Is it better to change a little water every day, or a lot of water every week? 40

Look at the density of raising, if there are more fish, change the water once every three days, and the remaining part of the tank can not be changed, if the raising is less, the water is not dirty once a week, and don't change it all, and you can't change it too often!

Fish and flowers must be diligent, it is best to change the water once every two or three days, and the amount of water can be one-third or one-half. If there are more fish, change a little every day, and if there are not many fish, you can change some in four or five days. If you don't want to change the water so frequently, you can change it once a week, and change a lot of it each time.

If there is no oxygenation or filtration equipment, it is necessary to change some frequencies, not to change it every day, one third at a time, and the filtration equipment can be changed for a long time.

Usually, small fish change the water once every 2 or 3 days, and the number of water changes is determined according to the number of small fish, excretion, and residual food. When replacing the new water, the new water needs to be placed in the sun to remove chlorine, and the water temperature difference should not exceed 4 degrees or more. If the water quality becomes turbid again during the feeding process, it is necessary to change the water for a second time in time, but only replace the old water 1 3 to avoid causing discomfort to small fish.

The small fish should be changed every two to three days, and the big fish should be changed in one to two days, because of his. Garbage, in the water will be gastrointestinal scale, and then polluted, this is the frequent water change.

In summer, the water quality is easy to deteriorate, and it is easy to breed aquatic organisms, so it is best to change the water more frequently. In winter, you can extend the water change time, if you find that the goldfish surface to drink water, then this time you need to replace the new water, I suggest that you raise some aquatic plants in the fish tank, photosynthesis can produce oxygen, so that the survival time of the fish can be extended.

If you have a large fish tank, try to change it a little bit a day. The small fish tank can be changed every three to five days.

A smaller fish tank can change the water once every two days, or a day, and a larger fish tank can change the water once every four or three days.

The big fish tank is changed once a week, and the small fish tank is changed every two or three days, and once a day is too diligent.

It's good to change a little water every day, because fish need to change more water.

I think it would be cleaner to change it once a day.

Fish farming cannot change the water every day, and there is a saying that when the water is clear, there are no fish.

Try to change it every two to three days.

Remember to change the water once a day, just change the water from the previous day.

Change it all in a week, that's how it is in my house.

Fish farming is about changing the water once a day.

I suggest you try both first, and choose whichever is better.

It can be once a day. When changing the water, pay attention to the sufficient, slow, dechlorination, water temperature, conditions, pH, electrolysis and other details. Because at this time, the fish no longer have a little wind and rain.

If there is a diseased fish, you can change the water once a day, 1 3-1 2 each time. Each replenishment time is about 6 hours. The effect on sick fish is already minimal.

Tips for raising goldfish.

Choosing good fish is one of the basic skills of goldfish farming. When choosing fish, you should choose those that look round and beautiful. This is a genetically good and healthy fish.

The number of fish raised should match your own tank. The ideal water-to-fish ratio is 1000:1.

The body length of the goldfish should be at least 1:10 with the length of the fish tank.

In this way, the water quality of the fish can be guaranteed to be good, and the amount of dissolved oxygen is sufficient. Raising water is the second basic skill of goldfish farming. A week before bringing the goldfish home, open the tank, raise the water, and put a few small fish in the tank to see if it is suitable for the goldfish to survive, so that the nitrification system can be established.

It depends on what kind of breed it is, some varieties are easy to die, and they will die if they change the water every day, so it is generally good to change it once a few days Pay attention to raising small goldfish to meet the following requirements: 1Change the water once a week and don't change it too often.

2.It is recommended to keep some aquatic plants in the fish tank. 3.

Adjust the water temperature to 15-28 degrees. 4.Sprinkle some salt with each water change to prevent disease.

5.Keep the fish semi-starved so that the fish will be more active. 6.

If it is tap water when changing the water, expose the water to the sun for three days.

Keeping the rhythm of the water change in your own tank is important in the process of fish farming.

Can a fish that is not sick survive for 5 days without changing the water?

Water is the foundation of fish farming, and the quality of water is also one of the important factors related to the growth and health of fish. Therefore, it is necessary to properly change the water during the fish farming process. So, how often do fish farmers change their water?

