Q: How large of a hole will an aeration system keep open in the ice? I like to keep open water for ducks.

A: No doubt those ducks will appreciate some open water in the winter, and an aerator is the best way to keep that hole open for them. Many factors will affect the hole’s size and how long it will remain open, but here are three important points to consider:
- Size of the System: Larger aeration systems will move more water, and all that water movement will create a larger hole that will stay open longer. If you want a bigger open area, consider a beefier aeration system.
- Depth of Water: Water depth matters, too. An ice-free open area in deep water is more difficult to maintain than one in shallow water, where there will be more water movement at the surface. If possible, plan your open water in the shallow areas of your pond.
- Weather: Mother Nature has her say, too. When it’s cold and windy, it’ll be more difficult to keep that opening ice-free. In fact, frigid temperatures can restrict the hole down to a couple of feet or less! But when the weather warms up, the hole can open to areas of 10 feet or more.
Ideally an aeration system should be matched to your pond’s size and shape, and run all season. Diffusers can then be moved to shallow water for the ducks during winter. Simply place the diffusers evenly across a small area in the shallow part of your pond so they can work together to keep a larger area open.
