to open the jar to raise water, there is no need to add salt to open the jar to raise water. Usually, freshwater fish need to be salted only when they are sick. The habit of adding salt is not good, which makes it difficult to control the salinity of the water, so it is impossible to determine the amount of salt used after illness. If it is a marine fish, the breeding water should be artificially prepared seawater, which requires adding sea salt to the water.
1, trapped water: first of all, water should be trapped, because the water used is tap water, if this water is not treated, it will contain residual chlorine, thus causing certain harm to fish. The purpose of trapped water is to volatilize chlorine, and the method is to put it in a sunny place for a few days.
2. Bacteria cultivation: The second step of water cultivation is bacteria cultivation. There are not only fish in the fish tank, but also some beneficial bacteria, which can decompose the organic matter in the water and transform it to avoid poisoning the fish. Generally, nitrifying bacteria are cultured, and the raw materials need to be poured into the jar, and the lights need to be turned off to explode oxygen.
3. Oxygenation: The last thing we need to do is to increase oxygen, because the lack of oxygen in the water will be harmful to the breathing of fish, so we need to use oxygen pumps and other equipment to oxygenate the water for a period of time to improve the oxygen content and ensure the health of fish.
