Hozelock Pond Air Pump 320 & 640

The Hozelock Pond Air Pump is a reliable way to increase oxygen levels and improve water circulation in garden ponds. It is particularly useful during warm weather, when dissolved oxygen levels naturally fall, and in heavily stocked fish ponds.

Available in 320 and 640 LPH models, both pumps are designed for outdoor use and come as complete aeration kits, so there’s no need to purchase the basic airline and air stones separately.

Hozelock Pond Air Pump

Adding extra aeration helps maintain a healthy pond environment for fish and beneficial bacteria. The constant movement created by the air stones also helps reduce stagnant areas within the pond.

During winter, aeration can help maintain water movement at the surface. However, the air stones should be positioned appropriately for the season rather than placed unnecessarily deep in the pond.

Designed for Outdoor Use

Unlike many aquarium air pumps, these Hozelock models are designed specifically for ponds. Their weather-resistant housings allow them to be installed outdoors without requiring a separate pump enclosure.

Additional air stones can also be added where required, allowing aeration to be spread across different areas of the pond.

Why Add Air to Your Pond?

Extra aeration can be particularly useful:

• During hot summer weather
• In heavily stocked ponds
• In koi and goldfish ponds
• When additional circulation is required
• To support filtration and beneficial bacteria
• During periods when oxygen demand is high

Both models are low-wattage pumps designed for continuous pond aeration.
