1. What water to use for fish culture Tap water is usually used for fish culture. Compared with the water taken in the wild, tap water is cleaner, and the temperature is more suitable. Most importantly, it is very convenient. However, it also has a small disadvantage, that is, the water contains a small amount of chlorine, which is harmful to the health of fish. Therefore, chlorine should be volatilized by trapping water and other methods, so as to ensure that the water body will not cause harm to fish, and at the same time, the water temperature can be appropriately raised.
2. How to remove chlorine from tap water for fish culture1. Drying: Drying is the most common method to remove chlorine. After connecting the water, put it in a sunny place to bask in it. Usually, it takes one day in summer, two days in spring and autumn, and more than three days in winter. By drying, not only the chlorine gas in the water can be dissipated, but also the temperature of the water body can be raised.
2. Aeration: If you are in a hurry to use water, it is often too late to dry it. At this time, you can try aeration to remove chlorine. The so-called aeration is to pass the air head of the air pump into the water, and accelerate the volatilization speed of chlorine in the water by constantly filling gas, which usually takes only a few hours.
3. Drugs: In view of the large amount of water changed, for example, the water, drying and aeration in aquarium stores can not meet the demand, so only drugs can be used to remove chlorine at this time. There are many kinds of chlorine removal agents, no matter which one, we must control the dosage, otherwise it may produce certain phytotoxicity.
