Pond aerator Oase AquaOxy 250 — 250 l/h, model 34064

Oase AquaOxy 250 is a compact pond aerator designed to deliver continuous aeration with an airflow of approximately 250 l/h. Intended for garden ponds, the unit supports oxygenation and gentle water circulation to help maintain biological balance. The device is suitable for use with external tubing and diffusers and is sized for small to medium ponds where steady low-volume aeration is needed to reduce stratification and support fish and aquatic plants.

Advantages

The aerator provides a steady, low-noise supply of air at 250 l/h to help improve dissolved oxygen levels and promote a healthier pond environment. Its compact design allows discreet installation near ponds or inside pump houses, while compatibility with standard tubing and diffusers makes it flexible for different layouts. Continuous operation assists in reducing thermal layering and supports beneficial bacteria by promoting uniform oxygen distribution.

Suitable for

• Small to medium garden ponds requiring supplemental aeration
• Ponds with fish populations that need consistent oxygen levels
• Pond setups using external tubing and air diffusers
• Situations where reduced water stratification and improved circulation are desired

Key specifications

• Airflow: approximately 250 litres per hour
• Application: continuous aeration for garden ponds
• Compatibility: designed for use with external tubing and diffusers
• Suitable pond size: small to medium (depending on biological load and stocking)
• Installation: near-pond placement or inside sheltered enclosure

How to use

Install the aerator on a level surface close to the pond or in a protected housing to avoid direct exposure to weather. Connect appropriate air tubing from the unit to one or more diffusers placed on the pond bottom or in target areas for improved circulation. Ensure secure hose fittings and, if required, use check valves to prevent backflow of water. Operate continuously for best results, and verify airflow periodically to confirm consistent performance.

Usage recommendations

For effective oxygenation, position diffusers to promote even circulation and avoid placing them directly under dense plant cover. Regularly inspect tubing and connections for wear or blockages, and adjust the number of diffusers according to pond size and stocking density. During winter, monitor ice cover and maintain at least some aeration or open-water area to support gas exchange for aquatic life.
