The Tetra Pond De-Icer creates a safe, open patch of water to allow those gases to vent while minimizing energy use thanks to a built-in thermostat. Finished in a natural stone look, this unit blends into outdoor settings and operates effectively in temperatures down to -20°F. UL listed and backed by a 3-year limited warranty, it's designed for long-lasting winter performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the de-icer protect fish during prolonged freezes?\u003c\/h3\u003e\n\n\u003cp\u003eBy maintaining an ice-free opening, the de-icer prevents trapped gases from accumulating and enables gas exchange at the surface.
