5.7 How the CO Flipper works

The Flipper is a modern, highly effective CO

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

The running-in period for the Flipper is approx. 2 days.

As soon as a biological surface layer of microorganisms has formed,
the bubbles rise up to the collector.
5.8 Adapter for reusable CO
With the Dennerle adapter (art. no. 2999), Primus and Quantum
pressure reducers can also be connected to all standard reusable CO
cylinders (connection thread W21.8 x 1/14").

7 Upgrades for CO
Level 1: CO
cut-off valve serves to cut off the CO
means of a time switch, as plants do not consume any CO
at night. This saves valuable CO
Level 2: Fully automatic: The Dennerle pH Controller Evo-
lution measures the pH value in the aquarium continuously
and controls the supply of CO
tically via the CO
