Oxygen Levels in your pond

There are many factors that will effect the oxygen level in your pond but the main ones are:

Temperature: Warm water has a lower ability to hold onto oxygen than colder water

Animals: The more pond life you have in your pond the higher the amount of oxygen that is required and used up

Water Clarity: Pond plants need light to generate oxygen. The clearer the water the more effective your plants will be

To improve water clarity you may want to consider a pond additive. An air pump will assist in increasing oxygenation in your pond.




When does a Pond need Aeration?

Aeration is a very crucial element in any pond.  Every living thing in the pond requires a constant supply of oxygen and every process that happens in the pond is dependent on oxygen. The fish, plants and even the bacteria need oxygen. 

Aeration is important:

  • At Night:

This is when plants are not converting CO2 into oxygen.  

  • In Winter:

During winter months in colder climates aeration helps to keep a small hole open in the surface of the pond to aid in degassing

  • In Summer:

As water warms up it is unable to hold as much oxygen so dissolved oxygen levels are generally lower in warmer water temperatures. Aeration will also help to circulate your pond and prevent stagnation and so reduce the number of mosquitoes that can breed in your pond.

An Air Pump will supply aeration necessary for your pond all day and all year long.

Oxygen in your pond

Oxygen is essential for your pond. It prevents your pond turning into a stagnant, smelly, swamp where nothing will grow and thrive except algae and mosquitos. The main ways to introduce oxygen to your pond are from the surface, which is why keeping a hole in the ice during the winter is necessary, and also by mixing with water movement. An air pump will provide aeration that supports both surface aeration and air movement.
