Pond Boss Forums AERATION Systems questions CFM VS PSI

Find out if the pump was rated at depth.

Also look for the rating in MPa(megapascal). If it has that rating, it can be converted to PSI. You pump should have a chart indicating flow at depth as well.

1 MPa =145.038 PSI

So 0.01 would be 1.45038 PSI

I use an aerator was rated at 0.12 MPa and 100 L per min and it can bubble the air stone with good flow at 15+ feet deep.
