How do koi fish raise water? What kind of water are koi fish raised?

Water cultivation can be divided into the following steps:

1. Disinfection of fish tanks and fish ponds: do a good job of disinfection to ensure that the fish tanks and fish ponds themselves are free of toxic and harmful substances.

2. Water injection and oxygen explosion: Many aquarists use tap water directly to breed koi fish, as mentioned above, there will be more or less residual chlorine in the tap water, and these chlorines will be reflected under the condition of oxygen explosion and separated from the water. This is a quick and effective way to eliminate residual chlorine.

3. Add small fish to the tank: At the beginning, you can put in small small fish, the number can be mastered about 2-3, and it is best to eat small fish that can pull the type. And observe the changes in water quality and the state of the fish in the tank, if the state of the fish in the tank does not become very good, you can fish out one and add nitrifying bacteria.

After a few days, if the fish are in good condition, you can moderately increase the number of fish in the tank, and so on, for about half a month.

4. Prepare to enter the main fish: after raising water for about half a month, you can start to prepare the main fish, but it is necessary to pay attention to one point, because the size and number of fish in the tank are different from the main fish after all, it is easy to cause temporary small fluctuations in the nitrification system Unbalanced, at this time, the main fish needs to pay special attention to the changes in water quality and the state of the main fish when entering the tank, and a small amount of nitrifying bacteria can also be added every day to accelerate the reproduction of nitrifying bacteria.

All water changes need to be dried for 2 to 3 days.

Partial water changes require leaving water at the same temperature for more than one day.

The maintenance of water quality is also very important. In the filter tank, bacteria consume a large amount of oxygen (about the same amount as koi) in order to purify the dirt attached to the filter media, and when the oxygen amount is insufficient, nitric acid will be reduced to nitrite acid, and oxygen will be taken away from sulfuric acid to produce toxic gases such as hydrogen sulfide. When the concentration of nitric acid and nitrite increases, no matter how hard you try, you will not be able to increase the amount of dissolved oxygen.

Raise koi fish. Slightly alkaline water should be used. The water used to raise koi fish should meet the following requirements:

1. Water temperature: The water temperature of koi carp living ranges from 2 to 30 degrees, and the optimal living water temperature is 20 to 25 degrees. In the water at this temperature, koi fish swim actively, have a strong appetite, have a strong physique, and are brightly colored. However, the water temperature should not change suddenly, and the temperature difference should not exceed 3 degrees when changing the water;

2. Hardness: Koi fish like to live in a water quality environment with low hardness, and koi can be raised in both soft and hard water, but it should be avoided to suddenly move the koi from soft water into water with greater hardness, so as to avoid allergic reactions to the fish body.

3. pH.

Koi fish are required to live in slightly alkaline water, which is more suitable for the pH value.

For . Koi do not like sudden changes in water quality, so do not suddenly put them from water with a low pH into water with a high pH value, so as not to cause discomfort due to the large difference in pH value. Koi fish have been in weakly acidic water for a long time, which not only has a bad body color, but also is prone to gill rot.

Koi fish have a healthy physique, bright colors, changeable patterns, and majestic swimming style, and have high ornamental and feeding value. Its body length can reach meters. Koi fish are distinguished by different colors, patterns, and scales.

Among them, the butterfly koi was successfully bred in the 80s of the 20th century, and is famous for its long and smooth fins, which are actually crossed by koi and Asian carp, and are not really koi.

Koi fish are raised with tap water, you need to raise water first, it is best to put tap water in a container for three days before raising fish, <>

When raising koi, choose a weak alkaline water with a pH value and keep the water temperature between 20 and 25 degrees.

Generally speaking, koi fish can be raised with ordinary fish water, but we must pay attention to feeding him professional feed, so that it is more conducive to his healthy growth, and you can usually talk to professionals to learn the correct feeding method.

It is better to use purified water for farming, and the survival rate is high.

The water quality of koi fish is the key, and it is generally better to use slightly acidic soft water. The tap water can be left for 24 hours, and then diluted with boiled water or well water (the best well water is beaten) with water 1:5 to use; If the groundwater is taken directly, it needs to settle for one day before it can be used.

