Benefits of Having Pond Aerators

The main purpose of using pond aerators is to increase the dissolved oxygen level in your pond. Compressed air is pushed through the tubing by a pond air pump and released with a diffuser to create tiny bubbles at the water column. These bubbles don’t actually dissolve immediately rather it creates surface agitation which promotes gaseous exchange and thus increase the level of dissolved oxygen.

Because of the pond aerators a water circulation also happens in a stagnant pond. Overall these activities have benefits of their own. Lets check the benefits of pond aerators –

  • Surface agitation increased dissolved oxygen level
  • Prevents pond water being stagnant and decrease algae bloom
  • Keeps ice from forming in winter

Increased water flow can help to prevent algae blooms since spores will be carried away from the surface, exposing them less in the sunlight and deprive necessary nutrition.

The water circulation due to aeration keeps the water all mixed together and prevents from becoming stratified. This lets fish to use the entire pond instead of just the top layers.

If you live in an area where freezing temperatures are common in the winter, your entire pond can freeze over, cutting off oxygen to the water and killing your fish. Running pond aerators during the winter prevents the pond from freezing and thus ensure safety of your fish.
