A pond de-icer should be placed within a pond to ensure your fish’s safety during the winter. Despite popular belief, a de-icer is not used to keep the water warm for the fish. Instead it is used to keep a small hole in the ice so that bad gases can escape. One concern we hear from pond owners is that they are worried about their electricity bill. With rising rates, we completely understand this concern!
At the store, we sell the Aquascape 300-Watt Pond De-Icer. The benefits of this particular de-icer is its low wattage and its ability to turn on and off when necessary. The de-icer goes into off mode once it reaches a temperature of 21°C, reducing its energy consumption. The LED light on top of the de-icer will let you know when it is heating and when it is in off mode.
To further decrease your energy consumption, you can always choose to unplug the de-icer and only run it when you notice ice closing in over top of the pond. The water directly above the aerator will usually be the last to freeze over. Just watch this spot and when the ice is closing in, place your de-icer into the hole and plug it in to keep the ice at bay. Keep in mind, this route will require you to pay close attention to your pond during the winter.
