for Koi? When raising Koi, it is very important to change the water for them. Changing water for them is affected by many factors, such as season and whether there is filtration equipment. If it is summer and there is no filtration equipment in the tank, it is best to change the water every 2-3 days. If filtration equipment is present, the water can be changed every 1-2 weeks. If it's winter, their metabolism will be slower, and they can change their water once every 1-2 weeks. If there is filtration equipment in the fish tank at this time, it is also possible to change the water for them once a month.
for Koi When changing water for Koi, the first thing to determine is what kind of water to use, of which tap water and well water are the two most commonly used. However, tap water should be dechlorinated before use. You can put them in the sun for a few days, and if you're in a hurry, you can add baking soda to the water to remove chlorine.
Then adjust the water quality and adjust the temperature and PH of the new water. Generally, the temperature is adjusted to about 28 ℃ and the PH is adjusted to 7.3-7.5 to ensure that there is little difference between the new water and the old water. If the difference is too large, it will cause a sudden change in the water quality in the fish tank, which will adversely affect them. Then a quarter of the water in the original fish tank is pumped out, and the same amount of adjusted water is slowly poured into the tank.
