Is it reliable to keep a fish tank without changing the water and maintaining it?

I haven't changed the water for more than a year, just a day or two days to make up for the loss, but the filter material is still cleaned regularly, otherwise the black algae will burst, let me explain, I haven't changed the fish, just because I've seen enough. I'm also lazy and want to change fish, so I breed it like this. Novices raise dead fish no matter how they go, and veterans basically don't take care of them, so there is no problem, and they are very helpless.

I'm not diligent in feeding, just a little bit a few days. Sometimes I don't feed once a week when I'm lazy. (At the beginning of fish farming, I changed the water and cleaned the filter cartridge once a week, nitrifying bacteria everything, the dead fish were too powerful, the whole army was wiped out a few times, and I slowly felt very tired, so I didn't pay attention to so much) I haven't bought nitrifying bacteria for several months, and there is no green algae in the tank for fear that those beards will starve to death.

Too lazy to feed them. CO2 is always there, and the lights are turned on at the same time. If you want to raise fish well, it is really unreliable not to change the water, and you want to raise fish, this kind of free water change, maintenance-free is not to say no, I personally feel that the business is only to catch people lazy, but want to raise fish This idea of copywriting planning.

This is very unreliable, because the fish will discharge some dirty things, and after a long time, the fish tank will be very dirty, so it is recommended to change the water for a long time.

It's impossible not to change the water, think about how people have to go out every day for a change of air, and you can't stand it if you don't go out for several years in a house. I think it's better to change the water regularly in order to make fish farming fun, beautiful, and care about the fish. As for the fish tank without changing the water, it is just a gimmick.

Theoretically, it can be done, but such a fish tank will definitely be very expensive, and it is better to manually change the water for maintenance.

My tank is a meter high, but I don't worry, 5 years in addition to about 3 months to change the cotton, a week to add a little water, never moved, the fish has never died, I raised Congo beauty, apple beauty, a group of head and tail lights, and 5 river shrimp, two elf rats, a big sunken wood in the tank.

There are several different steps in fish farming, feeding, raising well, rearing essence, breeding, and even regular breeding, may I ask what your criteria are. If you stay in the stage of feeding, you can not change the water, and believe in the so-called water-free ecological tank. But if you have higher requirements, try to change the water.

Theoretically speaking, fish tanks that do not need to be changed and maintained are more reliable, because the quality is really ***.

It is possible to raise fish all year round without changing the water, but it is not a fish tank like him, I don't need to change the water when I raise fish at home, and I haven't changed the water for several years, why? The water filtration system is very important, this filter box plays a key role, if there is no it, the fish tank will not be able to resist two days will become turbid, and even become smelly, the problem that this closed-loop circulation filtration system needs to solve is the following points, remove the harmful substances of fish poop, filter fish poop, increase oxygen content, sterilization, when you solve these items, the water in the fish tank is indeed clear all year round and do not need to replace the water, but you need to replenish the evaporated part of the water.

Yes, I use a fish tank that does not need to be cleaned, but it is relatively more energy-intensive because it has a large water circulation.

As a professional player who has been raising 1,000 tanks for 17 years and feeding 1,000 tanks at the same time, I think it's true that they say they won't change the water, but they don't say they won't change the fish. First of all, it is true that there are many aquarists who do not change the water when they raise fish, but this is only a product of individual circumstances and specific conditions. For example, there are not many fish, the species are different, or the feeding amount is not large, and the fish are relatively beginner, and then there are very low requirements, and they feel that feeding is success, or they have these conditions at the same time.

Let's think about it from another angle, for example, can raising 100 peacocks in a tank of one meter be the same as raising 20 parrots or on the map? For another example, a tank of hormone sea bream with less than 500 pieces of fish, and a tank of high-end wild vegetables, can the hormone sea bream not change the water, can the wild vegetables? So considering the thorough problem, I think it is better to consider the practicality of the fish tank before deciding whether to buy it.

