Why not raise koi?
There are some reasons why raising koi is not recommended: 1. Mixed breeding problem: If the fish in the mixed tank are too diverse to distinguish whether they are cold-water fish or tropical fish, or if the koi fish are mixed with aggressive fish or certain species of goldfish, the koi fish may be bullied or even injured. 2. " Illness Seeking Medicine ": Whenever the koi got sick, they would use medicine indiscriminately. For example, salt was used as an all-purpose fish medicine. Different diseases required different treatments. Indiscriminately using medicine could lead to health problems or even death. 3. ** Raising density **: If you don't pay attention to the breeding density, you will buy whatever you like. Raising fish in an ultra-high density requires extremely high cultivation techniques and equipment. Moreover, the survival pressure of the fish will increase, and it is not conducive to controlling the water quality. 4. [If you don't raise water, let the fish out.][If you don't have the habit of raising water, you can't wait to put the beloved carp into the tank and pool as soon as you buy it. This is a wrong practice.] 5. ** Overfeeding **: Because of his love for koi, he was afraid that the koi would not have enough to eat. When he saw a fish, he subconsciously wanted to feed it. However, the koi did not have a stomach and would not stop eating when they encountered food. If he fed too much food residue, it would pollute the water and even cause the koi to die. 6. ** Over-cleaning or not cleaning the filter material **: Good filtering is very important for koi fish breeding. The nitrating bacteria in the filter material is the biggest guarantee for the health of koi fish. Changing the filter material too frequently or cleaning the filter material too clean will destroy the nitrating system. However, if you are too lazy and do not change the water for a long time or do not maintain the filtering system, the water will be too high in the water and the koi fish will be prone to problems. 7. ** Water temperature sensitivity **: Although the koi can adapt to a wide range of water temperatures, it is very sensitive to water temperature fluctuations. A sudden change in water temperature of more than 5 ° C may cause the koi to die. 8. ** Easy to cross-infect **: Koi fish are very easy to cross-infect. Fish from different fish ponds have different microenvironments on the surface and in the body. If they are put into the tank without quarantine, 80% of them will cause cross-infection of bacteria and parasites between Koi fish. 9. ** Need to pay attention to water quality testing **: The water body of the tank koi is small, and it can only rely on some fixed filter tanks to start the nitration system. The water quality is easy to fluctuate. If you don't pay attention to water quality testing and don't change the water for a long time, it will lead to problems in water quality parameters such as pH, nitrogen, nitrogen, and nitrates. 10. ** May be affected by unexpected situations **: For example, if a long-term power failure occurs during intensive fish farming, the result may be catastrophic.

Going Home, Different Scenes Every Time Every time I go home, it is like opening a brand - new picture book filled with diverse and fascinating landscapes. On a sunny day, as I step onto the path leading home, the sun shines brightly, casting long and slanting shadows on the ground. The trees along the road seem to be bathed in a golden glow. Their leaves rustle gently in the breeze, as if whispering a warm welcome. The wildflowers on the roadside are in full bloom, their colors so vivid that they seem to be a patchwork of rainbows dropped by angels. Butterflies flit among the flowers, their delicate wings glistening in the sunlight. When it rains during my journey home, the world takes on a completely different look. The raindrops fall like silver threads from the sky, hitting the puddles on the ground and creating countless tiny ripples. The whole landscape seems to be shrouded in a thin layer of mist. The trees look a bit hazy, like ink - wash paintings. The sound of the rain hitting the leaves is like a natural symphony, playing a soothing melody. In the twilight, the sky is painted with hues of orange, pink, and purple. The birds are flying back to their nests. The houses in the distance look so warm and inviting, with a faint glow of light seeping through the windows. The fields are quiet, as if resting after a long day. Each time I go home, these different sceneries make me feel the beauty and magic of nature, and also make me cherish every journey back home even more. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Old Li wants to make jade
If Old Li wanted to make jade, the following were some aspects and basic steps that needed to be considered: ** 1. Initial preparations ** 1. ** Selection of Materials ** - He needed to choose a suitable jade material. It was necessary to carefully examine the nature of the jade, cracks, flaws, etc. For example, to check if there were more cracks in the jade, impurities, etc., and to observe from various angles, such as the front, back, side, top, etc., so that the quality of the jade could be clearly understood. 2. ** Design Planning ** - According to the characteristics of the jade material, he designed it. If the jade material had more cracks, it needed to be cleverly conceived, such as using the "borrow" technique, borrowing the cracks into patterns, digging dirty to cover the lock. You can draw a pencil draft first, and then draw the final draft after confirming the pattern. If it was a jade carving that needed a long time to be carved and might come into contact with water, it was best to use an oil-based pen that was not afraid of water, or cover it with waterproof shellac (but do not use both at the same time). ** 2. Production process ** 1. ** Casting ** - He used various jade carving tools to make the outline of the jade. There were many types of jade carving tools, with different shapes and size. After the blank was completed, it might be necessary to draw another draft to accurately shape the shape according to the actual situation. This was because when the carving went from the surface of the jade material to the inside or from the plane to the three-dimensional image, new problems might be discovered, such as the picture becoming wider, so the modification after the blank was very important. 2. ** Carving ** - In the process of carving, due to the high hardness of the jade material and the strong grinding power of the diamond powder grinding head, the grinding of the two would produce high temperatures and sparks, so water was essential. It had the function of cooling and wetting the medium. In the process of carving, it was necessary to constantly deal with problems such as cracks and flaws in the jade material, to retain the shape of the jade material and the original shell to the greatest extent, and to make the carved jade meet the expected functional requirements. For example, when playing with it, it should feel smooth and comfortable. At the same time, it should have fine workmanship and be worth looking at. If there was a hollow part, the firmness of the force surface should be considered. 3. ** Polishing ** - After the carving was basically completed, they entered the polishing process. Polishing was boring and monotonous, but it was very important, just like "dressing" a jade piece. The polishing process required great care. Even after polishing, there might still be uneven luster on the jade pieces, and there might be white spots on the surface of the jade pieces that were difficult to enter. 4. ** Sealing wax (wax)** - If the jade piece was used for display or sale, it needed to be further beautified after polishing, that is, sealing wax (wax) operation to improve the beauty of the jade piece. From the perspective of ancient jade production, there were still some traditional processes. For example, in ancient times, large wire saws might be used to pull the jade sand to cut the raw materials, and then the upper machine would use the large wheel to cut the large pieces. In the ancient jade cutting process, the jade would be cut into cubes or square strips with a "cutting" tool, the edges and corners of the cubes or square strips would be "punched" to be smooth, the surface of the jade would be ground with a "grinding" tool, and the inside of the jade would be hollowed out during the chamber cutting process. The drilling process was very important for the jade ware that needed to be carved with hollowed-out flowers, using tools such as bows and rods (with diamond inlaid at the bottom); for the hollowed-out patterns, using the "search bow" tool and using water-soaked stone sand to cut according to the drawn lines, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
