How often to change the water for a goldfish?
1. For goldfish, can change the water every 3-4 days, but the specific frequency of water change should be determined according to the actual situation of the breeder. If the number of goldfish raised in the fish tank is large, the frequency of water changes will be higher, and the water needs to be changed every 2-3 days. If the number of goldfish kept in the fish tank is normal or small, you can change the water every 7 days. If there is no filter system in the fish tank, it is best for the breeder to decide the frequency of water changes according to the water quality. Normally, it takes about 3 days to change the water. If there is a filter system in the fish tank, the frequency of water changes can be reduced, to about once every 10 days or so, if the water in the fish tank is not too turbid, you can also change the water about once every 15 days.
2. What kind of water do you use to raise goldfish? 1. Groundwater: You can choose groundwater for raising goldfish because groundwater contains a lot of minerals. Long-term use of groundwater to raise goldfish can make their bodies healthier. 2. Tap water: Tap water is more convenient and the first choice of many breeders, but using tap water to raise goldfish requires exposure to the sun first. Because tap water contains chlorine, although it is not harmful to the human body, it is very harmful to goldfish, so the breeder needs to be exposed to the sun for 1-2 days before using it. Goldfish can change the water 1-2 times a week. The frequency of changing the water depends on the density of feeding, the size of the fish tank, and whether there is a filter device. If the number of goldfish is large, the breeder needs to change the water every 2-3 days. If the number of goldfish is small, you can choose to change the water once a week. If a filter system is installed in the fish tank, the water can be changed every 10 days or so. If there is no filter system in the fish tank, the water is easy to be cloudy, and the frequency of water changes needs to be increased appropriately.