I think that the aquarium (glass fish tank) should be changed regularly, and the goldfish in the porcelain pot do not need to be changed. (Resting tap water).

Not changing the water is a gimmick, the tank can automatically replenish water according to the water level, realize the water change, or add water by dripping, in fact, they are all changing the water, and the saying is different.

To believe in the power of science and technology, there is nothing unreliable, professional fish farmers and fish sellers do this!

The fish tank should be brushed to change the water. In the process of fish farming, we also have to do an important jujube lifting work will be to clean the fish tank. Whether it is an expensive or cheap fish tank, there will be some algae on the wall of the tank.

For example, green algae.

There are also brown algae. The presence of these things will affect the ornamental value, so we have to remove the stool Yubi, so that the fish tank becomes clear and transparent, and the fish seen are also very clear.

Water change method:It is generally not recommended to change the water in large fish tanks. The full tank water change is only carried out after the fish is sick, and in the usual management, the large fish tank should be avoided as much as possible.

The full tank water change is only carried out after the fish is sick**, and in the usual management, the large fish tank should be avoided as much as possible.

The correct water change should be to only pump out the sediment at the bottom of the fish tank, and change about 1 3 of the total water volume of the fish tank each time.

1. The water-free fish tank does not always need to change the water, but achieves the purpose of water purification through scientific and technological means, and does not need to change the water for a long time;

2. The product adopts three filtration methods of water purification: biological filtration, mechanical filtration and chemical filtration;

3. Biological filtration is mainly the use of input fiber cotton, biochemical cotton and other filter materials adsorption effect, filtration of impurities and metal salts in the water, is the main method of decontamination and water purification, biological filter stone implanted in the aquarium after a large number of microorganisms after cultivation and screening and ready-made specific construction and control means to provide the best living conditions, so that the microbial population always maintains sufficient number and vitality, so that the pollutants in the aquarium can be decomposed in time, the harmful substances are decomposed into harmless substances, so that the aquarium can.

Fish farming requires regular water changes. If the water is not changed for a long time, a lot of fish metabolic waste and leftover fish food will remain in the water, thus breeding bacteria. In addition, the dissolved oxygen in the water will also be reduced, which will not be able to meet the needs of fish growth.

Over time, the fish will get sick or even die. If there is a good nitrification system and filtration system in the fish tank, and there are some aquatic weeds, then the frequency of water change can also be appropriately reduced, but the water can not be changed. <

In the process of fish farming, ensuring water quality is an important task, and only in this way can the fish grow healthily. Regular water changes are an important measure to ensure water quality. Generally speaking, the water needs to be changed regularly in the process of fish farming.

If the water is not changed for a long time, the water quality will become very poor, and bacteria will grow in the water, which may cause fish to get sick and affect their healthy growth.

However, if you find the process of changing the water more troublesome, you can also take some measures to reduce the frequency of water changes. There are three things that need to be done. The first is nitrifying bacteria, and there need to be enough nitrifying bacteria in the fish tank to establish a complete nitrification system.

This system breaks down some of the organic matter and nitrates, which purifies the water and makes it clear. Second, a filter should be placed in the fish tank, or a well-functioning filtration system should be established, and the filter cartridge should be cleaned regularly afterwards. In addition, some aquatic plants should be planted in the fish tank, which can release oxygen and optimize the ecological environment in the fish tank.

As mentioned above, it is generally necessary to change the water regularly when raising fish, but it is also possible not to change the water, and appropriate measures must be taken at this time. If there is an excellent nitrification system and a strong filtration system in the fish tank, and there are some aquatic plants in the water, then the water can not be changed, and there will be no harm at this time. However, if the various settings and equipment in the fish tank are not perfect, and we do not pay attention to the regular change of water, then the water quality may gradually deteriorate, and the oxygen in the water will continue to decrease, which will cause harm to the health of the fish in the long run, and even lead to their death.

