The method of turning water into alkaline is relatively simple, just put a certain amount of coral sand in the water. Coral sand contains many trace elements, including a large number of calcium and magnesium compounds, but the main components are calcium carbonate and calcium hydroxide. Although these two substances are relatively stable and insoluble in water, there is still a small amount of water dissolved in water, which produces a small amount of negative ions in the environment of water immersion, which improves the ph value of water.
The long-term slow change of these methods is that the time period of pH is longer, but the influence on fish growth will be less.
Method 2:
Adding sodium bicarbonate to water, also known as baking soda, can improve the alkalinity of water quality after dissolving in water. Generally, after baking soda is stirred, the water-insoluble part is filtered out, and the aqueous solution is poured into the water tank. It should be noted here that every time the baking soda water is added, it needs to be strictly measured. Don't be greedy and add it in small quantities for many times.
The advantage of chemical reagent method is that it can be adjusted quickly, which will change the PH value of water quickly, but the amount is difficult to control. It is necessary to monitor the change of PH value range of water, and the calculation of fish tank water quantity is determined according to the PH value of chemical reagents for detecting water quality.
Extended data:
In rural areas, people who raise fish are more common, but those who raise fish with soda water are less common. On the Pamirs, in Heiziwei Township, Wuqia County, Xinjiang, Ainiwal Yaordas is raising fish with soda water.
Ainiwal Yaerdas Fish Farm is located in the characteristic breeding base of Wuqia County, covering an area of 6.5438+0.8 million square meters, and was aided by Changzhou, Jiangsu Province, with an investment of 4.57 million yuan, 2065.438+0. 1. The Gobi desert, which used to be a piece, is now covered with pieces of clear water and fences. Fish are playing in the water, and all kinds of birds are flapping their wings to chase.
"After testing, the plateau spring water in our county contains a variety of trace elements and a large number of water-containing complex ion groups, and all of them are pure natural aerated soda water. The fry grew up in such water. How can the taste of meat be unique and delicious? As for the reason why the fish is not long, it is mainly affected by the high altitude, and the growth cycle is slightly longer than that of the plain. " Technician Yue's explanation dispelled his doubts.
Ainiwal Yaordas also uses favorable resources to develop characteristic poultry breeding. Looking around, flocks of wild ducks, red-billed geese and geese swim on the water, and the current scale has reached 60,000. Ainiwal Yaordasi said: "These characteristic birds feed on insects and grass seeds in aquatic plants around fish ponds, and we also feed corn and other feeds. Birds play in the water, and the excrement discharged becomes the best food for fish. "
"Now, the fish in our fish pond has reached 16 tons, which is expected to be listed next year. In 20 13 years, my income reached 38,000 yuan. " Ainiwal Jardat's face showed a bright smile. He said that under the planning of the county, the characteristic breeding base will soon develop plateau fishing tourism and will certainly attract more tourists. He should seize this opportunity and do something big.
Experts from Zhou Ke Fisheries Department said: Raising fish with weak alkaline soda water reduces the acidity of fish, which is more conducive to changing the sub-health state of modern people, such as general fatigue and decreased immunity.
