fish to recover from lying down after changing the water. It needs to rest for a period of time. During this period, do not feed and change the water to keep the water temperature constant. Usually this situation is caused by changing water too frequently or changing too much water, so the daily water change must control the cycle, but also pay attention to the amount of water. Of course, the water can not be changed for a long time, otherwise the water quality will deteriorate, the ammonia nitrogen content will increase, and the fish will be poisoned.
for the fish tank 1. Trapped water in advance: Tap water is usually used to change the water for the fish tank. This kind of water itself is not polluted, but after disinfection, there will be a small amount of chlorine residue, which is harmful to the health of the fish. Therefore, it is necessary to trap water in advance. After the water is filled, put it in a sunny place to dry for a few days. To get the chlorine out of the water.
2. Water pumping and water injection: Water shall be pumped from the tank before water injection. Pump can be used to pump water, if not, you need to find a pipe, use the siphon method to pump out the water at the bottom of the tank, so that the dirty things in the water can also be discharged. Then the new water can be slowly added from the wall of the tank, the process should be slow, do not change too fast, so as not to stimulate the fish.
3. Pay attention to the water temperature: In order to avoid the fluctuation of the water temperature, which will stimulate the fish, the temperature of the old water and the new water must be consistent, and the difference should not exceed 1 ℃. You can measure the temperature of the old water before changing the water, and then mix the new water according to this temperature.