If the fish tank does not change the water for a year, the fish tank will not change the water for a long time, which will lead to the accumulation of a lot of toxic substances in the water, which is not good for the health of the fish and is easy to make the fish suffer from diseases. The frequency of changing the water in the fish tank once every half a month is the best, and the frequency is too high or too low to harm the fish. The new water needs to be dried before it can be replaced.

It is not possible to change the water in the fish tank for a year, and the water quality will deteriorate if the fish tank is not changed for a long time. Toxic substances accumulate in the water, which is not good for the health of the fish in the tank and can cause diseases in the fish.

The frequency of changing the water in the fish tank is controlled once every half a month, if the frequency is too high, it will cause the fish to have a stress response, resulting in disorder and disease. If the frequency is too low, toxic substances accumulate in the water, which affects the health of the fish.

Proper water change is also a necessary part of the management of fish farming.

How to control the amount of water change?

First of all, it is clear that the water change of the whole tank can only be carried out if the fish is treated, and the water change of the whole tank should be avoided as much as possible in the usual management. Because the fish have adapted to the water quality in the tank, changing the water in the tank will cause a sudden change in the water quality, making it difficult for the fish to adapt, and the old water environment will also be damaged. This is a very important reason why many novice fish cannot be raised.

In addition, changing the water in the whole tank is also a waste of time and water resources.

So how do you control the amount of water you change? Differentiation should be made based on factors such as the species, density and filtration conditions of the fish being farmed. For bare tanks, it is best to use a siphon to suck out the dirt at the bottom of the tank every day in combination with a water change, and add an appropriate amount of fresh water.

For the water plant tank, the water can be changed 1-2 times a week, and the special suction pipe can also be used to suck out part of the dirt in the sand, and the water exchange per week is about 1 5-1 2 of the total water volume. For different water quality conditions and different fish species, the number of water changes and the amount of water changes should also be different. If the fish density is large, the volume is small, and the water quality is easy to turbidize, it may need to be filtered day and night, and more water may be changed every day.

If the betta fish has a small amount of activity and likes old water, it should reduce the number of water changes and the amount of water exchange. The specific amount of water and the number of water changes often need to be experienced in the management of a fish tank for a long time.

For straw tanks, the amount of water should not be more than 1 3 at a time, and less for bare tanks. If you feel that the tank you manage needs to be changed by 1 2 per week, then you should divide it into at least two changes. The general principle is that the number of times can be as high as the amount of water should be small.

Stabilizing the water quality at a suitable state for the fish species is our ultimate goal.

What kind of water to change?

What are the requirements for water? Of course, the most basic thing is the water suitable for fish farming. Tap water should be dried or dechlorinated.

If you raise fish with high water quality requirements, the hardness of the water can be reduced by mixing it with boiled water; If the pH is not suitable, you can adjust the pH level environment to the desired pH value with pH raiser and pH lowering agent.

When changing the water of the fish with salt, the amount of salt should be calculated according to the amount of water exchanged, and then added to the tank after dissolving in the added water. It should be noted that the amount of water sucked out of the tank tends to be slightly less than the amount added due to evaporation. If the amount of salt is calculated according to the amount of water added for a long time, it may lead to a continuous increase in the salinity in the tank.

No, if you don't change the water, the oxygen in the water will be absorbed by the fish. Oxygen in water means that oxygen is dissolved in water, oxygen is insoluble in water, but it will always dissolve a small part. Because the bubbles in the water are the oxygen brought in from the air, if there are no bubbles, it proves that there is no oxygen in the water, so the fish tank should be oxygenated.

The principle of oxygenation in feed water is to dissolve oxygen in water through the flow of water in contact with air, the larger the contact area between water and air, the higher the efficiency, if the water is just flowing in the water pipe and not in contact with the air, it is useless. If you want to increase the amount of dissolved oxygen in the water, you can increase the solubility of oxygen in the water, and you can increase the contact area between oxygen and water, and the water pump can quickly replenish or cool down the oxygen in the water after it is consumed.