There is no one exact answer to this question, and it needs to be considered based on factors such as the size of the tank, the type of fish to be raised, the density of fish to be raised, and the condition of the filter. Let's take a closer look.

1.Do you change the water for a long time?

In general, it is necessary to properly close the air and replace the water for a period of time. Theoretically, the water in the fish tank can be kept clear, transparent, and odorless without replacement. However, it is generally recommended to change the water in the fish tank at least once a week, and it is best to change the water no more than 1 3 times a time.

And for large tanks (more than dozens of liters) type of fish tanks, the time to replace the water can be adjusted to 15 days -20 days, if the fish tank has a filtration device, according to its different filtration efficiency, it can also be adjusted accordingly.

2.Fish species.

Different species of fish have different requirements for water quality, and the time to change the water should also be different. For example, marine organisms have very high requirements for water quality and need to be replaced more frequently to maintain water quality; Freshwater fish, on the other hand, have more lenient requirements for the water quality of the tank.

3.Fish density.

Fish density refers to the number of fish per unit of water volume. How can you tell if the density of fish is appropriate? It is generally recommended that there should not be too many fish in the fish tank, and the density of fish should not exceed the standard of 2 3 fish in liters.

In an overcrowded fish tank, the waste from fish metabolism will lead to poor water quality in the fish tank, so proper water replacement is important to maintain water quality and fish health.

4.Filter case.

Filters can improve water quality by removing undesirable substances such as contaminants, debris, germs, nitrides, etc. Therefore, the role of the filter is very important for the water quality of fish farming. If the fish tank is equipped with a high-efficiency filter, its filtration effect will be better, and the fish farmer does not have to change the water frequently, and if the fish tank does not have a filter, it needs to pay more attention to the water quality, and the time to replace the water should be more frequent.

It is important to note that these rules are not fixed, and fish farmers can change the water in a more appropriate way based on their own situation and the observed condition of the fish. If the water in the fish tank is yellow, peculiar smell, turbidity and other abnormal situations, and the body surface of the fish appears white, red, etc., the water should be replaced in time to avoid adverse effects on the health of the fish.

In short, how often to change the water for fish farming is a matter that needs to be comprehensively considered the size of the fish tank, the fish species, the density of fish and the filter. If you are not sure about the time to change the water, you may wish to check the water quality changes of the fish tank regularly, and determine the frequency and amount of water replacement as needed, which can effectively maintain the water quality of the fish fillet growth environment.

How often to change the water is best for fish farming depends on a number of factors such as the tank's filtration system, the number of fish, water quality and water temperature. Generally speaking, if the filtration system is more than the harmful substances produced by the fish every day, and the water quality is always good, then it is theoretically possible to never change the water except for the socks to replenish the evaporated water. However, in order to maintain the water quality and the health of the fish, it is advisable to change the water regularly, and in general, it is appropriate to change one-quarter to one-third of the amount of water once a week.

If there are aquatic plants in the tank, the water is usually changed once a week, and one-third to one-quarter of the water is changed each time. In addition, it is best to choose the time to change the water during the day, and the old water needs to be drained and re-injected with new water to reduce the impact on the fish.

In addition, if you want to keep fish at home, you need to pay attention to factors such as water quality, water temperature, and fish population, and carry out regular inspections and maintenance to ensure the health and well-being of the fish.

How often fish are changed depends on a variety of factors, such as the size of the tank, the number of fish, the type and quantity of feed, the effectiveness of the filtration system, and so on. Generally speaking, it is recommended to change the water at least once a week, and the amount of water should not be less than 1 3 of the total water volume of the fish tank, which can effectively dilute the waste and reduce the concentration of ammonia nitrogen, and keep the water balance imitation clear. If the tank is too small or the number of fish is too large, it is recommended to change the water every 2-3 days.

At the same time, it is also necessary to clean the filter and fish tank regularly to prevent waste accumulation and bacterial growth.

