As winter approaches, the temperature gradually drops, and the maintenance of the round fish pond also faces special challenges. Doing a good job in winter maintenance can not only ensure the normal use of the fish pond, but also ensure the health and safety of the fish.

First of all, temperature control is crucial. In cold winter, too low water temperatures can pose a threat to the survival of fish. For fish ponds without natural thermal insulation conditions such as geothermal heat, consider using heating rods to maintain the stability of the water temperature. Generally speaking, the water temperature should be kept within an appropriate range according to the species of fish raised. For example, common goldfish, koi, etc., it is more appropriate to control the water temperature between 4 ° C and 10 ° C. However, it should be noted that the power of the heating rod matches the size of the fish pond, and at the same time, check its operating status regularly to prevent faults from causing sudden drops in the water temperature.

Second, ice management cannot be ignored. When the surface of a fish pond freezes, the ice layer will hinder the exchange of air and water, resulting in a decrease in dissolved oxygen in the water. Therefore, it is necessary to break ice regularly. Special ice-breaking tools can be used to open some small holes on the surface of the fish pond to ensure that air can enter the water and provide enough oxygen for the fish. However, you must be careful when breaking the ice to avoid damaging the fish and the structure of the fish pond.

Moreover, reducing feeding is also the key to winter maintenance. As the water temperature drops, fish 'metabolism slows down and digestion becomes weaker. At this time, the frequency and amount of feeding should be reduced accordingly to avoid too much food remaining in the water, which will lead to deterioration of water quality. Generally, it is fed every 2 - 3 days, and the feeding amount is about one-third of that in summer.

In addition, strengthen water quality monitoring. Although the frequency of water changes can be appropriately reduced in winter, we still need to pay close attention to changes in water quality, such as pH, ammonia nitrogen content, etc. Regularly test water quality parameters and make necessary adjustments based on actual conditions to ensure stable water quality.

Finally, check the equipment and structure of the fish pond. Before winter comes, carefully check whether the filtration system, inlet and outlet water pipes and other equipment in the fish pond are operating normally and whether there is any risk of freezing crack damage. At the same time, check the wall and bottom of the fish pond for cracks or leaks, and repair them in time to prevent further damage caused by low temperatures.

The winter maintenance of the round fish pond requires us to be careful and patient. Through the implementation of these precautions, we can help fish survive the winter safely, keep the round fish pond in good condition next spring, and continue to add vitality to our lives. vitality.
