EHEIM Thermo 200 heater for ponds

The surface of the garden pond should never completely freeze over as toxic gases then become trapped under the ice. The EHEIM ice preventer prevents the pond surface freezing over (up to -20°C (-4˚F)) enabling the toxic gases to escape and the vital gas exchange to take place at the pond surface. This allows the biological self-cleaning and detoxification of the pond water to remain unchanged and fish and microorganisms are still supplied with oxygen. Unbreakable stainless steel heater - prevents the pond surface freezing over up to -20°C.
