Safety rules for carbon dioxide (CO ) cylinders
2
• Use only to supply CO to aquaria.
2
• CO cylinders are highly pressurized. The following instructions should therefore be observed:
2
• Do not throw CO cylinders. Store in cool conditions. Protect from sunlight and temperatures of over 50 °C.
2
• Use only when fitted with suitable pressure reducers for reusable CO
reducer models Profi 2000, Compact, Professional and Exclusive.
• Cylinders must always be in an upright position when supplying CO
• Do not open CO cylinders by force.
2
• Do not empty CO cylinders completely. Refill only at authorised CO
2
Remove cage before refilling.
• CO gas is heavier than air and has a suffocating effect in high concentrations.
2
• Therefore, avoid breathing in CO gas.
2
• Keep out of reach of children.
• Store CO cylinders in well ventilated areas and not in cellars.
2
• Please note the following when transporting individual cylinders in vehicles: Secure to prevent from sliding and rolling around, as the valve may
otherwise incur damage and CO gas may escape. Ensure adequate ventilation by means of an open window, by switching on the blower, etc.

Set-up and connection
1. Connect the Pressure Reducer
• Close the needle valve by turning in
anti-clockwise direction (if it is not yet
closed). IMPORTANT: Tighten only
gently!
• Fit pressure reducer to CO
with coupling ring. Tighten coupling
ring with supplied 30 mm spanner.
Ensure that the washer is fitted
correctly and that the sealing surfaces
are clean!

The right amount of CO
(number of bubbles)
4. The right amount of CO
For magnificent plant growth, DENNERLE recommends a CO
aquarium of between 15 and 30 mg/l, between 20 and 25 mg/l
are ideal.
The number of bubbles per minute required to achieve this level of CO
depends on a variety of factors, such as the types of plants in the aqua-
rium, motion of the water, surface area/volume ratio, etc. That's why
it is always necessary to determine the CO
individually.
5. Determining the CO content in the aquarium
2
Certain correlations apply between CO
cylinder
(CH) and pH value. The CO content in the water can be calculated
2
2
accurately on the basis of the pH value and carbonate hardness.
Suitable pH and CH 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.

Pressure Reducer 6. Setting the number of bubbles
2
Rule of thumb for the basic setting: start with approx. 10 bubbles per
minute per 100 l of aquarium water, i.e. for a 200-l aquarium, for
fertiliser system, such as

example, use 2 x 10 = 20 bubbles per minute.

• Open cylinder valve slowly by turning the
handwheel in anti-clockwise direction.
Unscrew valve as far as it will go, then
screw in again by one half-turn. The
cylinder pressure manometer will now
indicate approx. 60 bar (at 20 °C).
• Slowly open the needle valve, initially
only very slightly, until the first bubbles
issue from the opening of the bubble
counter or the CO diffusor.

• Set the desired number of bubbles on
the needle valve:

- Turn in clockwise direction to increase
the number of bubbles
- Turn in anti clockwise direction to re-
duce the number of bubbles.
