If it gets cold enough, water will freeze above the stone. The bubbles are still running under there, but ice closes the opening. The stone is 12" below the surface.I use a Pond Breather too. Why did your air stones freeze ?
The fountain only rises about 8"-10" above the surface, when it's real cold an ice dome forms over it.
