? The time for oxygen pump to remove chlorine is not fixed, usually 1-2 hours, but if the amount of water is relatively large, it may also take about 24 hours. The reason for dechlorination is that the water usually used for fish farming is tap water. After disinfection by the waterworks, there will be residual chlorine. Although the content is very low, it is not harmful to the human body, but it is still risky to the fish, so it is necessary to dechlorinate the trapped water. If river water is used, there is no need to remove chlorine.
of removing chlorine from fish tank water? 1. Drying: The most direct way to remove chlorine is drying. After connecting the water, put it in a sunny place to dry. In summer, the temperature is relatively high, so chlorine can be released in one day. In spring and autumn, it takes about two days, and in winter, it takes longer. Therefore, before preparing to change the water, it is better to dry the water in advance.
2. Aeration: Aeration is to pump oxygen into the water. This method can also remove chlorine, and it is more efficient and takes less time than drying. Moreover, aeration can not only dissipate chlorine, but also improve the dissolved oxygen in the water body, which is also helpful for the breathing of fish, but it needs an oxygen pump to do so.
3. Drugs: Drug dechlorination is a variety of dechlorination agents. For example, the common Yulebao is a kind of dechlorination agent. It can be used in emergencies, but attention should be paid to the dosage to avoid excessive phytotoxicity. Chlorine remover is usually used in aquarium shops, because there are many fish, drying and aeration are too troublesome, so it is necessary to use drugs to remove chlorine.
