Generally, this situation is easy to happen in the upper filter fish tank.
The filtering effect of the upper filtering fish tank is worse than that of the bottom filtering fish tank.
The reason is that the filter box of the upper filter fish tank has a small capacity and can't hold too much filter material.
Generally, it can be considered to put bottom sand into it to allow fish manure, residual bait and small floating objects to precipitate.
This will make the water clear easily.
There is also a new fish tank, which will happen if the nitrification system is not fully established.
There will be a short period of turbidity when the fish tank is first changed.
What should I do if the fish tank fogs? Hello, the general fish tank feels foggy. There are two kinds of suspects.
First, if there is something wrong with the filtration system, the filter cotton should be replaced or added.
Second, the nitrification system is not perfect, so it is best to inject digestive bacteria.
Finally, in this period, it is urgent to change water frequently, one third at a time.
1, increase the frequency of water change.
2. Strengthen the filtration system.
3. Adjust the feeding mode to reduce turbidity.
What about the foggy water in the fish tank? The solution is to change a lot of water.
The solution to the problem is to find the cause of smog and solve it fundamentally.
What happened after the fog in the fish tank changed water? The water turbidity caused by excessive particulate impurities in the water tank is called physical turbidity.
Generally, when changing water, fish tank sediment is washed up, and a large number of foreign bodies such as particulate impurities and short fibers will cause water turbidity.
However, this turbidity is not terrible, and most impurities can be filtered out or precipitated by filtering for several hours.
Then the fish tank naturally became clear again.
The fish tank is foggy. koi fish is lying on the low fish tank, and one of them is dead. What's going on here? First, environmental requirements. Koi fish has a strong adaptability to the environment, but it can't resist the sharp change of water temperature. When the temperature suddenly drops or rises by 2-3 degrees Celsius, it is easy to get sick. If the temperature fluctuates by 7-8 degrees Celsius, the fish will crawl under the water and can't eat. If the temperature changes sharply, koi fish will even die immediately. The optimum water temperature in koi fish is 20-25 degrees Celsius. At this water temperature, koi fish is active in swimming, with a strong appetite, strong physique and bright colors. Koi fish is suitable for living in a slightly alkaline and low hardness water environment, and spring water is the best. Contains a variety of mineral elements and other ingredients, which can increase the pigment of fish and make the body color of koi fish more vivid.
Second, farming technology. Koi fish's reproductive age is generally 3-8 years old, and her weight is above1.5kg. Fish with plump and round appearance, round head, long body length, no deformity, bright color, uniform color, symmetrical shape, no damage and no disease are selected as parents. From the appearance, the female fish has a short and plump body, an enlarged abdomen and a round pectoral fin. The male fish has a slender body and a slightly pointed pectoral fin. There are several white "idols" on the first fin and gill cover of pectoral fin. The breeding period of koi fish is similar to that of common carp. Generally, in April-May of each year, when the water temperature is stable above 16 degrees Celsius, the female and male koi fish can be picked out and put into the prepared pool according to the ratio of 1: 2, and the disinfected fish nests can be put into the pool in advance for them to lay eggs by themselves. After observing their spawning, the parent fish are caught and the fish nest is left in the pool to hatch.
Third, feeding management. In courtyards and hotels, ponds can be built for decorative purposes. The depth of the pond should be 0.6-0.8m, and the density can be slightly higher. 3-5 koi fish can be stocked per square meter. The pond is equipped with water spraying facilities or circulating micro-water, which is usually fed twice a day. A special brightening material for raising ornamental fish can be fed to brighten and form a perfect body shape. The daily feeding amount is 2% of the fish's weight? /FONT & gt； 10%, eat it in 20-30 minutes.
What is the foggy (white foggy) water quality in the fish tank? A large number of suspended solids are produced, and the treatment capacity of the filtration system is weak.
There are many reasons for the production of suspended solids, which are generally related to excessive food residues and feces. It is also related to the secretion of fish body surface.
What is the glass fog on the surface of the fish tank? That means there are oil stains and impurities.
Pour water on the surface with a spoon,
Just replace it,
It's simple,
Some people go to the oil film machine,
But I don't think it works.
