What to do if the fish tank water is yellow, the solution to the yellowing of the fish tank water

The water has not been changed for too long, and algae grows on the walls of the tank.

The first reason is that the water in the fish tank has not been changed for too long, and it slowly boils into old water, so some microorganisms and plankton in it grow in large numbers. Because these microorganisms and plankton are not transparent, they also have some colors, although they are very small, but when there are many of them, they live in the water body. Even though we can't see it with the naked eye, when they reach a certain size, it looks like the water starts to have some color.

The second reason is that when there is a lot of algae growing in the fish tank, it will also make the water quality of the fish tank look a little yellow. In fact, in this case, it is not that the water in the fish tank is really colored, but through the glass fish tank, some brown algae grow on the wall of the fish tank, so we look at the visual effect that the water quality is a little yellow.

<> Ornamental Fish Turbidity in the water quality of ornamental fish is a common problem, and there are many reasons why the water becomes turbid. Before finding out the cause, you also need to save the turbid water quality, so I have compiled six methods for you to refer to.

1. Put enzymes into the water, and the water for fish farming becomes turbid, which is often due to the increase in organic matter in the water, and the enzyme can quickly decompose the organic matter in the water.

2. UV sterilization method is adopted. As mentioned before, if the fish body is attached to the cilia multiplication, it will cause the water of fish to become eroded, at this time, in addition to the usual diligent water change, with the aquarium special ultraviolet sterilization lamp sterilization is a good choice.

3. Built-in strong filter brocade in the filter of the aquarium, such as ultra-fine porous foam, wool wool, wood toner powder (bag), etc., which can quickly adsorb organic matter in water.

4. If the water for fish farming becomes turbid, and at the same time you feel that the water is seriously foul-smelling, you can use ozone (O3) to pump gas, oxidize biogas, eliminate the odor and sterilize, and make the water quality clear.

5. Use the EM group to decompose the organic matter in the water, and convert the organic matter into nutrients for aquatic weeds to be absorbed by aquatic weeds.

6. The most direct method is to be diligent in changing the water, the water for fish farming becomes turbid, and it is a good choice to change the water frequently.

The most ideal water quality for fish farming is yellowish and translucent, if it is yellow and turbid, it means that the water quality is not good, according to the situation you said, it should be filtered not strong enough, how big is the tank? How many fish are raised? What is the wattage of the filter? What are the filter materials?

If the breeding density is too large, the water pollution will be fast, change a larger filter, choose a large filter box, put more filter materials, filter cotton, biochemical cotton, ceramic rings, bacterial houses, etc. are more commonly used filter materials, which not only help the cultivation of nitrifying bacteria, but also filter out goldfish feces and residual food.

The filter cotton should be cleaned regularly, once a week or so, and replaced once every 3 months.

To see if the feed is faded, you can add a few grains to the glass and soak for a while to see if the water is stained.

The solution to the yellowing of the fish tank water

1. Scavenger.

Algae removal: If it is brown algae.

The outbreak causes the water in the tank to turn yellow, then you can put a scavenger in the tank to remove these algae.

Clear it out. If the inner walls of the fish tank are yellow, you need to clean the fish tank and replace the water.

2. Cook sunken wood with water: If you use sunken wood and other substances as decorations in the fish tank, you can boil it with water before putting it in, so as to avoid the phenomenon of yellowing of water.

3. Regular water change: In order to avoid yellowing of water, it is necessary to change the water regularly. Especially in the summer, when the temperature is relatively high, the water needs to be changed more frequently.

4. Clean up the drug or change the feed: if it is caused by the drug, then the residue of the drug needs to be removed after the fish disease**. If it is caused by feed, it can be replaced with other types of feed.

The reason why the fish tank water is yellow

In the process of fish farming, there is a possibility that the water in the fish tank will turn yellow, and the first thing to understand is the reason. Specifically, the following situations are common:

1. Brown algae outbreak: If the yellowing of the water is very obvious, and even the inner wall of the fish tank is yellow, then it may be caused by the brown algae outbreak.

2. Caused by sunken wood: Some farmers will put some sunken wood into the fish tank as decorations in the process of fish farming, but these decorations may cause the water to turn yellow.

3. No water change for a long time: In the process of fish farming, regular water change is an important step. If the water is not changed for a long time, the water will be filled with old water, and the water will also turn yellow.

4. Caused by drugs: When fish are sick, some drugs need to be used, which may cause yellowing of water, such as yellow powder and nitrofuracillin.

