5.7 How the CO Flipper works
2
The Flipper is a modern, highly effective CO
the most efficient possible use of the valuable CO
While CO bubbles rise slowly in the Flipper, the CO
2
aquarium water. At the same time, other gases which are naturally
dissolved in the aquarium water penetrate into the CO
"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 and thus accumulate in the CO
2
discharged regularly via the special waste gas vent.
The running-in period for the Flipper is approx. 2 days. Initially, the
individual CO bubbles combine to form larger bubbles. As soon as a
2
biological surface layer of microorganisms has formed, the bubbles
rise up to the collector.
5.8 Using disposable Dennerle CO
(connection thread M10 x 1.25)
Primus and Quantum pressure reducers can also be used in
combination with Dennerle disposable CO
• 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
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 esta-
blished 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.

7 Upgrades for CO

cut-off valve serves to cut off the CO
