Everyone has an idea, that is, fish should be raised first and water should be released first. Water is the source of all things. If fish can't live without water, we can imagine the importance of water for ornamental fish. So, what is hydroponics? How to raise water?
First, what is water saving?
Simply put, hydroponics is a process of changing water (here, drinking water) unsuitable for fish (tropical ornamental fish) into water suitable for fish's life through a series of methods.
Second, why do you want to carry water?
The process of raising water is actually a process of environmental cultivation. Water suitable for human consumption is often not suitable for fish, and different kinds of fish have different adaptability to water quality, so it is necessary to cultivate water suitable for fish life according to their adaptability.
Third, pay attention to the temperature when raising water.
Since it is a tropical fish, we must ensure the necessary temperature. It is best to keep the water temperature of large tropical fish above 25 degrees all the year round, and try to avoid large changes in water temperature. If the water temperature changes too fast, it is easy to cause fish to catch a cold, which is a fatal disease for ornamental fish. In addition, white spot disease is mostly caused by the sudden drop of water temperature. The water temperature in my house is constant at 26 degrees Celsius all the year round, and the fish in my house have hardly had white spot disease. There is still a need for reliable high-quality thermostats.
Fourth, the pH of water.
All kinds of tropical fish have different habitats and prefer different water quality. Generally speaking, all kinds of ornamental fish in South America like acidic water quality, tropical fish in Africa like alkaline water quality, and tropical fish in Southeast Asia are suitable for neutral water quality. Some low-grade tropical fish have strong adaptability to water quality because of long-term artificial feeding, but many high-grade fish will be difficult to grow well or even die if the pH of the water used for feeding is inconsistent, and colorful immortals are typical. In addition, the humpback whale in large fish is strong and not afraid of mixing water, but it will die soon in alkaline water. Generally speaking, alkaline water fish and neutral water fish can survive and grow in weakly acidic water, while fish in acidic water can hardly survive in alkaline water. But this is not absolute.

Verb (abbreviation for verb) The softness and hardness of water.
The hardness of water depends on the content of calcium and magnesium ions in water. The water quality in the south is soft and the water quality in the north is hard, but they are basically within the tolerance range of tropical fish. In some areas, groundwater is used as water source, and the water quality is extremely hard, which is not suitable for raising tropical fish. South American fish like soft water, while African fish and semi-marine fish of the family Petanidae like hard water. The hardness of water has little effect on the growth of fish, but it has a close image on color and reproduction. If colorful immortals, various lampreys and Asian dragons have bright colors and can reproduce successfully, it is best to use soft water. Cultured lantern fish are colorful, and friends who have the conditions can try bottled pure water.
Six, the degree of raw and cooked water
Clean tap water is sanitary, but it is not suitable for raising ornamental fish immediately. Especially some delicate fish, it is difficult to survive in tap water. The reason is that the water is too raw. Tap water has no organic components, which is too irritating to fish skin. The long-term water quality of tropical fish dissolves some mucus secreted by tropical fish and is rich in nitrifying bacteria. This is called boiled water and old water, which is closest to the water quality of tropical fish in nature. Therefore, when raising some precious species of tropical fish (Asian dragon, colorful, arhat), if it is too late to sink in, some low-level fish should be broken in tap water first, as well as piranha, kiss fish, coffee and so on. Can act as a brave general who broke into the tank. Nitrifying bacteria should be added at the same time.
Seven, the cleanliness of water
All kinds of harmful bacteria multiply in polluted water. Even strong ornamental fish species will be invaded by harmful bacteria and suffer from diseases such as eye patch, rotten fin, rotten meat and water mold, and the polluted water is not suitable for ornamental tropical fish. If the water quality is clean, a good filtration system is the guarantee, which requires good physical filtration and biochemical filtration capacity rich in nitrifying bacteria. Also, for fish that are easy to cause water pollution, such as map fish, we must strictly control the number of cultured fish. Appropriate relaxation of feeding density is also a way to ensure good water quality.
There are criteria for judging the "good water" of fish farming. First of all, the water quality should be non-toxic, clear and transparent. The water with normal odor can be slightly water-like, rich in beneficial bacteria and dissolved oxygen, with appropriate temperature and qualified physical and chemical indicators such as hardness and pH.
