How often should the water be changed in the fish tank and how much each time? Does a fish tank that

The fish tank must be changed regularly, and there is no water-free bathtub The fish tank must be changed, but the water cannot be changed frequently, and even some novices like to change the water thoroughly every time.

A tank of nutritious ecological water was replaced with a tank of stagnant water with a clear soup and tasteless stagnant water, which has neither microorganisms nor oxygen, and this water cannot raise fish. <>

Love fish heart, but good intentions do bad things, usually most of the fish diseases are caused by improper water changes.

Now some businesses are vigorously promoting the ecological tank of fish farming without changing water, which is impossible and unrealistic.

Because if the water is not changed, the water inside is not alive. Since it is not living water, it is almost impossible to raise fish in a very perfect state.

It is that your aquarium filtration system is mature again, but nitrate gradually accumulates in the water body treated by nitrifying bacteria, and excessive nitrate is harmful to aquarium fish.

Therefore, nitrates must be removed, and the only way to remove them is to change the water in batches.

How to change the water in the fish tank There is no fixed standard answer to this question, which is affected by the density of our feeding, the size of the fish tank, the type of ornamental fish and the strength of the filtration equipment.

However, there is still a set of more general practices, which can be used for your reference, of course, everyone's fish species are different and cannot be generalized. <>

To change the water for ornamental fish, it is also necessary to pay attention to the scale, one quarter to one-third of the water change each time, and not too much water at a time, so as not to destroy the dynamic balance of water quality.

The water change is generally five to seven days, and the water change time can be shortened in summer, but the water cannot be changed every day.

If you want to raise the ornamental fish at home, then changing the water is a very necessary and very important job, which must not be ignored.

Even if the native fish ecological tank is relatively rough and raised, it needs to be kept for a certain period of time to change the water, maybe not a week, but at least once a month.

The reason why nature does not need to change the water is that the substances in the water are saturated, and the substances in the water cannot be in an extremely saturated state forever.

If the total amount of material in the water is too large, the aquatic organisms will definitely hang, because the more powerful in the water are the bacteria, and the bacteria also need food.

Don't blame it when the bacteria that cause disease and make the animals hang up grow like crazy, it also needs to break down the animals for their own food.

Water change is to keep the substances in the water in a balance at any time, and it is relatively safe for aquatic life. <>

The fish eat and drink in the water, so the substance in the water is increasing all the time.

Just because the human eye can't see it doesn't mean that these substances don't exist.

There are a lot of plants and sediment in nature, and there is no excessive density, and the fish will find the right density to survive and reproduce on their own.

The reason why nature does not need to change the water is because a large part of the water substances are absorbed and converted by plants, leaving a buffer zone, waiting for the fish to eat, drink and laze before increasing the total amount of water substances, and then the plants to circulate to balance.

Of course, the rainy season can also be seen to some extent as a way to balance the total amount of matter in the water.

Raise water for water. If you don't change the water, the small river outside is fine, but you can't at home. The home can also be called an ecosystem, funny!

The fish tank will have to change the water about once every four or five days, and it is impossible for the fish tank to never change the water, so raising fish is also a very troublesome thing, and you have to be very patient.

Fish tank water change according to the number of fish to decide, generally speaking, seven days to change the water, never change the water of the fish tank is not, the water of the fish tank belongs to the "stagnant water", for a long time not to change the water will affect the life of the fish.

If the water in the fish tank meets the standard, it is enough to change the water once a month under normal circumstances, and one-third or two-thirds of it can be changed at a time. In addition, there is no such thing as a fish tank that never changes the water, except in the small streams and rivers of nature.

There is no specified water change period for fish tanks, when the water in the fish tank is dirty, you can change it, and the kind of fish tank with a good filter can not change the water for a long time.

Generally speaking, the fish tank needs to change the water once a week, and each time the water is changed, it is very suitable to change only 1 5 1 3. If the water is changed too much, the balance of the ecosystem inside the tank will be disrupted, and both fish and plants will not be able to adapt.

For fish tanks with a size of more than 60 cm, because the water quality is relatively stable and the water body does not fluctuate much, it can be changed to 1 3 water bodies each time. For fish tanks with a size of 40-60 cm, because the water quality is not stable enough, the water body fluctuates greatly, so you can change 1 4 water bodies each time, and if the fish tank is smaller, you can change 1 5 water bodies each time.

