In a tank planted with plants, the problem of water aeration is solved in a natural way. Stems of mud plants have numerous small channels supplying oxygen to the water. In the case of a vacant pond, we have to help nature. By pouring hot water over ice, you can easily melt holes in it. This way it is enough to make one or two turns. If you put polystyrene floats on the water, the holes will not freeze until spring.
Melting ice should be done very carefully, especially in shallower ponds. Hot water can wake fish and other aquatic animals prematurely, which is dangerous for their lives at this time of year.
