The water in the fish tank is always green, and after changing the water, it will be green again aft

Bask in the sun, shade out.

The water in the fish tank is due to the timely decomposition and transformation of the nitrifying bacteria of the fish, which makes the ammonia nitrogen in the tank exceed the standard, resulting in the growth of algae, and the growth of moss makes the water green. Innovative Filtration System: Yongqing Filtration System.

It is possible to grow moss in the fish tank. The Yongqing filtration system is composed of a flow pump, a water pump, a biochemical mesh plate, a water pipe, and a filtration tank. The system can lay the bottom sand on the biochemical net, so that the biochemical mesh plate and the bottom sand provide a large area of nitrifying bacteria epiphytic, and decompose and transform harmful substances such as fish excrement in a timely manner through the physiological function of nitrifying bacteria.

The flow-making pump creates a directional flow of water under the mesh plate and directs the precipitated waste to the pumping outlet, where the filtered water flows back into the tank.

The Yongqing filtration system is a combination of upper filtration and bottom filtration in form, and in essence, it is the optimal and perfect combination of physical filtration and biochemical filtration.

The Yongqing filtration system can establish a stable ecological balance in the fish tank. It is perfectly suitable for feeding high-density or large freshwater and marine fish. The system does not need to manually clean the waste of the bottom sand, as long as the filter is cleaned regularly and the water is partially changed, the water quality can be kept stable and clear, and moss will never grow.

Effectively reduce the daily maintenance and cleaning work of fish farming, and also create a favorable environment for the healthy growth of fish. For details, please Yongqing Filtration or Yongqing Water Clan.

<>First, the reason for turning green:

1. Physical causes: Most of them come from decomposed fish feces and undigested plant fibers.

and inorganic salts, etc. In the early stage of fish tank opening and grass tank opening, the water color of the mud tank is generally yellow. This is because our aquatic weed mud is very dry before use, and in the first few days of being blistered in the tank, the mud skin continues to be pulverized, which causes turbidity and yellowishness;

2. Biological causes: microorganisms in water quality multiply in nutrient-rich water. Here I will divide into two kinds of biological turbidity, algae.

Cloudiness and heterooxygen bacteria are cloudy, and most of them are accompanied by the common cloudiness of both.

Second, the governance method:

1. Pour half of the water in the fish tank first, if it is a small fish tank, you can pour it directly; If it is a large fish tank, you can scoop it out with a water spoon, and if there is a water pipe, you can use the water pipe to export. After pouring out half of the water, use a brush to clean the unclean areas in the fish tank;

2. Inject water into the fish tank, if it is still turbid, it should be circulated several times;

3. After cleaning, it is best to purify the water with a filter, so that the water is clear.

If the water in the aquarium turns green, it means that a large amount of algae (green moss) has grown in the water, and it should be removed in time. Algae absorb oxygen at night and release CO2, which reduces oxygen and increases carbon dioxide in the tank, which poses a great threat to the survival of fish.

Solution: 1. Reduce the nutrient content of water.

The solution is to change the water (especially the bare tank), change the water, and then change the water. Filtration is strengthened at the same time as the water is changed, and a powerful nitrification system is used to prevent the production of toxic ammonia nitrogen and nitrite.

2. Avoid sunlight.

Practice has proved that the irradiation of natural light makes the algae grow the fastest, especially the green moss will quickly grow in the first type, take the construction of a pergola to shade, or use newspapers to shade the sun. The fluorescent tubes used in our aquarium lighting can also cause chromatographic incompleteness due to aging.

This causes algae blooms. If conditions permit, you can turn on the UV lamp (ultraviolet germicidal lamp) to cooperate, irradiate for one to two hours a day, and if it is sunbathing, you can add another two hours, which is also very effective.

1.The reason why the fish tank water turns green may be that the light time is too long, which allows the green algae in the fish tank to bloom.

2.At this time, move the fish tank to a semi-shaded place and remove the green algae from the tank.

3.It may also be that there are too many fish in the tank, which produces more impurities.

4.At this time, it is necessary to divide the tank in time to reduce the breeding density.

5.It could also be that too much food is being fed.

6.At this time, it is necessary to clean up the residual feed in the tank in time, change the water appropriately, and reduce the amount of feeding afterwards.

If the water in the tank always turns green, the keeper can try to change the water frequently to improve. As long as the water is clean, there will be no greening.

Also regularly clean up food debris and feces in the fish tank to reduce the waste in the fish tank.

If the fish can't tolerate frequent water changes, it's a good idea to install a filter, which can also slow down the rate of water deterioration.

In addition, the presence of algae in the tank will also turn the water green, so the keeper can try to raise a few fish to remove the algae.

When there is too much algae in the fish tank, the keeper can try to breed fish, shrimp, snails and other organisms that remove algae, so that the algae in the fish tank can be removed, which can not only ensure that the water quality is clean, but also enhance the ornamentality, this method of removing algae is the safest. Keepers can also add some algae-removing drugs to the tank, which can remove all the algae, but algae-removing drugs may have an effect on the fish. In addition to this, it is also important to take care that the light is not too long to avoid algae blooms.

The fish tank water turns green in two days may be caused by too strong light, and the keeper needs to place the fish tank in a hidden place to maintain it to avoid direct sunlight causing the water in the fish tank to turn green. The green water in the fish tank may also be caused by the long-term failure to change the water, and the keeper needs to speed up the frequency of water change. It may also be caused by too many aquatic plants in the tank, and the keeper needs to reduce some of the aquatic plants to avoid the water in the tank turning green.

The water in the fish tank turns green in two days, which may be caused by too much light, and the keeper should avoid direct sunlight in the fish tank. Direct sunlight in the fish tank will cause the green algae in the tank to photosynthesize, which will cause the water in the tank to turn green due to the large number of blooms.

