Why is the water in the goldfish bowl at home green?

Generally, the water turns green and muddy because of the following possibilities.

1 If the light is too strong, the green algae in the water will continue to grow, so the water will turn green. Now the only way to do this is to change the water to shade the fish tank, which cannot be placed by the window and let the sun shine directly.

2. The fish tank is not large, there are too many fish or the power of the filter is small, and the dirt cannot be completely filtered, and the green algae will grow quickly.

3. Feeding too much, the fish can't finish the feed, the feed rots in the water, the water quality is over-trophied, so that the water accumulates ammonia and other substances faster, and after nitrifying bacteria, it will be converted into nitrate, nitrate is an important fertilizer for aquatic plants and algae, if the water contains a lot of nitrate, the algae will also grow wildly.

4 The nitrification system declines, if the nitrification system is operating normally, the algae will not grow like this, only when nitrification is not working, it will be like this. This means that if one species is strong, the other will be weak.

It is recommended to change the water, raise the water, and establish a nitrification system.

If there is green algae on the wall of the fish tank, you can raise a scavenger or two to eat the green algae. Algae shrimp, black-shelled shrimp or apple snails (Fushou snails) are also available.

5 The fish tank is large, but the power of the filter is not enough, or the fish tank is small and the fish density is too large, which will make the water muddy quickly.

Solution: 1 Keep the fish tank away from sunlight and use a fish lamp instead.

2 Change the water in the morning and in the evening The amount of water pumped each time is one-fifth of the whole.

3 Add a filter to the fish tank, I recommend you to use a Jiabao external filter.

4 There is a special water filter for fish farming in the market.

How to use: Sprinkle the body evenly into the tank according to the proportion of your fish tank, and let the filter filter to filter out impurities.

5 Wipe the inner wall of the fish tank with a cotton cloth regularly.

The green color of the water is due to the large number of algae growing in the water, and it is not easy for the algae to multiply after the fish tank is thoroughly cleaned, and then replaced with water and placed in a dark place.

There are algae water fish is very good, the fish will be healthier, but the water should not be too green, (if the green to black fish is harmful) and the silver dragon is a tropical fish, the koi is a cold-water fish, they can not be raised together, if they are kept together, the water temperature must be in the same moderate range, in the current temperature changes greatly, the koi have a strong ability to adapt to temperature mutations, and the silver dragon is not necessarily, and if you are a novice, don't raise too expensive fish first, first raise cheap (cold water: goldfish, koi, etc., tropical: peacock, Mary......）

Suggest: Silver Dragon, Koi Fish, etc.

The above is a personal opinion.

The reason why the water in the fish tank turns green is that the light time is too long, the proportion of fish and aquatic weeds is unreasonable, and the fish are fed too much.

1. The light time in the fish tank is too long, which leads to the reproduction and growth of a large number of green algae organisms. 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, so that the water quality environment is polluted, and at the same time, the green algae organisms will grow 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 raise a few scavengers in the fish tank, which 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.

The green turn of the water in the goldfish tank is usually caused by the green algae growing too fast in the tank. If the light is too strong, the tank is too small, the feeding density is too large, the food is too much, or the nitrification system in the tank is not functioning, the green algae will easily grow, and the water in the tank will easily turn green. If the water in the tank turns green, you can change the water first, reduce the breeding density appropriately, and cultivate nitrifying bacteria in the tank.

If that doesn't work, keep a scavenger fish or two in the tank to help clean up the green algae. <

The green color of the water in the goldfish bowl is caused by the wild growth of green algae, and there are several reasons for this:

1. The light is too strong: When the light is too strong, the green algae in the water will grow faster, so the fish tank cannot be exposed to direct sunlight.

2. Feeding density is too large: when the fish tank is too small or the fish feeding density is too large, there will be more debris in the water, which will lead to the crazy growth of green algae.

3. Feeding too much food: If the feeder feeds too much food, the fish will not be able to eat it, which will cause the food to rot in the water, thus turning into nutrients for green algae.

