Why is the water surface of the fish tank always dirty, and how to solve the problem of the fish tan

If it is a sleeve cylinder, it is equipped with a filtration system.

In my humble opinion:1You can take a look at your filter cotton. The filter cotton equipped with the sleeve is generally low-density cotton, and the material is not very good. If this is the case, then it is recommended that you change to high-density filter cotton, which is generally about a dollar.

2.Whether the filter has not been changed for too long to filter effectively.

3.This situation can also occur if you feed too much at one time, and it is better to eat within 1-2 minutes of each feeding.

Go to the fish shop to buy a pump and add oxygen dual-purpose plus an external filter nest is a set, 24-hour filtration oxygen, add a few drops of water purification agent fifteen minutes clear as a mirror, in the next is also to raise arowana, do not try.

There is no good way, either take it out when you change the water yourself, or stop feeding the insects and feed the fish and shrimp instead.

Possible Causes:

1. There are too many fish. The number of suitable fish is calculated in this way, and the fish tank raises 1 cm long fish per liter of water; In other words, the total length of fish raised in a tank of 100 liters of water is about 100 cm. If there is circulating filtration, it can be appropriately more.

2. The filter pump is too small. The filtration capacity of the filter pump, i.e. the filtration flow rate, should be 6 to 8 times the water capacity of the fish tank. That is, for a 100-litre fish tank, the flow rate of the filter pump should be 600 to 800 litres per hour.

If you are raising large fish, the flow can be appropriately larger, and the overall consideration is that the current does not affect the normal swimming of the fish under the premise that the larger is better.

3. Feeding too much. For ornamental purposes, the feeding frequency is controlled to 1 to 2 times a day, and the amount of each feeding is controlled so that the fish can eat within 5 minutes.

4. The filtered flora is not established. If the filter cotton has a faint silt smell, if not, the microbiota has not been established, you can consider adding nitrifying bacteria to the water to help the microbiota build up as soon as possible. Every time you clean the filter cotton, you can't clean it too clean, and you can't use boiling water to scald it; When replacing the filter cotton, it is best to keep part of the old cotton to preserve the culture.

The above is for reference!

The simplest thing is to add an anti-gas lift or a wave pump to grow the flora.

Add a filter to the fish tank and change the filter cotton frequently

The main reason is that there are too many harmful substances in the water, such as some fungi, and the main factor that produces harmful bacteria is caused by the deterioration of fish feces and leftover food.

There are three reasons why the water is turbid.

1. Physical turbidity.

It is mainly caused by the physical turbidity of water quality caused by small particles of impurities in the tank. The cause of physical turbidity may be the detachment of new filter media in the filtration system.

Solution: As long as it is filtered out again, or diligently, the water is changed regularly, and the feeding is rationed regularly, how much better it will be.

2. Chemical turbidity.

When chemical drugs are added to the water quality or fish disease, the drugs put into the fish tank are not disposed of in the later stage, and the feed with chemical elements is soaked in the fish tank for a long time, so that the chemicals in the feed react and dissolve in the water, causing turbidity in the water quality.

Solution: Use activated carbon adsorption. However, it is not recommended to use used activated charcoal a second time.

3. Biological turbidity.

The water quality is turbid due to the proliferation of microorganisms in the fish tank water, and the water quality may be turbid due to the overgrowth of organisms such as small green balls and chlorella. The water can be unhealthy in color, cloudy, whitish and gray, giving it a foggy look.

Solution: Use ultraviolet germicidal lamp + EM bacteria. It also reduces the conditions required for the growth of these microorganisms, such as light. The use of EM bacteria is to enhance the nitrification system and quickly decompose toxic substances such as ammonia.

Reasons why the water in fish farming gets dirty very quickly:

1. Physical turbidity: The turbidity of the water body caused by too many particulate impurities in the cylinder is called physical turbidity. Generally, due to the use of new filter media at the beginning of the cylinder opening, a large number of particulate impurities and foreign substances such as short fibers will cause turbidity in the water body.

However, this kind of turbidity is not terrible, and most of the impurities can be filtered out through a few days of filtration, so physical turbidity is not the main cause of turbidity in the fish tank water.

2. Chemical turbidity: turbidity caused by the addition of chemicals, such as water turbidity caused by the use of water purification agent and flocculant, this turbidity is rare, and it can be controlled artificially, and it is not the main reason for the turbidity of fish tank water.

3. Biological turbidity: The phenomenon of water turbidity caused by the proliferation of microorganisms is called biological turbidity. The water in the fish tank is chaotic, grayish-white and gives people a hazy feeling, these appearances are the characteristics of biological turbidity, and we often say that the water is turbid, which refers to biological turbidity.