Wait a minute. In addition, it is also possible that it is caused by some feed.

1. Put activated carbon

Activated charcoal can adsorb pigments and drugs. Whether it's feed fading or drug-induced yellowing, activated charcoal can help you. Wash the activated charcoal, and then put it under the white cotton, depending on the degree of yellowing of the fish tank water, it usually needs to be placed for 3 7 days.

Once the yellow color has faded, the activated charcoal can be removed.

2. Change the feed

The feed that is usually fed to the fish is also one of the causes of the yellowing of the water. If it is caused by feed, you can consider changing the feed. In fact, sometimes you can feed the fish some tender vegetables, chop the points and throw them into the tank, the fish like this snack very much.

3. Change the water

If the water is not changed for a long time, the water quality will be too old and will cause yellow water, and the easiest way is to change the water. Generally speaking, the time to change the water is: once a week in spring and autumn, once every three or four days in summer, and once every half a month in winter.

Also be careful that the fish tank is not exposed to direct sunlight or that the water will also turn yellow.

Instructions for the treatment of yellow water in fish tanks

Regularly replace the fish tank with 1 3-2 3 dried new water, and pay attention to keeping the temperature of the new water consistent with the temperature of the water in the tank. The essence of this method is to drain the old yellow water and dilute it with new water. It can be said to be the cheapest way to solve the yellowing of the water body of the fish tank.

Now there are a lot of products for fish tank yellow water, such as activated carbon, magnetic treasure, protein cotton, etc., the essence of which is adsorption. Adsorption is not decomposition, similar to magnet adsorbing crushed iron filings, this product can absorb the pigment of water in a short time and store it inside the product.

It should be noted that since this kind of product is adsorption, it must have an adsorption saturation value, once saturated, if it is not replaced in time, it will regurgitate the pigment and re-pollute the fish tank.

Dyed feed, untreated sunken wood, brown algae, filtration that has not been cleaned for a long time, excessive feeding density, dyed filter cotton, etc., will cause yellow water in the fish tank. Treating the pigment at the source is the symptom and the root cause.

The solution to the yellowing of the fish tank water

1.Change the water. The filtration is strong enough that the brown algae will attach to the tank wall, and the light will shine, and the water body will turn yellow, and it is also possible that the water itself is indeed no problem, but the tank wall where the brown algae is attached will be yellow, so the fish tank water body as a whole looks a little yellow.

Algae can be removed and water can be changed to solve the yellow water, and the water can be changed more vigorously. Change the water to weaken the yellow. Change the water frequently until the water is clear and meets your expectations.

2.Increase the filtration volume.

In fact, the main function of increasing the filter material and increasing the filtration volume is to increase the living space of nitrifying bacteria, and the main task of decomposing yellow pigment falls on these industrious nitrifying bacteria, the more nitrifying bacteria, the more stable the water quality, and vice versa.

3.germicidal lamp.

The germicidal lamp is a very effective means of water purification and sterilization, but be careful not to face the filter material directly, otherwise the nitrifying bacteria will disappear together, and the gains outweigh the losses.

How to raise fish tank water:

Open the cylinder first install the water pump to circulate the whole cylinder of water, some friends are willing to add this water quality stabilizer, I personally do not recommend using it. We add the filter material, first of all, physical filtration, you can add a few sheets of white cotton, you can filter the impurities in the water.

The order in which the filter media is placed is that the water flow passes through the physical filter media first, and then through the biochemical filter media. Attention should also be paid to the placement of the water pump, and the water pump should be as far away from the outlet pipe as possible, which is conducive to the circulation of water in the fish tank. Just turning on the pump to circulate the water for a day is equivalent to trapping the water.

After cleaning and disinfection and equipping the equipment with filter media, we began to raise water. The purpose is to remove chlorine in tap water, remove impurities and reduce the number of harmful substances in the water, cultivate a large number of nitrifying bacteria, and then form a stable nitrification environment suitable for fish farming. This process of water cultivation will not be fast.

The solution to the yellowing of the fish tank water is as follows:1. Put activated carbon in the filter medium. Because the adsorption capacity of activated carbon is very strong, it has a miraculous effect on yellow water, especially the yellow water caused by sunken wood.

Generally, after the activated carbon is inserted, it can return to its original state in about 2-3 days.

2. Reduce feeding and change water frequently. This method is mainly aimed at the yellow water caused by eutrophication of water bodies. Because we usually feed too much, there are too many nutrients in the water.

