Why Winter Aeration Matters
Even when your pond is covered with ice, your fish still need oxygen. Winter aeration isn't optional - it's essential for fish survival.
The Problem with Ice
When ice completely covers your pond, toxic gases from decomposing organic matter get trapped underwater with no way to escape. Meanwhile, oxygen levels drop as fish continue breathing (even in their dormant state).
The Solution
Winter aeration creates a small opening in the ice that allows harmful gases to escape and fresh oxygen to enter. You're not trying to heat the pond or prevent all ice - you're simply maintaining gas exchange.
Equipment Options
De-icers: Float on the surface and keep a small area ice-free
Aerators: Create gentle surface agitation to prevent complete freeze-over
