I am looking to build a small natural pond (no filters or pumps) in a polytunnel. The last step in designing this is the water aeration method. I've seen various options for solar-powered aeration devices but I'd like to aerate it in a completely natural way if possible. Is this possible? If so how?

    Welcome to Sustainable Living! Can you please add why you want to aerate the water? What do you intend to do with it? Keep fish? – THelper Apr 23 '17 at 11:35
  • Aerate, you mean helping oxygen to dissolve in the water? Or just remove unwanted algae? – J. Chomel Apr 24 '17 at 6:12
  • how deep is the pond? Goal of aeration, how much aeration do you need? – mart Apr 25 '17 at 6:31
  • And while you are busy improving your question, add a link that explains polytunnel and address the question raised under Fred's answer. – Jan Doggen Apr 25 '17 at 7:46

One method that has been used to aerate water in larger water treatment plants is to cascade the water.

Depending on the amount of land available, you might be able to install a stepped cascade, prior to the water entering the main pond - see page 43 in the link.

  • How do you move the water through the cascade? That sound like it require a pump, which the OP did not want. – kingledion Apr 24 '17 at 17:55

    @kingledion: difference in elevation. The OP didn't state whether the ground was flat of not – Fred Apr 25 '17 at 4:00

    I agree with Fred's answer. The best way to naturally provide aeration is to let water fall into the pond. If there are no suitable elevation differences, a raised large rain barrel that slowly flows its contents into the pond could be an option. – THelper Apr 25 '17 at 11:00
