Matters needing attention in feeding in koi fish

Note that the smaller the fish tank in koi fish, the more difficult it is to control the water quality, and the greater the water capacity of the fish tank in koi fish, the less difficult it is to control the waste concentration. In addition, many novices buy a small koi fish fish tank, and koi fish fish tank has a filter tank behind it, which is difficult to clean thoroughly. If you want to clean it, you may change too much water. Therefore, novices are not recommended to try this koi fish fish tank.

Keep koi fish for too long without changing the water, and be careful not to change the water too much. The frequency of changing water varies with the species and feeding amount of koi fish, ranging from once a month to once a week, and novices can choose to change it every two weeks. The water exchange rate should be within 1/3, and the water adding speed should not be too fast, at least within 20~30 minutes.
