Venturi Air Intake for Aquarium Pump

Venturi air mixing nozzle for a protein skimmer pump in my aquarium. This one is designed to be a snug press-fit around a 32mm diameter x 8mm deep circular pump inlet (such as on the Syncra Sicce PSK1000 Skimmer Pump that I happen to have), and accepts a 10mm (3/8") flexible air hose connection.

That said, unless you have the same or a very similar pump,
