Power Heat 500-Watt Floating Pond De-Icer, Stainless Steel

The Laguna 500 watt Power Heat pond heater will keep an area thawed and open in the pond during the cold winter months, 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, the pond de-icer will not harm fish or plants. The heater has dual zone integrated thermostats to help the heat distribution.
