Mineral water pisciculture need not trap water. Usually, only tap water is needed for fish farming, because tap water contains a small amount of chlorine, which can not be dissipated without water trapping, thus causing harm to the health of fish. There are many ways to trap water, such as drying, aerating the water, or preparing some chlorine remover to pour into the water, which also has a good effect.
of water trapping? 1. Drying method: The most commonly used method of water trapping is drying method. Put the water into a basin and put it in a sunny place to dry for a few days. Usually, the drying time is related to the season. In summer, when the temperature is high, it is enough to dry for one day. In spring and autumn, it is necessary to dry for two days. In winter, it is necessary to dry for about three days to ensure that the chlorine volatilizes cleanly.
2. Aeration method: In addition to drying method, aeration method is also a good choice, especially when waiting for water, the speed of aeration is much faster than drying, usually a few hours can be done. The gas head of the oxygen pump is introduced into the water, which can not only remove chlorine, but also improve the dissolved oxygen of the water body.
3. Chemical method: The chemical method is to use chlorine remover and other drugs to remove chlorine, which is more suitable for lazy people who are too troublesome. It is very convenient and fast. In addition, this method is usually used in aquarium stores, but according to the scale of feeding, the amount of chlorine remover should also be carefully studied, and too much will inevitably cause phytotoxicity.
