The main thing you want to do is keep the airline at a slight down grade so water condensation does not collect in valleys of the tubing and freeze a plug in the airline. Some may think that for northern extreme winter conditions it my be better to have a short airline run to the pond to reduce chance airline freeze up. It is debatable - pros & cons. Other northern pondowners may weigh in on this. For your application use 1/2" or 3/4" ID black irrigation pipe (Lowes, Home Depot, many local hardware stores). The 3/4" is less likely to have frozen water plugs due to larger ID. When you get to the pond then use weighted hose.
