Is it necessary to . The main purpose of trapped water is to filter out chlorine in water and improve water quality. In most cases, household fish farming uses tap water, which is sterilized and contains a lot of chlorine, which can be removed from the water. Fish farming in rural areas partly uses well water, which can raise the temperature of well water and increase the oxygen in water.
? 1. Drying method: Put the water for fish farming in a place with light to dry. In summer, it is best to dry for more than 24 hours. In spring and autumn, it is best to dry for more than 48 hours. In winter, the light time is relatively weak. It is best to dry for more than 72 hours. When drying, you can use basins and buckets, pour tap water into them, ventilate and dry them.
2. Aeration method: Use a powerful oxygen pump to feed water for 24 hours without interruption. The aeration method can force out the residual chemical substances in the water.
3. Drug method: It can be used when there is no trapped water condition. The main purpose of trapped water is to filter out the chlorine in the water. Put Yulebao in the water to remove the chlorine that does not harm the health of goldfish.
4. Warm water: The chlorine in the water will volatilize when the temperature is high. You can use the water heater to heat the water first. The water temperature does not need to be too high. You can cool the warm water. The oxygen content of Liangbaikai is relatively low, so it should be used to raise goldfish after oxygenation.
