Keep the garden pond free of ice

Keep pond and garden pond ice-free On the one hand, the frozen garden pond provides a very special sight in winter. On the other hand, this can be very dangerous for a fish stocking, even deadly. It is therefore advisable to keep the garden pond ice-free at least in places in winter.
thereby the air is completed. Existing plant remains and also leaves lying on the bottom of the pond are also decomposed in winter. The result of this process is that important oxygen is extracted from the water. Due to the frozen ice cover, however, oxygen from the air can no longer be supplied. The decomposition process also produces harmful fumigants that can not escape due to the frozen surface.
The flatter the pond, the more you should make sure that the animals living in the pond feel well during the winter. This is especially true for ponds that have a water depth of less than 80 centimeters. Therefore, some measures should be taken so that the fish population has an optimal habitat even in winter.
First, the garden pond should be winterized before the first frost. This means that branches or leaves, which floats in the pond, should be removed with the help of a landing net or rake. The less old plant parts swim in the water, the less it can decompose in the winter and the less fermentation gases form.
Plants that are below the water surface and are wintergreen promote oxygenation and should be left in the dough.
Then it is recommended to draw water from the pond through this hole, so that the water level lowers. This creates a cavity between the ice and the water, which should be about two to three centimeters high. Then it is advisable to cover the resulting hole with the help of materials that let air through, for example a jute sack. The resulting air cushion between the ice and the water surface forms a kind of insulation, which usually ensures that no further ice sheet is formed.
From the hacking of the ice should be refrained from, as one thereby aufschreckt the fish in the pond. In addition, the hacking causes strong sound waves, which can possibly lead to damage to the swim bladder of the fish.
But also in the hardware store and in the specialized trade one finds products, which ensure that places in the pond remain ice-free. They are referred to as so-called Eisfreihalter. In the most diverse variants and sizes one finds heating systems for the garden pond. The offer ranges from small pond heaters, which are simply placed in the pond, to special solar systems through to complete systems.
Special ice protectors, which are simply placed on the water surface, are made of styrofoam. When the water surface is frozen, they are removed and a corresponding ice-free area is created.
A more comfortable solution is provided by aeration or pond pumps. They ensure that the water keeps moving and does not freeze. The pumps are available in different power levels. Pond heaters heat the water in its entirety and thus prevent it from freezing. For the fish, however, such heaters are not necessary, because at least the native fish feel well in the cold water.
A simple bubble wrap, which is available in the hardware store, can prevent at least a deep freezing of the pond. This is placed on the water surface, the air-filled pimples have to swim down. This bubble wrap acts as an insulating layer and the material is characterized by the fact that any resulting fermentation gases can escape through this.
