How to Increase Dissolved Oxygen Levels
Fortunately, there are various straightforward ways to either combat the depletion of or introduce more oxygen into a pond and prevent low oxygen levels. First, it’s important to understand how oxygen becomes dissolved in water.
Oxygen particles dissolve into the water simply by coming into contact with it. Therefore, to introduce more oxygen into a pond, there needs to be more water coming into contact with the oxygen in the atmosphere.
The surface of pond water is always in contact with the atmosphere and will, therefore, have the highest oxygen concentration. This explains why fish swim near the surface of a pond in times of oxygen shortage.
However, this also means that the majority of the water deeper within the pond does not have access to oxygen particles.
In order to increase the oxygen levels throughout the volume of pond water, you will need to increase the surface area that comes into contact with oxygen.
