How to fishy fish?
No matter what causes the fishy smell in the fish tank, if it often stinks, it is best to treat it thoroughly as long as conditions permit. Temporarily transfer the fish to other fish tanks or containers, empty the fish tanks, then soak the dirty fish tanks with disinfectant and clean them again. Generally, there are white vinegar, edible or disinfectant alcohol, potassium permanganate solution, bleaching powder and 84 disinfectant. Can be used, can not only sterilize, but also deodorize. Note: after soaking and cleaning with disinfectant, it must be thoroughly washed off with water. After cleaning, put the fish tank in the hot sun for a few days. If there is no disinfectant or you are afraid that it will do harm to pet fish and cannot be disinfected with disinfectant, you can clean the fish tank with clean water and irradiate it with ultraviolet light for disinfection, and then expose it to the sun for several days. If you can't be exposed to the hot sun in rainy days, you can turn on the hair dryer to the highest heat, blow it repeatedly in the fish tank for about an hour, and then let it stand for a few days. Necessities and ornaments such as bottom sand and landscape stones in the bathtub also need to be disinfected to remove the fishy smell. After this treatment, the frequency of odor can often be reduced, and even if it is smelly, the fishy smell can be reduced.
Most fish tanks stink because the water quality is getting worse. Just change the water Fish feces, food residues, dead branches and leaves of aquatic plants and other wastes will rot and breed bacteria in the fish tank for a long time, which will cause the fish tank to stink. Therefore, it is necessary to clean up all kinds of residues regularly, and change the water in time when the water quality becomes turbid. Some fish farmers put filters on fish tanks and think it is unnecessary to change water. This view is wrong. Although filtration can maintain water quality for a long time, the function of the filtration system may be weakened, or the installed filtration system itself is very poor. In this case, filtration only delays the deterioration of the water body, and the water body will eventually deteriorate. Therefore, even if there is filtration, water should be changed regularly to prevent odor. In addition, the filtration system should be checked regularly, and the filtration material should be replaced in time after the filtration capacity drops rapidly.
Dead fish is also a reason why fish tanks stink. After pet fish's death, it will rot soon, spawning a large number of bacteria, which will make the fish tank stink, so it is necessary to fish out the dead fish at the first time to prevent it from stinking. As for the fishy smell caused by not fishing out the dead fish in time, this fishy smell is very heavy and stubborn, and it is difficult to wash it thoroughly with ordinary water and detergent. It can be thoroughly treated by the method mentioned at the beginning.
Fish eggs generally have a special fishy smell. Fish eggs that lose the ability to develop F will soon rot. Once they stay in the fish tank for too long, the water will give off a special fishy smell. When fish lay eggs, if they don't need to breed fry, they should be picked up and treated immediately. If they want to breed fry, they should also take them out and put them in special breeding containers for breeding, so as to avoid the dead eggs causing the water body to stink. If the dead eggs have caused the fish tank to stink, immediately salvage the dead eggs, clean the fish tank and change the water, which can solve the fishy smell problem.
After the fish is injured, if the wound is inflamed and rotted, it will often cause the water body to stink. Therefore, once the fish's wound is found to be large, it must be actively treated to prevent inflammation. For inflamed fish, anti-inflammatory treatment should be carried out at the same time, and water should be changed frequently to reduce the foul smell; For severely inflamed fish, it is best to discard them. Such fish will affect the water quality too much. No matter how you change the water, it will soon stink. If they can't bear to give up, they will be kept in a separate fish tank.
Long-term lack of dissolved oxygen in water can also cause fish tanks to stink. Lack of dissolved oxygen will lead to fish anorexia, food residues will increase, especially the odor of fish feces, and hypoxia will also lead to the death of aquatic plants and aerobic bacteria. Long-term hypoxia is often caused by high culture density. This situation cannot be solved by changing water. The fundamental solution is to reduce the culture density or use machines to increase oxygen. From the point of view of fish health, I suggest starting with a reasonable culture density.
Long-term poor air circulation will lead to long-term lack of dissolved oxygen in water. In addition, in the long-term rainy and stuffy weather, due to the drastic change of air pressure, the dissolved oxygen in the water will also be insufficient for a long time. In both cases, it will also lead to hypoxia and stench. First, change the water to remove fishy smell, and then configure an oxygen pump to supply oxygen to the fish tank to prevent odor.
There is something wrong with the water used for fish farming, and there are too many microorganisms, which will lead to the rapid deterioration of the water quality of fish tanks and give off a strong fishy smell. Many families are supplied with water by water companies, and the poor quality of water supply by water companies is well known. Even the supplied water has a strong fishy smell as soon as it is released. If fish are raised with such water, a little less water will stink. If you really have no choice, you can disinfect the tap water yourself. If the fish tank is small and needs less water, boil the water and let it cool for a day or two. Before changing the water, use an air pump to inflate the water for one hour. For large fish tanks, disinfect tap water with disinfectant, or irradiate tap water with strong ultraviolet rays, let the treated tap water stand for a few days, and then replace the fish tank.
Most fish have fishy smell, but the smell is different. Some people have a keen sense of smell. The extraordinary sense of smell will make these fish farmers feel that the fishy smell in the fish tank is very serious no matter what measures they take. In fact, the fishy smell they smell is the body odor of the fish itself, which cannot be completely removed. For people with extraordinary sense of smell, it is not recommended to raise fish or keep a distance from them. Many people with extraordinary sense of smell will unconsciously toss themselves as innocent as fish. This situation can compare the feelings of family members and people around them about fish tanks. If others can't feel the fishy smell, it can be judged that they may have an extraordinary sense of smell.
