in the fish tank? If there is no place to trap water, you can use an oxygen pump to aerate the new water, which can also achieve the effect of dechlorination. If you feel that this way is still too troublesome, you can also add Yulebao to the tap water, which is very simple and fast. If you raise some more solid fish, you can use tap water directly, but you'd better pay attention to temperature control to avoid too large temperature difference between old water and new water, which will stimulate the fish.
? 1. Dechlorination: The primary purpose of trapped water is to remove chlorine. Tap water itself will not be polluted after being treated by waterworks, but the disinfection process will lead to residual chlorine, which may endanger the health of fish, so it is necessary to use drying, aeration and other means to volatilize the chlorine in the water.
2. Temperature rise: Trapped water can not only remove chlorine, but also raise the water temperature. Tap water is generally cool, and there is a certain temperature difference with the water in the fish tank. Trapped water can also raise its temperature, so that it is closer to the water in the fish tank, so that the fish will not feel uncomfortable after changing the water.
3. Oxygenation: If the water is trapped by aeration, it can not only volatilize chlorine, but also increase the oxygen content in the water. Fish live in the water, but also need to breathe, the level of dissolved oxygen in the water is particularly important for the breathing of fish, but also conducive to the maintenance of water quality.