4. Abnormal nitrification system: When the nitrification system is in trouble, green algae will also grow quickly.

If you find that the water in the fish tank is turning green, you can take the following methods:

1. You can raise two scavengers in the tank, which can have a better cleaning effect.

2. Change the water again and strengthen the filtration in the tank. Try to keep the water fresh every two days, don't change too much water at a time, and keep it at a quarter. In addition, the filter should not be changed too often, because it can promote the establishment of the nitrification system and also facilitate the reproduction of nitrifying bacteria.

We know that for fish farming, water quality is a major influencing factor, sometimes in the process of fish farming, we will encounter the situation that the water color turns green, and when it is serious, the fish in the fish tank are looming, and even the fish will die! Why is that? Is green water not suitable for fish to grow?

Not all green water is not suitable for fish life, goldfish are very suitable for breeding in green water.

If the water in your aquarium turns green, it is a sign that there is a lot of algae (green moss) in the water and needs to be removed. Because the algae will absorb oxygen at night and release CO2, the oxygen in the fish tank will be reduced, and the carbon dioxide will increase, which will greatly reduce the amount of dissolved oxygen in the fish tank water, which poses a great threat to the survival of the fish. If there are no large fish in the fish tank, or the outdoor fish pond is not a big problem, because the outdoor fish pond is strong and long, and the moss cannot be completely **.

In the process of raising goldfish, we like to make the water green, because green water is still good for the fish; Sometimes they don't want it to turn green, and the water turning green not only affects the ornamental, but also deteriorates the living environment for the fish. There are actually many ways to control the greening of water bodies, and here is a brief introduction:

1. Reduce the nutrient content of water.

This is a headache for many aquarium masters, and 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, which can cause 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.

I believe that some aquarists should know that it is very good to raise goldfish in old water, and the appearance of old water looks green and yellowish.

Old water is what we are pursuing, but it is very important to raise water in the early stage of fish farming, which is the process of transforming new water into old water. Green water also has many benefits for goldfish. For example, green water can make goldfish darker, but if there is too much algae in the water and you can't see the fish, this is not suitable for viewing.

And when there is too much algae, the fish will lack oxygen, so it is necessary to pay attention to controlling the amount of algae in the water when raising goldfish in green water. Technology is needed.

When you see that the water quality in the fish tank has changed, you can change the water in the fish tank, but you must pay attention to leaving some old water when changing the water. If the water in the tank turns green, you may need to clean up the algae inside in addition to replacing the water. So what should I do if the fish tank is green?

1.Chlorella multiplies and grows. Sometimes the light in the fish tank is too long, which will cause a large number of green algae organisms to multiply and grow. They float in the water and adhere to the walls of fish tanks or the surface of the leaves of aquatic plants, turning the water green.

2.Water quality and environmental pollution, the proportion of fish and aquatic plants in the fish tank is unreasonable or too dense, so the filter can not completely filter out the pollutants, pollute the water environment, and green algae will grow too fast.

1.Shorten the lighting time of the fish tank. Lack of adequate light exposure for green algae slows down growth and reduces numbers.

2.Improve the filtration system in the fish tank to increase the speed and efficiency of contaminant treatment in the fish tank, reduce the nutrients needed for green algae growth, and slow down the time it takes for water to turn green.

3.You can keep some scavengers in a fish tank. This fish feeds on green algae, which can effectively reduce the number of green algae.

4.Replace the fish with fresh water in a timely manner, and wash the fish tank and aquatic plants to remove green algae from the surface.

The water quality in the fish tank turns green, which is not conducive to the life and growth of the fish. When it is found that the water quality of the fish tank has turned green, it must be treated in time to avoid the death of a large number of fish due to the destruction of the water environment.

In fact, it is relatively simple to replace the water in the fish tank. Usually, when the water quality deteriorates, the water can be changed. Each time you change the water, replace only a quarter or a third of the tank.

Because there is so much new water, the fish cannot adapt to the current environment and are prone to disease. During the summer months, it is usually replaced about twice a week. Before changing the water, let the water sit for a while to remove residual chlorine from the water.

You must consider your own situation when changing the water. The amount of water to be changed is related to many factors, such as breeding density, amount of bait, size of the fish and size of the tank. These factors can also affect your water transfer. Therefore, it is necessary to change the water according to the actual situation.
