clip to secure the
CO long-term test in an upright posi-
2
tion at a clearly visible point in the
aquarium where a gentle flow of
water prevails.
• Stick the colour matching scale
to the outside of the front pane.
Please note: As the CO takes some time to diffuse into the indicator,
2
the colouring of the indicator always responds to changes in the CO
tent after a delay of several hours. You should therefore always increa-
se the supply of CO in small steps spread over several days until the
2
ideal CO content is attained.

10. Use as a long-term pH test
The pH value in an aquarium is determined primarily by the carbonate
hardness and the level of CO , some of which forms carbonic acid when
2
it dissolves in the water. 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 nitrate, pH plus / pH minus prepara-
tions etc.), the DENNERLE CO long term test can also be used to moni-
2
tor the pH value in the aquarium.
18
For this purpose, you must:
21
• Measure the carbonate hardness of the
aquarium water (tests available from
specialist retailers).
• Stick an appropriate colour matching
indi-
2 scale to the outside of the front pane.
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 appropriate colour scale.
11. If you're keen to know more: How to calculate the
CO content in the aquarium
2
As certain correlations apply between CO content, carbonate hardness
2
(CH) and pH value, the CO content in the water can be calculated as
2
follows:
• 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 adjusting
the number of bubbles accordingly.
Example: Carbonate hardness 4 °d, recommended pH 6.8 +/- 0.1.

12. How the CO Maxi-Flipper works
2
The CO Maxi-Flipper is a modern, highly effec-
2
tive CO diffusor which ensures the most effi-
2
cient possible use of valuable CO
The CO is released at the opening of the CO
2
hose which is located at the bottom of the
con-
2
Maxi-Flipper. The CO bubbles then rise slowly
2
in the Maxi-Flipper, in the course of which the
CO dissolves in the aquarium water.
2
At the same time, other gases which are natu-
rally dissolved in the aquarium water penetrate
into the CO bubbles. These so-called waste
2
gases explain why the bubbles do not dissolve
completely, despite becoming smaller as they
rise in the aquarium water.
The waste gases are substantially lighter than
the relatively heavy CO
2
in the collector at the top. Here they are
discharged regularly and automatically via the
specially developed waste gas vent.
The running-in period for the CO
Initially, the individual CO
biological surface layer of microorganisms soon forms in the Maxi-
Flipper, however. This ensures that the individual CO
through the Maxi-Flipper up to the collector without combining.

• Close cylinder valve.
• Let off any residual pressure in the pressure reducer by opening the
needle valve. Close needle valve. Caution: Tighten only gently!
• Unscrew pressure reducer from CO

14. Adjusting the operating pressure of the pressure reducer
2
The operating pressure of the Exclusive pressure reducer is factory-set to
approx. 1 bar. In the first weeks of operation in particular, the operating
pressure may alter slightly as a result of the washers working loose.

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 dust and metal particles may collect on the sealing
surfaces over the course of time, the check valve should be examined
every 2 years at the latest and replaced if necessary.
.
2
Examination procedure:
2
• 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
2
hose. If so: Replace check valve. If not: Reconnect hose to check
valve.
• Reset number of bubbles.
Don't worry: An effectively functioning aquarium will normally have no
problem coping without a CO
Important note: Use only check valves designed for use with CO
and thus accumulate
as the special CO
2
check valves may become brittle through contact with CO
a short space of time, resulting in leaks. This usually goes unnoticed.

• Take CO Maxi-Flipper out of the aquari-
2
um.
23
• Extract CO collector vertically.
2
• Place CO -Maxi-Flipper into your left
2
hand, so that the suction cups point
towards the right. The open side (which
holds the collector) points upwards.
• Slide front side wall of the Maxi-Flipper
upward by approx. 2 cm.
24
• Remove the side wall.
25
• Remove the CO hose, do not pull it out.
2
• Now clean all components of the CO
Maxi-Flipper with warm water and a soft
sponge. Do not use any detergents.
• Reassemble the Maxi-Flipper in reverse
order. Attention: reinsert the CO hose
2
into the side wall so that the lower end
is at the very bottom of the reactor.
