Why does the water in fish farming turn red in a few days?

The reason why the water quality of the fish tank turns red.

The first and most common case is that we are for some aquarium fish.

Reddening of the feed. If these reddening feeds are fed too much, and the ornamental fish in the fish tank are not eaten, then they will slowly turn the water in the fish tank red after soaking in the water for a long time. So in response to this situation, what we need to do is to control the amount of feed we feed at all times.

And it is best not to feed too much of these red-increasing feeds, or to feed the fish with other feeds, so that the nutrition is relatively balanced.

The second situation is to put some dyed decorations in the fish tank, or some inferior sunken wood, which will also cause the water quality of the fish tank to turn red. This kind of harm is more serious, because these dyed substances dissolve in the water of the fish tank, which is harmful to ornamental fish. Therefore, if this situation is discovered, these decorations, including some inferior sunken wood, must be taken away.

Then you can put some activated charcoal in the fish tank.

Or protein cotton to help quickly absorb these harmful substances.

In the third case, it may actually be the effect of lighting. Because there are some fish tanks with glass, it will also cause visual color aberration. It is possible that the water in the fish tank has turned yellow after a long time, and then because of these color differences, it will look like it has turned a little red, which is not much related, as long as the normal daily maintenance of the fish tank can be changed.

One is because of the excrement of the fish in the fish tank, the second is because of the decomposition of fish food fed every day, and the third is because of the oxidation of the fish water in the fish tank, so the fish water will change color after a few days.

Normal, aquatic causes. Oxygen filtration doesn't stop, it's good for a week.

Remember to put it in a ventilated and sunny place with a large mouth container for a week longer, which can shorten the time of the fish tank water mixing whitening.

The nitrification system was not fully established, or the nitrification system was broken due to the large proportion of water exchange. Place.

The specific nitrification system is actually to grow and produce enough nitrifying bacteria in the fish water, which can decompose the tiny garbage in the fish water, causing the precipitation to be pumped away by the filtration system, so that the fish water becomes clear and transparent, and the water cannot be changed constantly because the water is turbid, so that it is always a turbid state, and a nitrification system must be established.

The method is that the water does not move, and there is no way to turbidity, the temperature rises about 32 degrees, and the oxygen pump is used to remove the oxygen and filter it in the fish water, pour into the living nitrifying bacteria (sold in the fish market), and the bottom of the tank can be paved with some perforated stones as a breeding ground for nitrifying bacteria, so that the nitrification system will be established more quickly, and the nitrification system can be initially improved in about a week, and it can be completely established in about half a month, and at the same time, according to the habits of the self-rearing fish, some of the trapped new water can be replaced. If the filtration is good enough, the nitrification system is fully established, and the water will be extremely clear (but be careful not to destroy it again). No matter what kind of fish you raise, this is a necessary step in the early stage of water raising, as the saying goes, fish farming first raises water, and good water can raise good fish.

It must be that you put too much fish food, fish food is pigmented.

It's possible that you're raising too many fish, or you're feeding too much feed!

There are many fish raised, and there is no purification system.

The color of the small red fish raised at home is getting lighter and lighter, it may be because of the water quality, resulting in some microorganisms or fungi on its surface, making it lighter, or it may be that the water quality disinfectant purchased dilutes its color.

The water in which the goldfish are raised is red, indicating that the water quality is turbid, the air is thin, and now it needs to be replaced with clean water.

This is related to many factors, such as: feed, filtration, etc., some of the general water deterioration, it is recommended that you change the water once a week, each time to change one-third of the total water body.

Red water is one of the more common water quality in the process of aquaculture, and it is very easy to cause water quality deterioration if it is not treated for a long time, and the water body is seriously hypoxic, resulting in floating heads and even flooding ponds for breeding animals. The common red water is caused by the excessive source of dinoflagellates, which can also produce toxins that are toxic to aquatic animals such as fish and shrimp. Most of the reasons for the reddening of water quality are caused by too much dinoflagellates, in addition, the water body has a single nutrient, low dissolved oxygen in the water, high organic matter content, and acidic water quality can cause the water color to turn red.

According to the cause, red water can be divided into three types: red water caused by the overgrowth of dinoflagellates, red water caused by single algae phase in ponds, and red water caused by acute algae inversion in ponds. Dinoflagellates like to grow in water bodies with a lot of organic matter, high hardness and high pH value, and when dinoflagellates multiply, the water is reddish-brown and commonly known as "red water". When the red water in the culture pond is caused by dinoflagellates, the fish will not be in a serious floating state, and it is unlikely that the pond will be flooded.

