3 Set-up and connection
3.1 Connecting the pressure reducer to a CO
3.1.1 Connection to reusable CO
W21.8 x 1/14")
• Using the Allen key, screw the adapter slowly and without canting
into the connection socket of the pressure reducer, tighten firmly.
• Turn setting knob as far as it will go in direction "-" (CO
shut off).
• Connect pressure reducer to CO
is fitted correctly and that the sealing surfaces are clean Tighten
coupling ring finger-tight with 27mm spanner.
3.1.2 Connection to disposable Dennerle CO
nection thread M10 x 1.25)
• Turn setting knob as far as it will go in direction "-" (CO
shut off).
• Check whether the washer in the connection socket of the pressure
reducer and the sealing surface of the cylinder valve are clean.
• Screw pressure reducer slowly into place without canting, until a
slight resistance becomes noticeable: This indicates that the pin in
the connection socket of the pressure reducer has established con-
tact with the cylinder valve. Then swiftly turn the pressure reducer
by roughly a further half-turn and tighten finger-tight. A brief hiss
may occur at this point.
Quantum: The cylinder pressure manometer will now indicate ap-
prox. 60 bar (at 20 °C)
• The pressure reducer can be unscrewed again at any time – the cy-
linder valve closes automatically. A brief hissing sound may also
occur when unscrewing the pressure reducer – it is thus advisable
to unscrew the pressure reducer swiftly at the beginning.
3.2 Fitting the check valve in the CO
• Using a strong pair of scissors, cut a piece of approx. 10 cm in
length from the CO
hose, ensuring that the cut is straight.

• Unscrew both coupling rings from the CO
• Slide hoses as far as they will go onto the hose connectors and fix
with coupling rings.
Important: The arrow on the check valve must point in the CO
direction, i.e. in the direction of the long hose section
• It is also possible to fit the CO
the hose. However, please note that the shorter the distance is bet-
ween pressure reducer and check valve, the faster and simpler it
will be to set the number of bubbles.

Your CO
pressure reducer is now ready for use

Please observe the instructions for use of the devices concerned.
4 Setting the amount of CO
4.1 The right amount of CO
2
For lush plant growth, Dennerle recommends a CO
rium of approx. 20 to 25 mg/l.
Levels of CO
above 30 mg/l are not necessary for healthy plant
2
growth and should be avoided, so as to ensure that the fish are not
subjected to unnecessary stress.
4.2 Determining the CO
content in the aquarium
2
Certain correlations apply between CO
(KH) and pH value. The CO
content in the water can be calculated
2
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 adjusting
the number of bubbles accordingly.
Example: Carbonate hardness 4 °d, recommended pH 6.8 +/- 0.1.
