In preparation for winter, pumps and sterilizers should be removed, thoroughly cleaned, and stored indoors. External filters and plumbing should be drained, cleaned, and sealed from water entry where possible. Never drain ponds with rubber liners!
PUMP DE-ICER: 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. 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, consuming only 10 watts of power at a cost of less than one dollar per month. The cord length is 15 feet.
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.
