A pond de-icer is not meant to keep the pond ice-free. Instead, they keep an open hole that allows oxygen and CO2 exchange. These are the best pond de-icers available:
The TetraPond de-icer features a 300-watt heating component with an internal thermostat to control the de-icer. It works best with 300-gallons or larger ponds. There’s also a 15-feet power cord for convenience.
Laguna Pond De-Icer
The Laguna de-icer for ponds floats on the pond surface to keep your pond open throughout the winter months. It runs on a 315-watt heating component that works even when temperatures drop to 20-degrees Fahrenheit.
Aquascape 300 Watt Pond De-icer
The Aquascape 300-watt pond de-icer is a simple yet durable ainless steel unit. Inside, there are smart thermo-sensors that constantly measures the water temperature and adjust the thermostat as needed. It comes with a 22-feet electrical cord with a grounded plug.
K&H Pond De-Icer
The K&H pond deicer is designed for outdoor ponds. It’s thermostatically controlled to automatically respond to temperature changes to keep your pond from freezing over. It’s safe for all ponds and will not harm pond liners.
Farm Innovators Floating Pond De-Icer
This floating pond de-icer by Farm Innovators is thermostatically controlled and maintains a vent hole in the ice that allows harmful gasses to escape. It is fish and plant friendly and suitable for ponds of 50 to 600 gallons.
Remember that a de-icer is not a heater because it doesn’t keep your entire pond heated. Only the area around it.
