Refugium/pump question

Actually, since the refugium flow should be on the low side, I'm thinking that air lifts would be vastly preferrable. The only problem with air lifts is that the lift height would only be adequate for a HOB fuge, not a sump.

However, that's when I found THIS: Simple Geyser Pump - YouTube

This is a so-called geyser pump, a really simple no-moving-parts air pressure-powered pump design that is widely used in industrial applications (like waste water treatment plants, etc.)... It's genius, really.

This is the basic schematics:

It has awesome lift height, its only drawback compared to traditional air lifts is that they do not aereate that much.
