Poor water quality causes it to lie prone to the jar: Many novices change water too fast and change cleaning filter materials in large quantities, which makes koi unable to quickly adapt to the new water quality and lie prone to the jar. This can also be said to be caused by stress reaction. In this case, filtration and sterilization can be carried out, the filter can be fully opened, and nitrifying bacteria can be cultured well. In this way, the water quality will become clear and koi fish will become active.
