I got a air pump and stone this year, rather than running a water pump all
winter. We have around a 1200gal pond 3 ft deep, in Colorado, and are
having a colder year than normal.
So question is being the air pump is putting fresh air into the pond
will it hurt anything if it does ice over? The fish are down deep and in
winter mood and use less air and need no food right?
Will the gas get out or do I need to keep it open?

Ppeople put air stones in their ponds in winter to keep an opening in
the ice. If it doesn't do that than it is not pumping enough air.