The water temperature should be kept at around 20, below 18 for easy disease. Change the water once a week, one third at a time, to ensure that there is sufficient dissolved oxygen in the water and a high hardness, so as to ensure the healthy growth of the fish. In addition, regular splashing of probiotics such as nitrifying bacteria liquid and photosynthetic bacterial liquid can not only regulate the water quality, but also increase the oxygen content in the water, and at the same time play a role in purifying water quality.

In addition, you can also feed some feed appropriately, such as bloodworms, earthworms, etc.

Koi and goldfish have the same requirements for water temperature and water quality, and the suitable temperature range is 2 30, but it cannot resist the sudden change in water temperature, and the temperature difference suddenly exceeds 2 3 Koi will be uncomfortable, and the optimal water temperature is 20 25; It requires sufficient oxygen and is suitable for living in a slightly alkaline and low-hardness water environment.

Koi fish are kept in aquariums or fish ponds because of their body shape due to the environment. Do not put too many decorations in the aquarium to avoid damaging the fish. Aquarium breeding koi generally choose to be raised in the body length of 20cm below, too large often because the space is too small and affect its normal activities, the best conditions are equipped with filters, water lifters, thermostatic heaters and other facilities, the formation of a complete water circulation system, can effectively maintain water quality.

Koi fish are also not suitable for growing aquatic plants like ordinary ornamental fish, because they will eat the grass, they have a habit of digging, and they tend to get all the grass out of the bottom sand.

Koi have relatively large requirements for aquariums, and the general aquariums used include large cabinet aquariums and round tank aquariums, both of which have their own advantages in breeding and ornamentation. Square aquariums allow players to view from the side and appreciate the overall beauty of the fish, while tank aquariums generally enjoy the bright colors of the koi from the top. From the perspective of breeding, square aquariums can generally be equipped with advanced facilities such as automatic filtration systems and water pumps, which are more convenient for players to raise, while tank aquariums generally use regular water changes to maintain water quality.

How should koi fish be raised, and pay attention to preparing to raise koi fish.

Trapped water: To raise water, you need to trap water first, the method of trapping water is very simple, as long as the water is connected, put it in a sunny place, and dry it for a few days. Filtering:

In order to ensure the cleanliness and hygiene of the water body, it is best to filter the trapped water several times. After the water is injected into the fish tank, turn on the filter and filter it continuously for several hours. Culture:

Clean water is only one aspect, but more important is the cultivation of beneficial bacteria. It is also often necessary to grow nitrifying bacteria in water.

1. Trapped water: water needs to be trapped first, and the method of trapping water is very simple, as long as the water is connected, put it in a sunny place and dry it for a few days. Usually it is dried for one day in summer, two days in spring and autumn, and three days in winter.

The reason why the water is trapped is because the water contains chlorine gas, which needs to be removed in this way.

2. Filtration: In order to ensure the cleanliness and hygiene of the water body, it is best to filter the trapped water several times. After the water is injected into the fish tank, open the filter and filter it continuously for several hours to ensure that the impurities in the water are filtered out, so that the water is more suitable for the growth of the fish.

3. Culture: clean water is only one aspect, more important is the cultivation of beneficial bacteria, usually nitrifying bacteria, this bacteria can convert ammonia nitrogen into nitrate, so as to avoid fish being poisoned, is an indispensable part of the ecological cycle. Nitrifying bacteria need to be poured in every week, lights turned off, and oxygen is blasted into the water to encourage their reproduction.

There are many benefits to raising water, first of all, it can increase the water temperature, koi fish are ectotherms, and a higher temperature is more helpful for their growth. Secondly, water cultivation can improve the dissolved oxygen of the water body, which is also helpful for the respiration of koi fish. In addition, the most important thing in trapped water is to cultivate nitrifying bacteria.

Dear, glad to answer for you: Dear According to your description, here is the answer for you. When raising koi fish, you should choose a weak alkaline water with a pH value and keep the water temperature between 20 and 25 degrees.

When changing the water during the same pants stove, it is necessary to keep the water temperature and the water temperature in the tank consistent to avoid a temperature difference greater than 3 degrees. If the pH value of the water quality drops to about the same level, it will make its body color lighter and suffer from gill rot.
