The water used for fish farming is usually tap water. This water contains residual chlorine. Although the content is not dangerous to humans, it is still very deadly to fish, so it must be removed. The purpose of trapping water is to remove chlorine, of course, the method of removing chlorine is not only trapping water, but also through the way of explosive oxygen to discharge chlorine, or with some chlorine removal drugs.
1. Airing: Airing trapping water is the most common method. Generally, 1-2 days before preparing to change the water, put the connected tap water under the sun to dry. It should be noted that if there is no sun, it is necessary to extend the drying time, when the temperature is low, it also needs to dry for a while, otherwise the chlorine volatilization is not clean.
2. Explosive oxygen: If you want to quickly remove chlorine, you can use an oxygen pump to supply explosive oxygen to the water. If there is not much water, it only takes about 1-2 hours to discharge the chlorine. However, there is a certain requirement for the power of the oxygen pump. It is worth mentioning that explosive oxygen can not only remove chlorine, but also improve the oxygen content of the water body, which is very helpful for the breathing of fish.
3. Medication: The efficiency of drug chlorine removal is the highest, but for novices, the dosage is not easy to control. Once the dosage exceeds the standard, it may cause certain harm, so there is still a certain risk.