Fish farming requires regular water changes, which can keep the water quality in the tank good and provide a healthy living environment. In general, the most appropriate time to change the water for fish farming depends on many factors, such as the type and quantity of fish, the type and amount of feed, as well as the size of the tank and the filtration system.

In general, it is recommended to change the water in the fish tank by 1 3 to 1 2 less once a week, which can effectively remove waste, residual food and other contaminants. If you have large fish or a large number of fish, you may need to change the water more often. For small fish, changing the water every two to three weeks is sufficient.

Also, when changing the water, remember not to drain all the water, as this will damage the beneficial bacterial community in the water, which will affect the water quality. In general, some water and sediment should be left behind, and then new water should be added and a water treatment agent should be used to neutralize chlorine and other harmful substances.

In conclusion, fish farming requires regular water changes and adjustments based on factors such as the type and number of fish, as well as the size of the tank and the filtration system. Changing the water regularly can keep the water fresh and provide a healthy living environment for your pet fish.

In summer, when the temperature is high, it is recommended to change the water every three to five days.

In spring and autumn, the water is usually changed once a week or so.

In winter, there is no need to change the water frequently, you can cheat left and change right once in half a month.

1. Water change under normal conditions.

Changed once a week. Each time the water is changed by a quarter to a third of the world, the average fish has basically not been sick.

2. Water change during the spring and autumn seasons.

The alternation of seasons, diseases are prone to occur, the fish change the water once every three or four days, and the amount of water to increase the rolling limbs should be increased, which is conducive to keeping the water quality clean and greatly reducing the probability of fish disease.

3. Change the water during the illness.

It is changed every two or three days, and the amount of water exchange should also be increased, so that half of the water can be changed, which is conducive to the rapid recovery of the fish and the adjustment of the whole state.

How often fish are changed depends on a number of factors, including the size of the tank, the number and variety of fish, the way they are raised, and the quality of the filtration system.

Generally speaking, it is recommended to replace about 20% of the water in the average household fish tank every week. If you have large fish or large quantities of fish, you may need to change the water more often.

In addition, you should pay attention to the water quality in the fish tank. If you notice that the water quality is getting worse (for example, the water is cloudy or smelly), you should replace the water promptly. In addition, regular cleaning of fish tanks and filters is also an important measure to maintain water quality.

In conclusion, fish farming requires regular monitoring of water quality and the health of the fish, as well as changing the water as needed. The specific frequency should be determined according to the actual situation of Kaibeiji.

In addition, when you change the water, you should also pay attention to the following points:

Use the right water temperature: The new water should be the same temperature as the water in the tank, otherwise it will cause stress and discomfort to the fish.

Monitor and remove chlorine and other chemicals: Tap water contains chlorine and other chemicals that are harmful to fish. These chemicals should be removed with a water treatment agent before adding new water.

Pay attention to the quality of the water: Replacing the water in the fish tank with a high-quality water source can ensure better water quality and better health for the fish.

Appropriate replacement: Do not change too much water at once, otherwise it may cause physiological disorders or death of the fish.

How often to change the water for fish farming is the most appropriate, which needs to be considered according to the size of the fish tank, the number of fish, the species of fish, the effect of the filtration system and other factors. In general, the following points can be used as a reference:

1.Tank size: The smaller the tank, the faster the water quality changes and the more frequent the need to change the water. Generally speaking, the water should be changed at least once a week in a 30-liter fish tank.

2.Number of fish: The higher the number of fish, the more organic matter and waste there is in the tank, and the more frequent the water needs to be changed. In general, 1-2 liters of water are needed per fish, and if the number of fish exceeds the capacity of the tank, the water needs to be changed more frequently.

3.Fish species: Different species of fish have different requirements for water quality, and some species of fish require cleaner water quality. For example, goldfish need to change their water and chain more often, and they need more filtration systems.

4.The effectiveness of the filtration system: The better the filtration system, the less organic matter and waste there is in the fish tank, and the less water needs to be changed. In general, the filtration system should be cleaned once a week to ensure its proper functioning.

In short, how often it is most appropriate to change the water for fish farming needs to be considered comprehensively according to the specific situation to ensure that the water quality in the fish tank is clean and healthy.
