Koi is a very popular ornamental fish. When breeding them, we need to pay attention to some problems of summer maintenance. First of all, the water temperature, the summer water temperature may be relatively high, will lead to Koi discomfort. Therefore, when the temperature is very high, some measures can be taken to cool down. First of all, if the fish tank or aquarium is covered, then the cover can be removed in the summer, which can play a cooling role. If there is light in the fish tank, in addition to watching, usually can be less open, light will lead to higher water temperature, and the other is the time of light should be shortened.
Furthermore, there is the problem of changing the water. The water can be changed more frequently, and it can also play a role in cooling. You have to change the water every three days or so, but the amount of water changed each time should not be too much, about a quarter of it will do. In addition, there are some small ways to cool down, such as filling an empty plastic bottle with water, freezing it in the refrigerator, and then putting it in the fish tank after freezing, which is a good choice to cool down.
In summer, the water temperature itself may be relatively high, and receiving direct sunlight may lead to further increase in water temperature, which is not conducive to the growth and development of koi. So, in the summer, try not to let the water be directly exposed to the sun. However, if it is a very deep outdoor fish pond, then the direct sunlight will not affect the deep water temperature, then you can accept the direct sunlight.
