Air pumps

[Andymac]

Hi
I am digging out a 75,000Ltr pond, I am looking for a suitable air pump. Could anyone recommend a pump (make, model) also the Ltr’s per hour required?
Thanks
Andrew

@Andymac welcome to the GPF!

Do you mean an aerator?

Hello and welcome!

As @Lisak1 said, or do you mean a pump to push water through a filtration system?

Is this a wildlife pond? Will you have fish?

If you mean and aerator that pumps air into your pond w/bubbles then I like Danner AP type. Check out the correct volume of pond water to match up to the size you need. I have and AP- 40 and it is like a volcano of bubbles for my 2400 gal pond. I could have went way smaller. You might find them cheaper if you hunt around. I bought mine from Doctors Foster and Smith online back in 2012 for $99.
Here below is the company that makes them:

If you are talking pond water pumps then that's a whole other subject.
