Why does the water in fish farming turn green What happens when fish farming water turns green?

<> goldfish (details).

We know that water quality is a major factor for fish farming, and sometimes we encounter the situation that the water quality turns green in the process of fish farming, why is this? Is green water not suitable for fish to grow? 

If the water in your aquarium turns green, it means that there is a lot of algae (green moss) in the water and it should be removed immediately. 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. If the fish tank is large and there are few fish, or the outdoor fish pond is not a big problem, as long as you think it will not affect the viewing.

In the process of raising ornamental fish, sometimes we like to make the water green, green water is good for 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 possible, you can turn on the UV lamp (ultraviolet germicidal lamp) with one to two hours of irradiation every day, and if it is sunbathing, you can add another two hours, which is also very effective.

Not all water can meet the needs of goldfish, the most suitable water for goldfish growth is old water, the so-called water is the process of transforming new water into old water. 

It should also be told that old water is what we are after, and in the case of goldfish, green water also has many benefits for goldfish. For example, green water can make goldfish darker, but there are too many algae in this water, and you can't see the fish, not and watch. 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. 

There are many possibilities for water to turn green and muddy.

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. Overfeeding, the fish can't finish the feed, the feed rots in the water, and the water quality is over-trophied, so that ammonia and other substances accumulate in the water faster, and the nitrifying bacteria are passed.

It is converted into nitrate, which is an important fertilizer for aquatic plants and algae, and if the water contains a lot of nitrate, algae will grow wildly.

4 The nitrification system is declining, and if the nitrification system is not functioning properly, algae will grow wildly, turning the water green and muddy. This means that if one species is strong, the other will be weak.

It is recommended that you change the water again, maintain the water, and establish a nitrification system.

If there is green algae on the wall of the fish tank, you can raise one or two scavengers.

Come and eat green algae. Algae shrimp, black-shelled shrimp.

or apple snail (Fushou snail.

You can also. 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.

The green color of the water in which goldfish are raised is due to the increase in algae in the tank. And there are two sides to whether this situation is good or bad. To put it simply, a moderate amount of algae is undoubtedly the most suitable for fish survival, which is also very good for the life of goldfish (as the saying goes, if the water is clear, there are no fish).

But be sure to control the rate at which the algae bloom.

The water temperature is suitable, the circulating pump is not strong enough to remove the fish feces cleanly, the water is not changed frequently, and the sunlight is good, these are the suitable conditions for the growth of algae.

<> the water in the fish tank turns green, it may be caused by the aging of the water quality after not replacing the water for a long time, and the water in the fish tank needs to be replaced in time at this time, but it is best not to replace all at once, otherwise the fish will not adapt to the situation. In addition, some algae-eating organisms can also be kept in the fish tank, which can also inhibit the growth of green algae.

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.

5. You can add some hydrogen peroxide appropriately to remove the green algae in the fish tank.

1.The water in fish farming turns green because of chlorella blooms.

2.This kind of water is also called green water, although it does not look very clear, but it is not very harmful to fish, on the contrary, it can also be used as food, but also can absorb ammonia nitrogen in the water.

3.If you want to raise green water, you need to ensure light and control feeding, which not only plays a maintenance role, but also avoids a large number of algae explosions, so as not to pollute the water quality after pouring algae.

1. Change the water frequently. First of all, change the water frequently, and wipe the glass clean at the same time, as fish excrement and fish food will cause the water in the bathtub to change color over time.

2. Raise a scavenger. You can keep a scavenger", and a scavenger can clean every corner of the inside of the bathtub very well. Pirang is also a good choice for lazy people.

3. Feed a small amount. Some fish food will add pigments to increase the color of goldfish. Fish food can change color when left in the water for a long time.

So try to feed as little as possible. The temperature will also cause the water quality, the heating rod and the lights, and the lights will be dimmed. If the temperature is not very low, you can turn off the heating bar.

Configure filters in addition. Change the filter cloth frequently.
