Q: If I run my aeration all winter, do I need to do anything special?

A: Running your aeration system through the winter is an excellent idea. Aeration helps to break down leaves and debris that make their way into your pond or lake, making cleaning and maintenance easier come spring. The water movement creates a hole in the ice, which allows for gas exchange and keeps water open and available for visiting wildlife. Aeration also circulates the water column, infusing it with oxygen for your fish and plants.
We highly recommend running aeration all year long—except if you plan on doing winter activities on your pond, like figure skating, ice fishing or playing ice hockey. The constant friction created by the water movement weakens the ice that forms, and that could be downright dangerous.
So if you plan to run your aeration system through the winter, here are three winter tasks to add to your to-do list:
- Move your plates into shallower water. Following your aerator manual’s recommendations, move the plates from the deepest areas of your pond to shallower areas. This will give your hibernating fish a warmer place to hunker down when the water temperatures get especially chilly. When the plates are closer to the surface, they will also help to keep a hole open in the ice.
- Check the aerator regularly throughout the winter. After a heavy snow or a storm, head out to the pond and inspect your aeration unit. Remove accumulated snow around it, particularly any that’s blocking the air discharge vent. If you lost power during a storm, check your GFCI; you may have to reset it.
- Be smart and safe. When your aerator is on during the winter, the ice that forms can be thin and uneven, so make sure you keep safety equipment out by your pond. A Life Ring or life vest, rope, blankets and a first aid kit are critical items to have on hand that can save someone’s life.
