Salt in tap water can not directly raise fish. Tap water contains residual chlorine, which can not be removed by adding salt, and salty water is not good for fish, especially freshwater fish. Usually, if you want to treat tap water, you need to dry it for a period of time so that the chlorine will volatilize. In the daily feeding process, only when the fish is sick, it is necessary to add salt to the water, and the concentration can not exceed five thousandths.
from fish in tap water? 1. Drying: The most common way to remove chlorine from tap water is drying. Drying time is generally related to the season, such as one day in summer, but it takes about two days in spring and autumn, and more than three days in winter. If the time is too short, chlorine will remain.
2. Aeration: If you want to remove chlorine quickly, the drying method is not feasible, because it takes at least one day, and the aeration can complete the chlorine removal in a few hours. The method of aeration is also very simple. Put the air head of the oxygen pump directly into the basin filled with water, and determine the aeration time according to the water capacity.
3. Medication: The methods of drying and aeration are often used in family fish farming, but if it is an aquarium shop, the water is changed more at ordinary times, and the above two methods can not meet the water demand, so it is necessary to use drugs to remove chlorine, but attention should be paid to the dosage, excessive dosage will cause certain harm.
