@mickphoenix geyser/airlift same thing I think. how do you differentiate? airlift is just the principal of the air rising and lifting the water too. what you do with it from there is moot
@mickphoenix well, you say you're "stuck" on the geyser design, and as an airlift in it's normal form has the same effect and the name is used interchangebly for this type of pump I was curious as to why you were differentiating. If your purpose is to move larger volumes of water for your given system size; fine bubbles move more. But you may be looking for the showy effect of a large plug of water
