Do not pull the hose off by force or cut it open with a knife, as
this may cause damage to the hose connectors!
5.6 Clean CO
2
Flipper
• Remove CO
2
collector by pulling straight up.
• Place the Flipper flat in your hand so that the suction clips are
pointing to the right. Slide front side panel of the Flipper up-
wards by approx. 2 cm.
• Fold out side panel.
• Take out CO
2
hose, do not pull out.
• Clean all parts with warm water and a soft sponge. Do not use
any cleaning agents.
• Re-assemble Mini-Flipper via the reverse procedure.
IMPORTANT: Insert CO
2
hose in the side panel so that the end is
located at the bottom stop.
5.7 How the CO
2
Flipper works
The Flipper is a modern, highly effective CO
2
diffusor which ensures
the most efficient possible use of the valuable CO
2
fertilizer.
While CO
2
bubbles rise slowly in the Flipper, the CO
2
dissolves in the
aquarium water. At the same time, other gases which are naturally
dissolved in the aquarium water penetrate into the CO
2
bubbles. These
“waste 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
and thus accumulate in the CO
2
collector at the top. Here they are
discharged regularly via the special waste gas vent .
The running-in period for the Flipper is approx. 2 days. Initially, the
individual CO
2
bubbles combine to form larger bubbles. As soon as a
biological surface layer of microorganisms has formed, the bubbles
rise up to the collector.
5.8 Using disposable Dennerle CO
2
cylinders
(connection thread M10 x 1.25)
Primus and Quantum pressure reducers can also be used in
combination with Dennerle disposable CO
2
cylinders:
• Unscrew the adapter with the aid of the enclosed 6 mm Allen
key.
• Turn setting knob as far as it will go in direction "-" (CO
2
supply
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
contact 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
approx. 60 bar (at 20 °C).
• The pressure reducer can be unscrewed again at any time – the
cylinder valve closes automatically. A brief hissing sound may
also occur when unscrewing the pressure reducer – it is thus ad-
visable to unscrew the pressure reducer swiftly at the beginning.
6 What if ... – Troubleshooting
7 Upgrades for CO2 fertilizer systems
Level 1:CO
2
night cut-off valve: The DENNERLE CO
2
night
cut-off valve serves to cut off the CO
2
supply at night by
means of a time switch, as plants do not consume any CO
2
at night. This saves valuable CO
2
.
Level 2:Fully automatic: The Dennerle pH Controller Evolu-
tion measures the pH value in the aquarium continuously
and controls the supply of CO
2
precisely and fully automa-
tically via the
CO
2
solenoid valve.
Fault Cause Remedy
A faint hissing sound
is to be heard at the
screwed connection
between pressure
reducer and CO
2
cylinder.
No more bubbles at
the CO
2
diffusor.
CO
2
bubbles stuck in
the Flipper.
Gas escaping from
the side of the
collector.
Pressure reducer is
skew or has not been
screwed in tight
enough.
Washer dirty or faulty.
Adapter is loose
Solenoid valve closed
CO
2
cylinder empty
Setting knob closed
Hose connection
leaking
Needle valve blocked
Flipper is still in the
running-in phase.
Obstacles on the channels
(snails, algae).
Flipper not installed in
vertical position.
Waste air vent (slit)
soiled.
Unscrew pressure
reducer and screw
back in place without
canting.
Clean sealing
surfaces, or replace
washer if necessary
Screw in the adapter
firmly
Open solenoid valve
Replace the CO
2
cylinder
Open setting knob
Check hose connection,
replace if necessary
Clean and recalibrate
the needle valve.
Await end of
running-in phase.
Clean.
Fit Flipper in an
upright position.
