High temperatures lower oxygen levels in ponds because warm water holds less dissolved oxygen than cold water.

On top of this, koi become more active and require more oxygen at higher temperatures. This combination of factors can lead to oxygen depletion, potentially harming or even killing the fish

Pond aeration is the process of adding oxygen to pond water. This is crucial for a healthy pond ecosystem, as it supports aquatic life and helps break down organic matter.

Aeration can be achieved through natural methods like waterfalls or by using mechanical devices such as aerators or fountains.
