[References](/in/en/references/) / [Fish pond or Insulation Ball](/in/en/references/?category=fishballs) 13 October 2020 # Protecting the fish with balls An excellent choice for preparing fish ponds for the cold season is the insulating ball, i.e. the Fish Ball. Thanks to its help, fish can safely survive the winter. The balls form a continuous layer of thermal insulation on the surface of the pond, thus the freezing of the pond will be slower, i.e. the number of days when the pond is covered with ice can be reduced. Moreover, combined with the de-icing methods operating on different principles (pumped water flow, heating cable, flow-through central heating, aeration) in winter, it can be an effective solution throughout even the toughest frost to avoid complete freezing of the pond. As a result, there should be no oxygen deficiency in the pond. We receive numerous pictures from our satisfied customers showing the effectiveness of the garden pond insulation balls, some of which are also presented here on our website. ### Related Product [ Fish pond or Insulation Ball Euro-Matic insulation balls are the perfect solution for covering heated fish ponds in a cold season.
