If a pond contains fish and winters are cold enough to form ice on the pond surface, a de-icer is required to keep a hole open in the ice to allow toxic gases to escape.
PUMP DE-ICER: Our pump de-icer consists of a small pump suspended 8" above the pond bottom by flexible tubing attached to a foam float at the pond surface. The pump transports the warmer water from the pond bottom to the bottom of the float where it spreads out and leaves an ice-free ring of water around the float. The pump is very efficient and only costs about a dollar per month to operate (specifications: 220 GPH, 10 watts, 15 foot cord). A small fountainhead is included to give the pump a use in warmer weather.

HEATER DE-ICER: When daytime temperatures remain below freezing for weeks at a time, recirculating water from the bottom with a pump de-icer can cause a pond to freeze into a solid block of ice. In such weather conditions, it is essential to use a de-icer that generates its own heat. We offer an energy-efficient heater de-icer that uses only 100 watts, less than one-tenth the power consumption of other heater de-icers. The cord length is 10 feet. Please note that de-icers are not intended to be pond heaters.
