The Dennerle CO2 Flipper is a powerful, compact CO2 addition device with an integrated bubble counter function for aquariums up to 300 liters in volume. The Dennerle CO2 Flipper operates very effectively. Despite its compact design, the CO2 bubbles have plenty of time to dissolve due to the long travel distance. It is equipped with a CO2 collection tray and a false gas vent. No motor drive is necessary.

Functionality of the Dennerle CO2 Flipper: The CO2 bubbles exit from the opening at the bottom of the flipper and rise along the ridges. During this process, a portion of the CO2 already dissolves in the aquarium water. The remainder collects in the collection tray and then moves into the water from there. As the CO2 bubbles rise in the flipper, other gases that are naturally dissolved in the aquarium water simultaneously penetrate the bubbles. These so-called false gases are significantly lighter than the relatively heavy CO2 and therefore accumulate in the collection tray at the top. They are regularly expelled through the specially designed false gas vent. The heavy CO2, on the other hand, remains at the bottom of the gas cushion, at the interface with the water. Dimensions: 9 x 25 x 4 cm.
