The long winter months can be extremely dangerous for fish living in small fish ponds and water gardens. As ice over takes the pond the decaying matter and fish waste can
become trapped causing toxic gasses to be released.
This tragedy can be avoided by adding a pond heater or de-icer to your pond. The heater keeps an area of the pond ice-free, allowing harmful gasses to escape through the opening. This allows the fish to stay healthy and survive the long
winter months.
Pond heaters are designed to float on top of the pond. They are thermostatically
controlled allowing them to shut off when not needed. Pond heaters are safe to
use with a pond liner or a plastic pond.
