Ok with the air driven models, im curious of how the water intially enters and exits the skimmer?
i havent seen one personally, i understand the concept of how it works but cant understand the flow of the water to force water in and out.
Thanx

Did you have a specific one in mind? Just as there is variations in design on say Venturi-operated skimmers, the air driven ones come in different flavors as well.
