In the United Kingdom air pumps are very useful in garden ponds during the summer, especially during the hot and humid weather when the oxygen levels decrease in the water. This is most important at night when the plants stop producing oxygen and consume some of it instead. Koi ponds (which do not normally have plants) use air pumps all year round.

The additional oxygen supply also aids in the bacterial degradation of harmful substances such as ammonia and nitrite, creating a healthy pond environment.

Air pumps can also be used during winter, to keep the surface free of ice instead of using a pond heater. If you do choose to do this, keep the air stone high up in the water, just below the surface as not to disturb the warmer water in the bottom of the pond where the fish will be resting.