The water in the fish tank turns green in two days, which may be caused by not changing the water for a long time. It is recommended that the keeper change the water every other day and disinfect the fish tank regularly to keep the water in the fish tank clean and thorough.

The water in the fish tank turns green in two days, and it may also be caused by too much water and weeds in the tank. If the density of aquatic plants in the tank is too large, it will lead to eutrophication of the water body, and the breeder needs to reduce some of the aquatic weeds.

The water in the tank is particularly green, probably because the light is too strong, which causes the green algae to bloom. At this time, the fish tank should be moved away from the light. It may also be due to the bloom of algae brought in from the outside world.

In this case, algaecides can be used to remove algae. It may also be because the water contains a large amount of chlorine, so heat and change the water immediately. In addition, too much water can also cause algae blooms.

At this time, it is necessary to change the water in time and reduce the density of breeding.

1. Reason: The fish tank is placed in a place with strong light for a long time, and the algae in the fish tank continue to absorb light and grow and multiply rapidly, causing the water in the fish tank to become particularly green.

2. Method: Place the fish tank away from the light, which can slow down the reproduction of algae. Staying away from light is not about eliminating light, but about reducing light on the basis of ensuring reasonable light.

1. Reason: When feeding live fish and live shrimp to ornamental fish, green algae from the outside world may be brought into the fish tank, and the green algae will multiply in large quantities at a suitable temperature, and the water will appear green.

2. Method: You can put a certain proportion of algaecide in the fish tank, and the green color in the water will disappear after a period of time.

1. Reason: The density of fish cultured in the fish tank is large, the waste excreted by the fish is more, and the water in the fish tank is easy to become fat. In addition, the filtration system in the fish tank is not perfect at this time, which will increase the fertility of the water. As a result, the green algae bloom and the water in the tank will become particularly green.

2. Method: Fish farming must ensure sufficient space and clean up the fish feces in the water in time. It is best to install a filtration system in the fish tank, so that the water quality can be maintained and water fertilizer can be avoided.

1. Reason: The chlorine in the water is not filtered out when the new water is replaced, and the excess chlorine will make the water in the fish tank become particularly green.

2. Method: Increase the water temperature. You can use a heating rod to heat the water in the fish tank, which can quickly remove the chlorine in the water and restore the water to its normal color. In addition, you can also change the water in moderation.

Answer Hello Dear!! The environment that can produce green water is generally very well lit, it may be that there is too much sunlight, or it may be that the fish tank light is turned on for too long, so that the time for chlorella photosynthesis becomes longer.

Now that we know that chlorella grows on light, let's take the right medicine and reduce the light. You can place the fish tank in an environment with insufficient light, and if there are aquatic plants in the tank, then we will take measures to turn on the lights to ensure that the aquatic plants grow well. However, the fish tank light should not be turned on for too long, do not exceed 10 hours a day, it is easy to grow algae if the light is turned on for too long, not only chlorella, but also other algae.

Find a clean, coarse fiber cloth, place it on the top layer of the filter, and then turn the filtration flow to the maximum for it to filter. Filter until the whole cloth has turned green, take it out and wash it, and then put it back for filtration, and so on and so on, wash it when it is dirty, wash it, wash it. After a few hours, the water will slowly become clear.

I've tested this method very well and it doesn't affect the nitrifying bacteria system.

Friends who don't like green water usually need to pay attention to prevention, green water production actually needs nutrients, if the filter bin accumulates a lot of nutrients and does not clean it up, it will be easy to breed algae, so we adopt the rule of changing more cotton and feeding less.

Green water is actually the water quality that many goldfish players dream of, because green water is good for goldfish hair color, and it is relatively mild, so if you don't dislike it, you must not clean it up.

The water in the fish tank turns green mainly because there are a lot of chlorella, but it is not too harmful to the fish, but it will affect the ornamentality, if you want to remove it, you should change the water regularly, and you can also raise some clean fish, such as scavengers, they can eat the algae in the water.

If this happens, of course, you need to change the water, you can clean the fish tank first, and then change the water.

In this case, we need to change the water quickly. If the water is not changed, then there is a high chance that the fish will be infected with some bacteria, causing the fish to die.

Change the water in time, you can raise some small fish and shrimp that eat algae.

Fish tank water turns green causes and solutions. In the process of raising aquariums, it is often found that the water in the fish tank is getting greener day by day. There is no way for breeders to shorten the cycle of changing water, but no matter how often you change the water, you can't escape the result of water green, so the breeders have one head into two big.

To solve the problem of the water tank turning green, we must first find the cause of the greening, and then solve it in a targeted manner.

Reasons why the fish tank turns green.

1.Excessive light exposure in the fish tank causes a large number of green algae organisms to multiply. Floats in the water, adheres to the walls of the fish tank or the surface of aquatic weeds, and turns the water green.

2.The proportion of fish and aquatic weeds in the fish tank is unreasonable, and the capacity of the fish tank is too dense. As a result, the filter cannot completely filter pollutants, which is the pollution of the water quality and environment, and at the same time, it will also cause the growth of green algae organisms too fast.

Resolution. 1.Shortening the light time in the fish tank, the lack of sufficient light will slow down the growth rate and reduce the number of green algae.

2.Improve the filtration system in the fish tank, enhance the speed and efficiency of pollutant treatment in the fish tank, reduce the nutrients for the growth of green algae, and slow down the time for the water to turn green.

3.A few scavengers can be kept in the tank, and this fish is fed with green algae, which can effectively reduce the number of green algae.

4.Change the fish with new water in time, and clean the fish tank and aquatic weeds to remove green algae on the surface.
