Excuse me, why does the water in the fish tank turn green just 2 days after changing?

No matter how often you change the water, you can't escape the result of the water, so the breeders turn 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. The light time in the fish tank is too long, resulting in a large number of green algae.

Organisms reproduce and grow. 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. Shorten the light time of 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, strengthen 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 quality to turn green.

3. You can keep a few scavengers in the fish tank.

This fish is fed with green algae, which can effectively reduce the number of green algae.

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

When the water quality in the fish tank turns green, it is not conducive to the life and growth of the fish, when it is found that the water quality of the fish tank turns green, it should be treated in time to avoid a large number of fish dying due to the destruction of the water quality environment.

Is it that the fish tank is too small, or that there are too many fish.

It may be that the water quality is not good, which is normal.

Green water isChlorellaThe phenomenon of rapid reproduction is called algae bursting. Please check if there are any of the following:

1. Plenty of sunshine. It doesn't have to be direct sunlight, too bright sunlight can also promote green algae growth, don't keep the fish tank too close to the window.

2. The water is too fertile. The density of fish is high, feeding more, the water is muddy fast due to high temperature in summer, and the abundance of nutrients leads to the outbreak of green algae, reducing the density of fish, reducing feeding, and changing the water frequently.

Chlorella have photosynthetic pigments, and typical green algae cells may or may not be motile.

Cells** have vacuoles.

Pigments are distributed in plastids, and the shape of plastids varies with species. Cell wall.

It is composed of two layers of cellulose and pectin.

The green water in the fish tank may be caused by long-term light, or the feeding density is too small, it is recommended to shorten the light time of the fish tank and increase the feeding density appropriately. However, it is also possible that due to excessive feeding, the residual food decays in the water, which accelerates the reproduction of green algae, and it is necessary to carry out a small amount of multiple feeding methods at ordinary times, which can gradually improve the situation of water turning green.

The water in the fish tank will turn green in two days, probably because the fish tank has been exposed to light for a long time, which has caused a large number of green algae to grow. It is also possible that the water quality is polluted because the stocking density is too small to be filtered in time. When too much fish is fed, the water will turn green.

When the water in the fish tank turns green after two days, you can shorten the light time of the fish tank as much as possible and move the fish tank to a ventilated position. Increase the density of feeding, so that the filtration equipment can filter debris better and faster, and keep the water quality clear.

When the fish are fed too much feed, the fish will not be able to eat enough, which will cause the residual food to rot and deteriorate under the water, and accelerate the intensive growth of green algae. It is recommended to feed a small amount of food many times at ordinary times, and when the fish do not grab food, it means that there is no need to feed again, and gradually the water will not turn green.

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.

Reason: A large amount of algae grows in the fish tank, which is green moss.

Solution 1: When you find that the fish tank is starting to show signs of greening, it is a simple and safe way to change the water properly. This is because changing the water will not hurt either party in the tank. When changing the water, pay attention to strengthening filtration.

Solution 2: Try to avoid direct sunlight, which will speed up the growth rate of green algae, which is very reproductive. If the aquarium lamp is aged, it can also cause algae growth.

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.