However, the red water caused by dinoflagellates reflects that the pond has a single algae phase, low stability, and is prone to large-scale algae inversion.

Redness (yellow) is normal, this water is raised by the entire filtration circulation system, has good water activity, is very suitable for the growth of fish, the transparent water is in the super filtration, fasting, water purification agent, fungicide, anti-inflammatory drugs and so on under the effect of the effect, can only be cultivated in a short time.

The fish tank must be filtered frequently, and it only takes a few days to filter out most of the impurities inside. Before filtering out, you can't keep fish in the fish tank at this time, and only after filtering until the water quality is clear, can you put the fish in at this time. It is also possible to add a filter, so that the water from the fish tank can be filtered repeatedly in a short time.

To be precise, the water in your fish tank should be called: clear and translucent. Redness (yellow) is normal.

This water is raised by the entire filtration cycle. It has very good water activity and is very suitable for the growth of fish. The transparent water in the aquarium is the effect of super filtration, fasting, water purifiers, fungicides, anti-inflammatory drugs, etc.

It can only be farmed for a short period of time, and it is not suitable for family play.

Summary. Hello dear, <>

The red color of the water in fish farming is caused by a variety of reasons, the most common of which is algae blooms, which are a type of plant in the water that, when they bloom, can turn the water green or cloudy, and sometimes even red. This phenomenon is known as "red tide" and usually occurs during periods of high summer temperatures. Red tides can severely affect water quality and lead to fish kills.

Why does the water in which fish are raised turn red.

Hello dear, <>

There are a number of reasons why the water in fish farming turns red, the most common of which is the algae outbreak, a plant in the water that, when they dig and multiply, turns the water green or turbid, and sometimes even turns red. This phenomenon is known as "red tide" and usually occurs during periods of high summer temperatures. Red tides can severely affect water quality and lead to fish kills.

kiss, or caused by red bacteria. Some red bacteria can multiply in the water, and they will turn the water pants red. This phenomenon is known as "red water" and is often modeled after a situation where water is polluted or treated improperly.

Red water can pose a threat to the health of people and animals.

How to deal with it? Kiss, if it is caused by algae explosion, you can use drugs to treat the reed bark, such as copper oxide, copper oxide is one of the commonly used algaecide drugs, which can effectively control cyanobacteria and green algae in the water.

Summary. Hello dear, the fish tank has been raised for a few days, the blood color of the fish has turned dark red because of the water quality, the poor water quality will lead to the collapse of the nitrification system, and the ammonia nitrogen in the water will increase, threatening the normal survival of the fish. For aquarium fish, ammonia nitrogen is highly toxic, and if you put fish in water with too much ammonia nitrogen, compared to people in a space full of carbon monoxide, it is not difficult to understand that aquarium fish turn dark red.

In order to solve the symptoms caused by the deterioration of water quality, some disinfectant fish medicine can be placed on the basis of continuous oxygen + periodic water change. When the symptoms are almost gone, you can also add some antibiotics to strengthen your immunity, I hope it can help you <>

After a few days of keeping fish in the tank, the blood color of the fish turned dark red.

Hello dear, the fish tank has been raised for a few days, the blood color of the fish has become dark red because of the water quality, oh dear, the deterioration of the water quality will lead to the collapse of the nitrification system, and the ammonia nitrogen in the water will increase, threatening the normal survival of the fish. For aquarium fish, ammonia nitrogen is highly toxic, and if you put the fish in water with too much high levels of ammonia nitrogen, compared to people in a space full of carbon monoxide, it is not difficult to understand that aquarium fish turn dark red. In order to solve the symptoms caused by the deterioration of water quality, some disinfectant fish medicine can be placed on the basis of continuous oxygen + periodic water change.

When the symptoms are almost gone, you can also add some antibiotics to strengthen your immunity, I hope it can help you <>

What is the reason, every time I kill a fish, the blood is not bright red, it is dark red, and the customer looks unsatisfactory.

Pro, because the brigade and the fish have died or are dying, the oxygen in the blood has decreased, and because the hemoglobin in the blood cells is bright red when the oxygen content is high, and dark red when the oxygen content is low, so it is dark red.

Oh, that's going to put fish medicine.

Oh. Then my fish tank is going to sell some fish medicine and put it in.

Yes dear, buy some fish medicine.
