Laguna Power Heat De-Icer 315 watts

Maintains an area thawed and open in the pond allowing the release of toxic gases from fish respiration and decomposing organic matter to escape. At the same time it allows oxygen to re-enter the pond. Safe for plastic and liner ponds, includes a highly visible LED light that indicates when it’s on. Thermostatically-controlled on/off feature that prevents overheating and saves energy costs.

• Maintains a vent hole in the pond for proper gas exchange, saving the lives of your fish

Another nice feature with de-icers: The ones we use are thermostatically controlled, shutting off when the water warms up. That means you never have to worry about your de-icer wasting electricity.
