Why it matters
Winter aeration without the freeze-up
In cold climates, a stalled airline can shut a system down exactly when your pond needs oxygen most. Here is how running without freeze control compares to running with it.
Without freeze control
Airline left to freeze
- Airlines can freeze up as temperatures drop
- A frozen line stops the system in winter
- Oxygen falls off when the pond needs it most
- The open water hole can close over
With this system
Air keeps moving all winter
- Bleeds off a small, steady amount of air to keep the line moving
- Helps prevent airline freeze-up in cold climates
- Helps hold an open water hole through the coldest months
- Keeps oxygen flowing to protect fish through winter