1. Fish feed problems:

If you are feeding fish feed to the fish, then it is possible that the fish cannot finish eating because of the amount of greasy taste, and they sink to the bottom of the tank, polluting the water in the tank, causing the water to become turbid. If you feed the fish with feed, don't feed too much each time, so that the fish can eat in 5 minutes.

2. The problem of changing the water source for fish farming:

When changing the water, be sure to use new (excellent) water, the water temperature difference should not be too large, if you use tap water, you must cool it for 1 2 days before use, or add 2 3 grams of baking soda per cubic meter of water to neutralize chloride ions in the water. If well water is used, it is better to raise goldfish with shallow well water, but it must be used again for 1 2 days before use. If you use river, river and lake water, it must be unpolluted and can be used directly to raise goldfish, but the humus and parasites in the water are easy to harm goldfish, so it is safer to use after filtration.

3. Problems with the way of fish farming and water exchange:

The water in the fish tank should be changed in the evening.

At four or five o'clock, use a latex straw to gently suck off the feces and remaining feed and other dirt and part of the old water at the bottom of the tank, mix it with isothermal new water, when injecting new water, it should be injected slowly along the cylinder wall according to the amount, and do not fall and rush, let alone rush to the fish body, otherwise it is easy to make the goldfish catch a cold and internal injury, causing diseases such as rotten scale disease and capillary congestion. After the fish acclimatize to the environment, they will be transferred to normal feeding management.

If you feed too much food, you should take out the food that you can't eat in time, and the fish feces should be cleaned up in time.

It is recommended to pump out some water in 3 to 4 days, and then add new water, which can extend the water change time.

Food residues, feces, will become some nutrients under the action of light, and regenerate algae (burst algae) when the temperature and light are suitable. There are also these nutrients that make the water's edge sticky.

Two major pollutions:

Food scraps + goldfish droppings.

Think about whether you are feeding too much? Goldfish, in particular, are particularly edible.

Residues and feces are cleaned out in time (aquarium filters or straws), and then there is the problem of feeding density, and there is no harm in having more water and less fish. The best environment for fish farming is to create a simple ecological cycle.

People have a metabolism

Animals also have metabolism that is not just the fish poop you see, but the renewal of us humans

They have a layer of slime-like objects on their surface

You feel it when you catch a fish)

It's similar to humans, and it's also related to the metabolism of fish, and the stuff in the water is probably because of the metabolism of fish.

This is normal, fish farming should change the water frequently, and the weather is hot (when the temperature is above 26 degrees) every day to change one-tenth; Now it changes every two or three days, and every seven to ten days in winter. The water must be sun-drenched, and tap water cannot be used directly. When changing the water, it should be gently mixed in along the basin and the edge of the tank, and the fish should not be flushed, otherwise it will cause fried scales or illness.

Suck out their stool frequently with a small straw. The water will stay clean.

There are too many fish. Feed less, do not change the water every day, the fish will not adapt, the key is to pay attention to the establishment of a water self-cleaning system, the sales system is very important.

Koi carp, goldfish are relatively large excretion, fish feces and fish urine has a great impact on water quality, so fish farming needs to have a set of night filtration system.

Leftover food scraps, food grease, and little garbage floating up in the air. It is recommended to enter a minimum waterfall filter with degreasing membrane function, and it can be turned on for one hour a day to solve the water surface garbage.

You buy an oil removal membrane, connect the filter bucket to the water pipe and put it in the fish tank, you don't need to buy a waterfall filter.

The oil film bar is removed with a filtration system.

How can the surface of the water be dirty? Generally, the bottom of the tank is dirty.

It's time to change the water and fertilizer.

The water quality is not good, and the filtration is strengthened, and the nitrifying bacteria are cultivated.

Because you didn't take a bath and slept with the fish

Because the fish has diarrhea. Hey.

The problem reported by the landlord is expected to be caused by too much feeding.

The direct reason is that the biochemical system of filtration cannot decompose a large amount of waste in time, forming ammonium and other harmful substances in the water. This is an extremely dangerous sign and should be strengthened to change the water and reduce the amount of feeding.

The phenomenon that you reflected, "when the weather is not cold, this phenomenon does not occur, and after the weather is cold, the water in the fish tank will be muddy for three or four days" should be because of the sudden change in the weather, the amount of fish food is reduced, but the amount of food you feed is not reduced, and the nitrifying bacteria are affected by the sudden change in temperature, and the work efficiency is reduced, and the food residues and feces cannot be decomposed.

