Keep your pond from freezing over with the Pondmaster Floating Winter Pond De-Icer, the most popular de-icer on the market. The unique doughnut-shaped design promotes a healthy environment during winter in any sized backyard pond. De-Icers prevent fish loss during cold weather by allowing toxic gasses from beneath the ice to escape.
The 120-watt unit uses an internal thermostat to reduce heating time and save electricity and a long power cord (18ft) that allows placement anywhere in your pond. Internal electronics are epoxy sealed, with a double-sealed shell for extra watertight protection. It will not harm flexible liners or preformed ponds.
