is the correct way to add water to the fish tank for the first time? You can use a bailer to scoop water into the fish tank for the first time. It should be noted that the water must be trapped before it can be used, because it is tap water, which contains residual chlorine, if not trapped, it will cause harm to the health of fish. In addition, do not fill up the water, it is best to keep a certain distance to the top, if the water level is too high, it will lead to increased pressure at the bottom, increasing the risk of cylinder explosion.
in the fish tank 1. Air the water in advance: Before changing the water in the fish tank, you need to prepare the water. Because you use tap water, you need to air it. The purpose of doing so is to remove chlorine, so that the residual chlorine in the water can dissipate and avoid harm to the health of the fish. In addition to drying, chlorine can also be volatilized by aeration and other means.
2. Pump water and add water: The first step of changing water is to pump water. You can use a pump or prepare a pipe to pump water from the bottom by siphoning, which can also clean up the dirt at the bottom of the tank. Then water should be added to it, and the water should be exchanged from the wall of the tank. Do not change the water violently, which will cause the fluctuation of the water body.
3. Pay attention to the water temperature: In order to avoid the adverse effects of water temperature changes on fish, it is better to keep the water temperature consistent before and after the water change, and the maximum difference should not exceed 2 ℃. Usually, the water temperature in the tank is measured first, and then new water is added according to it.