My fish tank uses an automatic feeder, and the sudden drop in temperature two days ago was similar, so there was no problem adjusting the amount of feed.

Your situation is the opposite of others.

The water is too dirty, and the mucus secreted by the fish is abnormal.

1. There are several reasons for foaming in water:

1. The density of the fish is large, the amount of bait is large, and the scale glue on the fish body is also shed, and the excretion is caused by more after feeding. The bubble is smaller.

2. Dead fish or live bait have died in large quantities (left in corners or dark places without being found), and have begun to seriously rot and stink, and there is already a smell of rotting corpses in the water. The bubbles are relatively large, but they are both large and small.

3. Feeding fishmeal bait products, caused by the water viscosity increased due to the water quality polluted by the bait spreading or the excessive use of coagulants such as gelatin and carboxymethyl cellulose in the bait; It is also possible that the pellet feed is not eaten by the fish and spoils, causing water pollution. The foam is large, with a few large bubbles.

4. Feed a large number of Daphnia, especially large Daphnia, which are caused by the decomposition of some Daphnia after death. The foam is small and medium-sized vesicles.

5. Acute death of earthworms (caused by bacteria). The water is extremely turbid, and the foam is generally small, so it should be removed or cleaned in time.

6. Oily food causes high water surface tension and poor permeability.

7. If you do not pay attention during the breeding period, some of the eggs discharged by the broodstock will be eaten by the fish, and the other part will be left in the corner or flow into the filter tank, which will become moldy and rotten for a long time.

2. Daily management matters:

1. Enhance water filtration and clean the filter cotton regularly;

2. Replace those inferior baits that are easy to disperse or have more foam after bait;

3. Always check whether there are goldfish eating leftover bait, and remove it in time;

4. Replace part of the new water regularly to maintain the freshness of the water body;

5. Temporarily turn off the filter for 15 minutes when feeding frozen Daphnia or red blood insects to avoid spoilage caused by flowing into the filter tank.

1. Excessive feeding causes excessive protein in water.

2. If the water has not been changed for a long time, fish feces and fish urine make the water quality thicker.

3. Relying too close to the light source, the water body is eutrophicated, which leads to the growth of algae.

Solution: 1. Reduce the amount of feeding and change the water appropriately.

2. It is recommended to change the water, about 40%, and the fish will not be able to stand it and will die easily.

3. The bubbles on the water surface are caused by the respiration of algae on the water surface, which needs to be removed, otherwise it will lead to a lack of oxygen in the fish.

Precautions: 1. Don't fish more than one tank small. Raise 1 cm fish with 1 liter of filtered water (length, width and height 10 10 cm), and it will be very easy to get sick and die if there are more.

2. Pay attention when releasing fish.

Over the water) should be put into the tank with the bag, after 15 to 30 minutes, go to the water and the bag, the naked fish into the tank, during which the water in the tank is added to the bag several times to make the fish adapt, and the first day is not fed.

3. The water change should be determined by your water quality.

If there is filtration and the tank is large or less, there is no filtration and the tank is small or more, the water should be dried, and the water should be washed with clean water (do not use detergent) when changing the water.

Replace one-sixth each time.

Bubbles in the fish tank? Whether it is caused by these 4 reasons is also very simple.

Potassium permanganate is used for bai, not for clean water, your zhi jar asks.

The problem is that there is no dao, water mixing is your filtration problem, that is, it is incomplete filtration, your filtered water is not completely into the filter tank, or what is oxygenated, the garbage is broken and then flushed back into the water, the filtration is generally multi-layered, biochemical cotton and glass rings are very important, you add nitrifying bacteria, but nitrifying bacteria must be with the help of solids' Residence', in order to reproduce and play a role, so your water mixing has a lot to do with the instability of the nitrification system, no need to put other drugs, you change one-third of the water, add nitrifying bacteria, add on the filter cotton and glass ring, but I have to know what you filter how big the tank, and nitrifying bacteria must turn off the light when adding, because bacteria are afraid of light exposure at this time, the stability and moderation of water temperature is also the key to reproducing digestive bacteria, generally around 28 degrees nitrifying bacteria will be very active, which is very helpful to fish and water, potassium permanganate does not need to be put more, generally powdered or potioned, diluted with water to light pink on the line, but I suggest not to do this, because it is useless, water mixing is not a problem with the tank, even if the tank is dirty, potassium permanganate will not be used, note: potassium permanganate is a disinfection effect, not decontamination, not for clean water.
