When your pond freezes over, oxygen cannot get in and waste gases cannot get out. This can be deadly to your fish! The Atlantic Water Gardens Pond De-Icer fixes that by keeping a hole open in the ice to allow the free flow of gases. Constructed of high-strength and temperature-resistant PPS polmer, this de-icer is incredibly durable. An internal thermostat turns the heater on just above freezing for automatic, energy-conscious operation.
