What kind of water does koi use to raise it will not die? How to maintain the water?

The most important thing in raising brocade carp is water, because the quality of water determines the survival rate of brocade carp, so what kind of water will koi use to raise it? How to maintain the water?

What kind of water do you use to raise brocade carp

1. Tap water: the common water in our daily life is tap water, and many unwitting carp friends will use tap water to store koi directly, which brings some harm to koi. As a matter of fact, tap water is a source of water after disinfection. It contains too much chloride ion and cannot be directly used for fish culture. It needs to be treated and then used for koi culture. Generally, the cooling method is used to put the tap water in the open air ventilated place, with the help of air circulation and sunlight exposure, the residual chlorine in the water can be volatilized and the amount of dissolved oxygen in the water can be increased at the same time.

2. Well water: the well water belongs to groundwater, the water quality is hard and the water temperature is constant. The well water needs to be exposed for more than 12 hours before use to balance the water temperature with the surface water temperature and increase the amount of dissolved oxygen in the water.

3. River water: natural water, the water quality is soft but turbid. Before use, it should be used after purification, precipitation or filtration in the reservoir. The river contains a lot of natural bait, which can make the color of ornamental fish more natural and bright.

II. Water quality maintenance

In the open environment, the feed color of koi has the changes of clear water, green water, old green water, clear water and brown water, but in the aquarium, the water quality is clarified all the year round due to the use of circulating filtration equipment.

1. Clear water: clear water refers to a colorless, tasteless and transparent source of water with sufficient dissolved oxygen and few plankton, which can effectively improve the appetite of fish and promote its growth and development.

2. Green water: green water contains many green algae, such as Chlorella, boat-shaped diatom, grape drum algae and so on, which are auxiliary bait for brocade carp or brocade carp. The water quality of green water is stable, which can promote the bright color of fish, can keep warm and can be used as bait, and is the best water source for the healthy development of fish.

3. Old green water: it is developed from green water, a large number of algae die in the water, and the water color changes from fresh green to light green. Due to a large number of dead algae at the bottom of the cylinder, the water quality is likely to deteriorate day by day. The old green water is mostly used in winter. Due to the low water temperature in winter, the algae grow slowly and the water quality can be maintained for a long time.

4. Clear water: clear water is transformed from clear water or light green water, and its water quality is extremely soft and transparent. The growth and consumption rate of algae in the water has reached a dynamic balance, the water quality is stable and the water color is clear, which is a good source of water for the growth and development of ornamental fish.

5. Brown water: a large number of diatoms propagate in the water, the beneficial algae are reduced, and the stability of water quality decreases, so it should be replaced in time.

Although koi is beautiful, it is important to cultivate it. Otherwise, the temporary beauty will only be a flash in the pan and pay attention to the method of breeding, which will bring joy and enjoyment to the koi in the future and to carp friends at the same time.