At each water change, you need to use a straw to suck out the dirt from the bottom of the fish tank. Do not change the tap water directly, it is best to boil the tap water and let it cool before adding it to the fish tank. Tap water contains a lot of bleaching powder and chlorine, which is extremely harmful to fish.

If there is an oxygen concentrator in the fish tank, and there are aquatic plants, then you can change the water for a little longer, and if there is nothing in it, then you must change the water every 3 to 5 days.

The water in the fish tank takes about half a month, and it is more appropriate to change it once, but if it is too long, it may pollute the water and be bad for the fish.

How often should I change the water in a fish tank? Personally, I think the water in the fish tank should be about the same if you change it once a week. If you change too diligently, it is not only troublesome, but also unnecessary.

In order to ensure that the water quality in the fish tank is qualified, the water in the fish tank needs to be changed regularly. The frequency of water changes can be maintained at about every 7 days. If the fish are sensitive to water quality and need better water quality, they can be changed every 3-5 days.

In addition, the frequency of water changes is also related to the season. In the summer, the water quality deteriorates rapidly, so the frequency of water changes should be increased. Fish that change water every 7 days can be changed to 5 days.

In winter, on the other hand, it can be changed every 10 days. <

When raising fish, you need to pay attention to controlling the water quality, and changing the water is an important step. Water changes need to pay attention to the frequency issue. The frequency of water changes is different in different situations.

For example, when there are a large number of fish in the fish tank, in the case of an imperfect filtration system, and in the case of relatively fast impurities, the water should be changed more frequently. However, even so, there is no need to change it every day. Changing the water every day will cause the water quality to change every day, which is not good for the growth and development of the fish, so it is not recommended to change the water every time.

1. Fish's requirements for water quality: The frequency of water change is related to the level of fish's requirements for water quality. If the fish are sensitive to water quality and have high requirements for cleanliness, then the water needs to be changed more frequently and not too long.

Some fish do not have such high requirements for water quality, so the interval between water changes can be appropriately longer. In general, the frequency of water changes will be about once a week, and it can be adjusted according to the specific situation.

2. Different seasons: In different seasons, the specific frequency of water change is also different. In summer, due to the relatively high temperature, the water change is the most frequent at this time, and it cannot be left unchanged for a long time.

In spring and autumn, you can extend this interval appropriately, changing it once a week or so. The frequency of water changes in winter is the lowest, which can be done once every two weeks or so.

How often to change the water in the fish tank is as follows:

Water change under normal conditions:

Every week, I change to jujube. A quarter to a third of the water is changed each time, and the fish are basically not sick.

Water changes during the spring and autumn seasons:

The alternation of seasons, disease-prone, fish change water once every three or four days, and increase the amount of water exchange, which is conducive to keeping the water clean and greatly reducing the probability of fish disease.

Water changes during 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 exchange can be achieved, which is conducive to the rapid recovery of the fish and the adjustment of the state.

Recommendations:

Generally speaking, it is not recommended to change the water in the first month of a newly opened fish tank. Because our main purpose in the first month is to hope that the water quality of the fish tank will stabilize as soon as possible, so we should not change the water too often. Otherwise, it will be difficult to stabilize the water quality of this fish tank, so it will be difficult to stabilize the state of the ornamental fish inside.

Therefore, in the first month of opening the tank, it is best not to change the water. Unless there are some special circumstances, for example, some drugs are accidentally added, resulting in the water quality of the fish tank has been drastically affected.

Then after the fish tank is opened, if we say, our ornamental fish feeding density is moderate. Then the water is generally changed once a week, because after the previous month of stable water quality, basically you can already see that there are some brown algae on the wall of the fish tank.

And when we touch the wall of the fish tank with our fingers, we can also feel the slippery feeling, which means that some probiotics, such as nitrifying bacteria, have stabilized in the water body of the fish tank.

At this time, it is very necessary for us to change the water once a week, and change the amount of 1 3 1 4 each time. This is the time dimension to measure the water change of our fish tank, which is generally divided into two stages, the first stage is the first month of opening the tank, and then it is the stage after the tank is successfully opened.

If algae appear in the fish tank, the fish are on the surface and breathe, and the water should be changed immediately.

Personally, I think the fish tank should be changed with water once a week. If it is during the change of seasons, it is recommended to change the water every three or four days.

The water change time of the fish tank should be determined according to the situation, under normal circumstances, the water in the fish tank should be changed once a week.
