Anjon Pond Ventilator - Floating Pond De-icers

The Anjon floating de-icers maintain an opening in the ice during winter months, ensuring proper gas exchange and helping fish survive the winter. An internal thermostat turns the pond heater on just above freezing and off as water warms for a fully automatic operation. Safe for plastic and liner ponds, the pond de-icer will not harm fish or plants.
