2 Set-up and connection

2.1 Connect the pressure reducer
• • Remove protective foil from adhesive tape and fix stand in place
with the tape on a level surface next to the aquarium or in the base
cabinet. The level surface must be dry and free of grease and dust.
• Turn setting knob on the pressure reducer as far as it will go in di-
rection " – " (CO supply shut off).
2
• Check that the washer in the connection socket of the pressure re-
ducer, the sealing surface of the disposable CO
threads are clean and free of any damage.
• Hold the pressure reducer and screw the cartridge in without can-
ting until a slight resistance is noticeable – this is caused by the
pin in the connection socket of the pressure reducer, which opens
the cartridge – quickly continue turning the cartridge until it is fin-
ger-tight (even if it hisses briefly).
• Place cartridge with pressure reducer in the stand. The cartridge
must always be upright during the supply of CO
Safety instructions:
If the connection between the pressure reducer/CO
leaks – noticeable through a slight hissing or by using DENNERLE
leak detector spray – the pressure reducer should be tightened as
much as possible (in the case of the Nano pressure reducer, a 19
mm spanner can be used). If this does not help, then empty dis-
posable cartridge outdoors by allowing CO
cape completely. Following this, unscrew the pressure reducer
slowly. Check all threads and sealing surfaces and fit a new was-
her if necessary (see 5.3).
IMPORTANT: The pressure reducer may only be unscre-
wed from the cartridge again when the cartridge is
empty – otherwise, there is a danger of injury resulting
from the uncontrolled escape of CO
2.2 Fitting the check valve in the CO
• Cut a piece of approx. 10 cm in length from the CO
that the cut is straight.
• Connect the short hose to the entrance of the check valve, and the
long hose to the exit. 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
flow direction, i.e. from the CO
• Connect the short CO hose to the pressure reducer.

Nano: Secure hose with clip (to open, push the ends of the clip
apart at the side).
Space: Secure hose with coupling ring.

2.3 Connect Nano Flipper
• Dismantle Flipper: Remove collector. Slide top part up by approx.
1 cm and open up.
• Rinse all parts with warm tap water (no detergents!).
• Insert CO supply hose in the bottom part. The end of the hose must
2
be straight and must fit flush against the stop.
• Press top part into place.
• Depending on the size of the aquarium, fit collector.
• Select a spot in the aquarium where the water movement is good.
The selected location should not be too exposed to light, in order
to prevent algae formation.
• Fix Flipper in vertical position well down in the aquarium.

• Fit hose guide. 23
2.4 Space: Connect to the power supply
The integrated solenoid valve enables the supply of CO
trolled:
1 With a time switch
This serves to cut off the CO supply at night, as plants do not consume
2
any CO during the night. Tip: Connect the pressure reducer to the
2
time switch which is also used to control your aquarium lighting
2 Or with a pH controller
A pH controller such as the Dennerle pH controller Evolution mea-
sures the pH value in the aquarium continuously and controls the sup-
ply of CO precisely and fully automatically via the Space pressure

reducer. 25
Control states:
Power ON = LED ON = solenoid valve open.
Power OFF = LED OFF = solenoid valve closed.
Your CO fertilizer system is now ready for use.

3 Setting the amount of CO
3.1 The right amount of CO
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 fish and other
creatures living in the aquarium are not subjected to any unnecessary
stress.
The CO content can be determined by means of the CO
2
(see 4) or by measuring carbonate hardness and pH value (see 4.7).
