The Content Of The Article:

They are majestic, but by no means easy to care for: not properly winterized, the joy of the animals can quickly disappear.

Kois

We do not need to explain why koi carp are so popular around the world. Hardly any other fish impresses with so many different colors and drawings as the Nishikigoi (literally "brocade carp"). It is therefore not particularly surprising that more and more garden pond owners say goodbye to the goldfish and prefer to invest in a koi pond. Not least because the animals have something noble about them. In the past, they were even considered by the nobility as status symbols.

However, there is a small problem: Koi carp are beautiful, majestic animals - but they are not very easy to care for. And many forget that and lay down the animals completely rashly. And that in turn often avenges during or after the winter. Because if you do not make your koi pond really winter-proof, you do not need to be surprised if the animals do not make it through the cold season. So here is a lot to consider.

Tips for wintering koi carp

Kois are pretty robust animals. They can tolerate e.g. Temperatures of four to 30 degrees without problems. However, you should know that water has its highest density at a temperature of four degrees and is thus the heaviest at this temperature. Accordingly, even the warmest layer (four degrees) is at the bottom of the koi pond. And this warm layer is now to be preserved. The following tips show how this works.

➤ Tip 1 - Keep a spot free of ice:

A spot in the pond should always keep you ice-free. This is to serve that you can observe your Kois also in the winter and treat also with possible illnesses. Keep a part of the Koi pond free of ice, and make sure that the digester gases escape and that gas can be exchanged.

To keep a spot in the pond free of ice, you should buy a pond heater. Such a device you can buy cheap in three different wattages from the company Schego, for example on koi-gartenteich.aquaristic.net. Otherwise, you can also put on Eisfreihalter from Styrofoam. These work without cables and pumps and still keep an area of ​​the pond effectively ice-free. Styrofoam ice protectors are available, for example on Amazon.de in different sizes and, above all, quite cheap to buy.

➤ Tip 2 - Cover Koi pond:

To prevent the garden pond from cooling down very much, you should cover it as well. For this purpose, e.g. Bubble wrap, Styrofoam or PE pond balls best. The latter variant has the advantage that the balls pass great snow and rain, do not fly away and do not interfere with the gas exchange (further information on gartenteichselbstbau.de).

Of course you can also combine several variants if you do not have the possibility to store many PE-Teichbälle. Then cover, e.g. simply take off one part of your koi pond with Styrofoam and the other part with the PE pond balls.

➤ Tip 3 - Deactivate / remove pond technology:

In winter, adjust the water inlet so that the water from the filter can not flow into the depth region. So it can not mix with the warmer water and disturb the fish by the flow of water even in your hibernation. Also, close the floor runs and take the pumps and fans out of the depth region.

On top of that, you can also switch off the UVC system or even completely remove it from the pond, as there is no longer any algae growth at water temperatures below ten degrees.

➤ Tip 4 - Feeding koi carp properly:

In winter or at low temperatures, the metabolic activities of the koi are reduced in order to save energy. Accordingly, you should or need to feed your animals only a little in winter. It is also important that you use feed that is adapted to the temperature conditions. For this purpose, there are in the trade special winter food to buy, which sinks to the bottom of the pond. So the animals do not have to move much and do not have to come to the cold water surface especially for eating.

Important: do not startle animals!

Never disturb your koi carp in their hibernation. Otherwise, you could trigger a chain reaction. Cause, e.g. loud noises, these can make sure that your Koi startle, move hectically through the pond, they consume a lot of energy and thus do not survive the winter.
