Why it matters
Winter shutdowns vs. a hole that stays open
Cold months are exactly when a pond needs oxygen most, yet that is when a standard aeration setup is most likely to stall. Here is how going without compares to running the correct freeze control part.
Without freeze control
Airlines freeze and aeration stops
- Airline freeze-ups can shut the system down mid-winter
- The open water hole closes over when it is needed most
- Oxygen stops flowing to fish through the coldest months
With the Freeze Control System
Air keeps moving all winter
- Bleeds off a small, steady amount of air to keep the line moving
- Helps prevent the airline freeze-ups that stop a system in winter
- Helps hold an open hole and keep oxygen in the water
Winter aeration, protected
