Why do tropical fish at home slowly turn yellow in the water?

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 nitrification.

That's when it doesn't work. 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 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.

I think the most likely thing is that there is too much feed to feed, the fish can't finish eating, the feed slowly rots in the water, and the fish tank is not cleaned well, so that the water quality in the fish tank is over-trophied, resulting in faster accumulation of ammonia and other substances in the water, and the nitrification of nitrifying bacteria is converted into nitrate, nitrate is an important fertilizer for algae, if the water contains a lot of nitrate, then there will be a lot of algae, causing the water to slowly turn yellow.

Overheating the water temperature of tropical fish can have a number of negative effects on fish luck, including:

1.Illness or even death: The suitable water temperature for tropical fish is generally 20 to 30, but different species of tropical fish have different water temperature requirements.

Some fish may be able to tolerate a water temperature of around 10, but such as swallow fish and tiger skin fish, will die when the water temperature drops below 18. Therefore, the base carrying beam should try to keep the water temperature constant, and avoid too high or too low water temperature.

2.Decreased immunity: High water temperatures can affect the immunity of the fish, making the fish more susceptible to diseases.

3.Abnormal behavior: In high temperatures, fish may exhibit abnormally recessive behaviors, such as irritability, non-stop swimming, etc.

4.Metabolic disorders: High water temperatures can cause metabolic disorders in fish, which can affect their normal growth and development.

5.Gill damage: High temperatures in water can cause damage to the fish's gills, which can affect their ability to breathe.

Therefore, maintaining the right water temperature is essential for the health of tropical fish.

When the water in the fish tank turns yellow, alum can be added to make the water clear.

Water yellow is your filtration system has not been established, "there is a trace of white flocculent (as if there is a white powder melted in the water)", this is a typical water mold, it is recommended to reduce the water temperature, because you are raising goldfish, it is best to control the water temperature at about 12 degrees, add some salt, water mold is a fungal infectious disease.

1. Water pollution

If the water quality is not good during fish farming, fish manure and leftover feed will accumulate, which will lead to the deterioration of water quality. Bacteria and other organic matter in these debris will increase the turbidity of the water and cause an unpleasant odor on the surface of the water. The turbidity of the water in fish farming may be due to the decrease in the pH level of the water, which is different in each water and should be kept constant in fish tank culture.

When maintaining the fish tank, you can monitor the changes in water quality through tools such as water thermometers and pH test strips and make timely adjustments. In addition, frequent replacement of fish water is also one of the effective ways to improve water quality.

2. Insufficient light

In the case of insufficient light, the plants under the water cannot produce enough nutrients, and the water used to raise fish turns yellow. Maintaining sufficient light at all times is one of the keys to maintaining water quality in fish ponds. Artificial light sources can provide sufficient light to meet the photosynthesis needs of small fish.

Under the sun, the sunlight promotes the growth of plants, and the water of the fish pond becomes clearer.

3. Excessive fish farming

Too many fish will only cause a sharp drop in the water quality in the pond, and over-raising of fish is also one of the reasons for the yellowing of the pond water. The excrement spit of the fish in the pond not only pollutes the water quality, but also consumes the oxygen in the water, increases the pressure in the water, and then affects the environment in which the fish live in the pond. In order to keep the water quality in the fish tank clean, at least 1 liter of fresh water is needed in each pond, and the appropriate amount of fish is controlled.

4. Lack of aquatic weeds

Aquatic plants can be a good helper in the fish tank to regulate water quality, it can convert chemicals in the water into useful nutrients, effectively reducing water pollution. In addition, the growth of aquatic plants can also use carbon dioxide to regulate the amount of dissolved oxygen in the water, absorb and degrade the waste in the water. At high levels of oxygen consumption, they are able to increase the oxygen in the water of the stool.

If there is a lack of aquatic weeds, the color of the water in the fish tank will become darker, which will also increase the risk of yellowing.

1.The water of fish farming is yellow but very clear, indicating that the water is yellow caused by the discoloration of some things, and it may also be that the water quality is aging.

2.For the fading, be sure to find the source, the common is the sunken wood, the sunken wood that has not been treated into the tank, it will cause the water to turn yellow, although there is no harm, but it will affect the viewing.

3.If it is a problem with the feed, it is necessary to pay attention to replacement.

4.The aging of water quality indicates that the water is not changed frequently, and the situation of yellow water will appear.

1. Water temperature is a good cause, if the water temperature is too low, it will make the high regret fish "no spirit" so the body color is getting lighter and lighter;

2. Light is also a reason, the light is too strong, or too weak, and the general light is too weak to make the fish body color change and the wheel is shallow;

3. For fish breeding, it is best to use some colorful feed to make the fish look beautiful.

If the color of tropical fish becomes lighter, it may be caused by long-term indoor rearing, too long exposure to strong light, too high water temperature, feeding inferior fish food, long-term feeding of a single fish food, and too clear water quality.

I believe that many friends who raise tropical fish should have encountered the situation that the color of tropical fish has become lighter, so why has the color of tropical fish become lighter. In fact, this may be caused by long-term indoor breeding of fish that do not receive light, or because they are exposed to strong light for too long.

Moreover, when raising tropical fish, tropical fish will easily get sick and their lifespan will be reduced when they are at low temperatures. However, if the water temperature is too high, tropical fish will secrete a lot of mucus, which will also cause the body color to become lighter and lighter.

It may also be due to the fact that the fish are fed inferior fish food, long-term feeding of a single fish food, the water quality is particularly clear, and there is too much hydrogen and nitrogen and sulfide in the water, which will cause the fish to become lighter.

It may be that the light is too strong and the time is too long, causing algae to grow in the water. If that's the case, just change the location, or change the water more often.

Is it sunlight that can hit the fish tank, buy a few nitrifying bacteria balls, and nitrifying bacteria liquid to see if the situation can be better.

Feed too much,,, the fish feed can't be eaten, dissolve, and there is too much fish food, and there is a lot of excretion. The cause of the yellowing of the water. Generally, it is enough to eat once a day, and it is advisable to eat it in 5 minutes.

Because fish live in water. Don't change it often when the water is yellow, it will tire the fish to death.

1. I don't know if you have used finished fish food, inferior granular fish food will be decolorized, and water will have color when it reaches a certain concentration. Strengthen filtration, cotton rings, and proper feeding, and it should get better in a few days!

Whether there is sunken wood in the tank, some sunken wood will be discolored, but it will not affect the water quality.

2. The water in the fish tank is stagnant! The water is yellow because the water has deteriorated! Put activated carbon and change water to solve the problem.

Sunken bait.

The fulvic acid in liquid fertilizer will cause yellow water.
