How can you keep fish in a tank without having to change the water frequently?

That's not going to work. Fish will die if the water is changed too often, but fish will also die if the water is not changed for a long time.

First of all, it depends on how big the water tank is, the density of fish in the tank is too large, and the fish will die due to lack of oxygen, so the number of fish should be appropriate, and it should be equipped with oxygen supply equipment to supply oxygen to the fish tank in time.

Secondly, if you are a little lazy and want to change the water for a long time, you can give the fish less to eat, and eat too much, which may kill the fish, and if the fish can't finish eating, it will also be blistered and sink to the bottom of the water, polluting the water quality. Give the fish less to eat, so that the water is more turbid and slower, and the interval between water changes can be longer.

However, if the water becomes very muddy and the fish are not changed, the fish will die quickly, so don't be lazy.

According to the experience of my grandparents, the water for the fish should not be directly connected to the tap water, but the water should be connected in advance, let it stand in the basin for a few days, and then change the fish, otherwise the fish will die easily.

I believe that there are many friends who like to raise a few goldfish in their own homes to increase the atmosphere of the family.

Some people also focus on Feng Shui because fish have a great effect on Feng Shui.

But the biggest trouble with fish farming is the problem of changing the water in the tank, which is very headache.

It's easy to add water to the tank, but it is very laborious to completely remove the water from the bottom of the tank, and it is also necessary to clean the dirt on the surface of the tank.

So how can you keep fish in a tank without having to change the water frequently?

You can simply make a little design and make a water circulation system above the cylinder port, and that kind of small water pump is sold online or in physical stores.

The water pump is placed directly on the bottom of the water, and the water pipe is connected to the water tank to make a flowing rockery, which is also sold in some fishing tackle stores.

When the water pump leads the water to the rockery, the rockery flows down the water, and at the same time, a water tank is made at the bottom, and some sponges are placed in the sink to filter the debris in the water.

As long as you change the cleaning cotton regularly, you can maintain the cleanliness of the water in the tank for a long time.

You can also buy a few scavengers and put them in the water, which are all good methods.

It seems that you still need me to answer for you how to solve this problem. There's plenty of space in your tank to keep these fish, and the problem is filtration and feeding. It can be done without changing the water for a long time, but it is not good for the healthy growth of the fish.

If you want to not change the water for a long time, you should not feed too much, and you should strictly control the amount, and a small amount can be used once a day. If you feed normally without changing the water or in excess of water, of course you will turn yellow. Your filtration must be not enough biochemical processing power, as for whether the physical filtration effect is good, I don't know if I don't see the real thing.

Generally, if you want to make the water quality of the fish tank stable, the ideal filtration capacity should be more than one-third of the water capacity of the fish tank, of course, most people can't do it, so a quarter is almost, no matter how small it is, you need to change the water frequently and are tired and panicked, and the water quality is easy to fluctuate violently, making the fish easy to be nervous and sick. The filtration is large enough to achieve long-term water without changing the water, as long as the feed is less fed. The stability of water quality requires the filtration of various bacteria such as nitrifying bacteria attached to the filter material to deal with garbage, of course, the more these bacteria, the better, and the only way to do this is physical expansion filtration.

If you can only use the so-called filter box (that is, the kind that is very small), then there is no good way except for your diligent washing physical filtration and water change, that's it, and you can't overfeed, because there is too much garbage and the number of bacteria is not enough, and the yellowing of the water quality is caused by too much feed dyeing and the other is caused by too much waste in the water to be treated, and the fish will get sick after a long time. It seems that you want to save trouble and worry less, so you can only spend money in exchange for your ease, and rebuild the largest filter device possible. I'm like this, I have a ton and a half of water in my fish tank, the filter box can hold 400 kilograms of water, I open the filtration and oxygenation equipment 24 hours a day, I often forget that I don't change the water for a month or two, and the fish is no problem, the water is definitely going to yellow if it is too long, I raise koi, and I can eat more than your fish size.

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.

Fish tank water change method:

1. The lid on the top does not need to be opened, the water pump should be opened 24 hours a day to change the water in the fish tank, so wipe the inside of the tank with a rag, and then use the filter pump to circulate and filter or use the pipe to pump the booty at the bottom of the water and then change it to 1 3 water.

2. Using the principle of water pressure, insert one end of a hose into the fish tank, and insert the other end into the water exchange basin. Then suck the hose nozzle at the lower end, and the water in the tank will flow downstream. Then slowly pour the prepared fresh water into the fish tank.

It is recommended to change the water every 3-4 days 1 3-1 4. Fresh water should be left for about 3 days.

When you need to change the water:

1. When the water in your fish tank appears turbid, white, yellow, or green.

2. When you can't filter the fish feces to clean up.

3. If you are raising fish such as pearls or silver dragons in Luohan, then there is no need to change the water! Because your fish like it.
