be put in tap water for 12 hours? No fish can be put in tap water for 12 hours. Tap water contains residual chlorine, so it can not be used directly to raise fish, it must be treated, this process is called trapped water. The commonly used method of trapped water is the drying method, which connects the water and puts it in the sun for at least one day to ensure the dissipation of chlorine. If the temperature is not very high, the drying time will be longer, and it will take at least a week to stand.
1, drying: drying is the most commonly used method of trapping water, through light to accelerate the volatilization of chlorine. It usually takes one day to dry in summer, about two days in spring and autumn, and three days in winter. Drying can not only remove chlorine, but also precipitate impurities in water, thus reducing the overall hardness.
2. Oxygen explosion: If you want to be trapped in the water quickly, it is too late to rely on drying, and it will take at least one day or so. However, oxygen explosion can shorten the time of being trapped in the water. If the amount of water is not much, it only takes 1-2 hours to remove chlorine, and it can also increase the oxygen content in the water body, which is also helpful for the breathing of fish.
3. Dosage: Although the time of oxygen explosion is shorter than that of drying, the amount of treatment is relatively small. In view of the situation of changing a large amount of water, chlorine remover is still needed. For example, Yulebao is one of them, which can effectively remove chlorine, so that water can be used to raise fish immediately.
