Any cost or efficiency difference between using an air pump running hose straight to a diffuser as opposed to using air pump to pipe creating a suction or venturi effect to suck water up and drop it creating a fountaim?? The later I believe is air lift. I have watched many youtube videos and one person using a water pump with a hose in the air running to water pump is even titled air lift so it's confusing.
