Where to place air balls?

[Bradders0807]

My pond is around 10000 litres (2200 gallons), I have a bio filter system, waterfall etc

I would like to know where you would recommend placing 4 air balls for oxygenation, in terms of depth.
Should they be on the bottom, on the shelves, or both?

thanks in advance

Hello and welcome to GPF!

Do you mean air stones? I put mine on the bottom during hot months, and suspended just below the surface during winter.

We were all newbies at one point! Plus, looks like you are in the U.K., so often times we call things by different names.

I have an air diffuser and I have mine on the bottom of my pond and I turn mine off in Winter.

I put mine at different heights and even put some in each of my filters .I never put mine on the bottom because I have my home made pipe down there that dumps some water into the bottom
