EHEIM Ice preventer

The surface of your garden pond should never freeze completely, as toxic gases will be trapped under the ice. The EHEIM ice preventer prevents the pond surface from freezing (up to -20°C), allowing the toxic gases to escape and the vital gas exchange to take place at the pond surface. This means that the biological self-cleaning and detoxification of the pond water remains unchanged and fish and microorganisms are still supplied with oxygen.