What is the reason for the fog turbidity in the fish tank? The reasons and solutions are as follows:
First, the reason for the turbidity of fish tank water
The turbidity of fish tank water is not terrible. As long as the causes are found and dealt with in time, the safe and healthy growth of small fish can be guaranteed. There are several main reasons for the turbidity of fish tank water. You can observe and understand the situation in the fish tank and your daily operation steps, and find out the reason for the turbidity of the fish tank water. So what is the reason for the turbidity of fish tank water?
1. There are too many particulate impurities in the fish tank.
Generally, in the initial stage of cylinder opening, due to the use of new filter materials, a large number of foreign bodies such as particulate impurities and short fibers fall off, which will cause water turbidity.
There are too many microbes in the bathtub.
With the production of residual bait, fish manure and other organic substances, heterotrophic bacteria will immediately reproduce and decompose these organic substances, and the reproduction of heterotrophic bacteria will lead to the decline of water clarity and the formation of biological turbidity.
3. The sunlight exposure time is too long.
In the case of long-term illumination, plankton in the water will multiply faster due to enhanced illumination and rising water temperature, and the metabolism will produce certain sediments, so the viscosity of water will increase, the transparency will decrease, and the color of water will deepen, because all kinds of plankton will show different colors.
4. Improper addition of chemicals
The turbidity caused by the addition of chemicals, such as the use of water purifiers and flocculants, is rare and can be completely controlled artificially, and is not the main reason for the turbidity of fish tank water.
5. The air pressure in the fish tank becomes lower.
Sometimes the air pressure in the fish tank becomes lower, which will also be the turbidity at the water's edge. The phenomenon of water turbidity in Huangmei season will be more serious.
Second, the solution to the turbidity of fish tank water
Turbidity of fish tank water can easily lead to fish death. If found, it should be solved in time to avoid irreparable consequences. In fact, as long as we find out the reasons for the turbidity of fish tank water and then carry out corresponding solutions, the problem of turbidity of fish tank water can be easily alleviated. What are the solutions to the turbidity of fish tank water?
1. The new fish tank should be filtered frequently, and most impurities can be filtered out in a few days. Before filtering, it is best not to raise fish in this fish tank. After filtering, the fish can be put in. You can also add a filter to repeatedly filter the water in the fish tank in a short time.
2. Insist on changing the water every day (it is not necessary to change all of it, just use a device or use a hose to change a part) and replenish clean water that has been cold for more than 12 hours. This is done every day, and the pumping capacity can be changed more or less according to the water quality.
3. Keep the fish tank away from the sun and light it with a fish lamp.
4. Eliminate algae, control the honey juice of fish and reduce the number of fish appropriately. If the honey juice of fish is too big and the bait is too much, it will aggravate the pollution.
5. Raising more aquatic plants is also a good helper to purify the water body, turning the whole aquarium into a small ecological paradise, and the water body naturally becomes very clear.
6. By putting the sweeper and the moss-eating shrimp in the tank, we can remove the dirt and algae attached to the tank wall.
7. Use better fish feed. Some fish feed contains a large number of trace elements, which will breed a large number of microorganisms under long-term sunlight, affecting the water quality and thus affecting the health of fish.
8. Deal with the excrement discharged by fish in time to reduce the reproduction of heterotrophic bacteria caused by fish excrement residue. So the filter mentioned above plays a great role here.
9. Ultraviolet germicidal lamp +EM bacteria tablets can be used together. It is very effective to use ultraviolet germicidal lamp to control microbial overgrowth in water. Generally, it can kill all kinds of microorganisms in water within 1-2 days, with little damage to nitrification system. After ultraviolet sterilization, adding EM bacteria can make probiotics form dominant flora.
Why is the foggy water in the fish tank still yellow? When the water in the fish tank becomes Huang Shi, alum can be added to make it clear. Alum belongs to clean water. Adding 750 mg of alum to 1 liter of salt has the function of purifying water and sterilizing. Different alum content in turbid river water will affect the clarity of water. Alum water purification is a method often used by the people in the past. Its principle is that alum can ionize two kinds of metal ions in water: (Aluminum contained in alum is harmful to human body. Drinking alum purified water for a long time may lead to Alzheimer's disease. Alum is no longer advocated as a water purifier. Al ~ (3+) is easily hydrolyzed to form colloidal aluminum hydroxide Al(OH)3: Aluminum hydroxide colloid has strong adsorption capacity, which can adsorb suspended impurities in water and form precipitation to clarify water. So alum is a good water purifier.
