What are the types of koi? Is this how your koi changes water?

1. Unplug the power supply of the feeding equipment, fish the koi to a container close to the original water temperature, put it into the air pump to increase oxygen, so as to prevent the koi from anoxia due to too long water change time.

2. Drain the old water in the jar with a straw, take out pebbles and aquatic plants for cleaning and disinfection (dilute saline or potassium permanganate solution can be used).

3. Rinse the koi glass tank around, soak and rinse the koi tank with a small amount of light salt water or potassium permanganate solution, rinse it after disinfection, and fill it with new water.

4. After putting the weeds and pebbles, put the koi into the tank.

Under normal circumstances, the method of changing all water is not adopted to prevent accidents caused by inadaptability of koi fish due to water quality differences. At the same time, mechanical damage is easy to occur during fishing, giving disease an opportunity to attack.

2. General water change: refers to once every 1 ~ 3 days, mainly sucking feces, residual bait and old water in koi tank with straw.

During the operation of changing water in koi pond (tank), it is necessary to master light, slow and steady to avoid damaging koi. The water must not be stirred vigorously to prevent the water pressure from damaging the internal tissues of the koi carp.

In the process of adding new water, the water flow should be slow, so as not to damage the koi body surface due to the impact force caused by excessive flow speed.
