Re: Suggestions for testing

Hello Roy,

exciting would be a characteristic curve for an airlift like we know from water pumps. For example from 0 to 10 cm discharge head.

Best regards,

@Marcje

Have you ever tried the airlift without 90° like here from Norbert?

One the right side you see my T-piece. That would be used instead of a 90° elbow.

@Marcje: If it's a T-piece and closed overhead, do you expect more or less flow?

Re: FloNergia airlifts vs regular airlifts

Hello,

every air lift pumps and aerates, that's just physics. You want to pump 100 feet up? That could be possible, but is not the focus here at pond airlifts. Therefore we do not have any experiece for 100 ft. discharge head.

Best regards,

Re: Good pump and attachment?

The linked air pumps are inefficient.
