Oase AquaOxy Aeration Ring 60cm
Oase AquaOxy Aeration Ring 60cm

Oase AquaOxy Aeration Ring 60cm

The Oase AquaOxy Aeration Ring 60cm ensures maximum oxygen injection into the water. The secret of perfect oxygenation in fish water or swimming ponds? The oxygen must flow in as fine bubbles. Small air bubbles rise more slowly in the pond than large ones and thus cause a more intensive transfer of atmospheric oxygen into the pond water. But what is the best choice for this job? Aerator ring or aerator rod? How to decide for your garden water: Use an AquaOxy aerator ring where you want to maximise the oxygen input into the pond. Aerator rings are often used in high-quality koi ponds, for example. They are also used in filter systems that work according to the moving bed principle. Aerator rods, on the other hand, have a more discreet effect. The AquaOxy aerator ring (620 mm × 620 mm × 60 mm) is suitable for connection to an OASE AquaOxy 5000 or an OASE AquaOxy 7500. Read more

Features:

  • FINEST BUBBLES: The AquaOxy ventilation hose ensures maximum oxygen injection into the water
  • FOLLOWING THE JAPANESE EXAMPLE: Ventilation rings in particular are preferred in high-quality koi systems, even more so than ventilation rods
