Oase AquaOxy 7500

The Oase AquaOxy 7500 is a high-capacity, low-noise aeration pump designed to meet the rigorous demands of professionally managed garden ponds, particularly those stocked with koi. Maintaining consistently high oxygen levels is essential for fish welfare and stable water parameters, especially during warmer weather when oxygen levels naturally decline. The AquaOxy 7500 delivers powerful, reliable aeration, supporting healthy stocking densities and enhancing biological filtration by stimulating the oxygen-dependent microflora responsible for breaking down ammonium, ammonia, nitrite and nitrate.

Despite its impressive performance, the unit remains compact and discreet, allowing it to be positioned neatly alongside existing pond equipment. The robust metal housing is rated IP44 for splash protection, ensuring dependable outdoor operation. Advanced low-noise motor technology guarantees smooth, long-term running without intrusive sound – ideal for maintaining a tranquil garden environment.

With a maximum air output of up to 7,500 litres per hour and efficient energy consumption, the AquaOxy 7500 provides a cost-effective solution for oxygenating larger ponds. It is particularly well suited to koi ponds and heavily stocked systems where substantial and continuous aeration is vital.
