Koi fish feeding precautions

Note that the smaller the koi fish tank, the more difficult it is to control the water quality. The larger the water capacity of the koi fish tank, the easier it is to control the waste concentration. In addition, many beginners buy small koi fish tanks with a filter tank behind them. This is difficult to clean thoroughly. If you want to clean it thoroughly, you may have to change too much water. Therefore, this kind of koi fish tank is not recommended for beginners.

When raising koi fish, it is important not to leave the water unchanged for too long. When changing the water, be careful not to change too much water. The frequency of changing the water varies depending on the type of koi fish and the amount of food they feed, ranging from once a month to once a week. Beginners can choose to change the water once every two weeks. It is advisable to change the water volume within 1/3, and the speed of adding water should not be too fast, at least within 20 to 30 minutes.
