How long does Koi oxygen open in a day? How long will it die without oxygen?

The oxygen in the fish tank for raising koi is usually about 4-6 hours a day. If the fish tank space is relatively large and the feeding density is relatively small, it is enough to turn on the oxygen for about four hours a day. If their fish tank space is relatively small and their feeding density is relatively high, they need oxygen supply 24 hours a day to maintain their daily needs. If the oxygen is insufficient, the koi will grow poorly because of lack of oxygen.

1. how long does the oxygen of Koi open in a day? The length of the oxygen opening time

of Koi is directly related to the feeding density.

1. When raising koi, if the fish tank is relatively large, it will contain more water, and the oxygen content will naturally be more sufficient. In this case, if you don't have a lot of fish, you only need to give them oxygen for about four hours a day. If they are raised in small fish tanks, but the density is not very high, they can also be oxygenated for four hours a day to meet their daily needs.

2. If the fish tank is too small to give them enough space to swim, they need 24 hours of oxygen supply to ensure their daily needs. In addition, even if the vat is used for feeding, but the feeding density is relatively high, it also requires 24-hour oxygen supply.

In addition to feeding density, it is also necessary for them to reduce the amount of food they are fed. Because too much food will rot and ferment in the water, which will pollute the water quality and accelerate the oxygen consumption in the water.

2. How long will Koi die

without oxygen? For Koi, tank space and feeding density are important factors affecting their oxygen intake. When the space is relatively small and the density is relatively high, they need to continue to supply oxygen for 24 hours, otherwise they may die overnight. But if the breeding density is small and the water can be changed frequently, they can be fed without oxygen.