Therefore, the most effective and direct way is to reduce the number of feedings, in fact, most of the fish we generally raise at home are adult fish, which no longer grow bodies. So it's okay to feed once a day, or even once every two days, and you don't need to feed that much.

3. Reduce the lighting time of the fish tank. Some fish have a habit of turning on the lights in the tank in the morning and then going to work or going out during the day without turning off the lights. When I got home, I didn't turn off the lights until I went to bed at 11-12 o'clock at night.

In fact, this fish tank is lit all day long, and there are still quite a lot of algae growing in it, including some microorganisms, which grow relatively fast. Therefore, the light time can be appropriately reduced, generally if the light of the fish tank of ordinary fish farming is about 5 hours.

01 Check first, whether the water quality in your fish tank has become turbid, then it means that you have changed the water for the fish too few times, to put it bluntly, you are too lazy, hurry up to change the water for the fish, and brush the fish tank seriously.

02 In addition, some people will find that they have just changed the water for a few days, but the water in the fish tank will turn yellow, then you can observe that there is not a lot of fish feces in the water, if more, it means that you feed too many times, reduce the number of feedings.

03 If the fish tank does not have a filtration system, then the water turns yellow and it is related to this, quickly buy a filtration system to install, if there is, then you have to see if the filtration system is faulty.

04 Another reason is more common, that is, too much fish food is put in, the fish can't finish eating, the fish food is floating in the water, so the water will also turn yellow, and every time the fish is fed, it is good to immediately fish out the remaining fish food.

The water in the fish tank is very yellow, which is caused by several different reasons, and can be treated accordingly according to different reasons:

1. It may be a sign of a brown algae bloom.

If the water yellow is more obvious, and the glass is also yellow, it may be that the algae exploded in the tank, although the brown algae is always eaten, but occasionally irritable, it is also a "yellow you are not negotiable" posture.

2. It may be that the feed drug fades.

All living things get sick and take medicine when they get sick. It's just that some eat on land, and some eat in water. Sometimes drugs fed to fish (e.g. yellow powder, nitrofuracilin, etc.) can cause the water to turn yellow; The leftover feed eaten by the fish will also turn yellow if soaked in water for a long time; Some reddening feed will also make the water yellow, in short, you must take into account the feeling of water after eating.

However, in this case, the disease does not cause much burden to the fish. As long as you feed some greens at ordinary times, chop them and throw them into the jar, after all, dietary fiber is not something that only people need.

3. It may be that the sinking wood causes the yellow water.

Many people like to configure sunken wood. This thing has a variety of forms, seemingly stretching wantonly, but one move and one style are implicitly in line with aesthetic standards. Sunken wood increases the force of the fish tank, but it also turns the water yellow.

In fact, Shen Mu was holding back a stomach of yellow water, and it would definitely not work to throw it in directly. Cook it before placing it, it is healthier and good for water quality.

4. It may be that the water has not been changed for a long time.

For fish, encountering a lazy owner can always make the fish desperate. If you don't feed in time, you may be able to lose a mermaid line, but if you don't change the water, you will definitely be able to get sick. If the water is not changed for a long time, the water quality will deteriorate, the water will turn yellow, and even the fish will get sick.

The solution is very simple, change the water frequently, and clean the filter cotton or filter material at the same time, and the frequency can be determined according to your actual situation.

5. It may be due to lighting.

If there is nothing wrong with the water quality, and the hard-working fish owner still can't find the reason for the yellow water, he can get a diving lamp, put it on the surface of the water, and the light shines underwater, which can also make the water look clearer.

6. It may be the reason for the filtration system.

The headache is the filtration system, basically all aquarists will worry about the problem of their own filtration system, because the filtration system is not good, the fish can not effectively filter the leftover food residues fish excretion, and the water will definitely turn yellow.

Generally, this situation occurs in fish tanks with filter tanks, fish tanks with filter barrels, and fish tanks with built-in filters. Solution: Increase the frequency of water changes and strengthen the physical filtration of the fish tank, such as adding a few more pieces of cotton.

However, if you want to **, it is best to replace the filter tank and put an extra magic carpet in the dry and wet separation box.

7. Water bodies may be improving.

If it is a new tank, or a new water ecosystem is being established, there will also be a phenomenon of water yellowing, at this time the state of the fish is normal, but the water quality is slightly yellow, and there is no need to worry about it, and there is no need to deliberately increase the frequency of water change, (according to the actual situation, once a week or half a month) only a quarter of the water can be changed each time.
