The frequency of changing water for goldfish in summer is usually twice a week, and each time, 30% to 50% of the water volume in the fish tank should be replaced. In summer, due to the relatively high temperature, the water quality is likely to deteriorate. Therefore, it is necessary to change the water more frequently to keep the water clean. The specific methods of changing water and precautions are as follows:
Frequency of Changing Water:
It is recommended to change the water twice a week in summer, and replace 30% to 50% of the water volume each time.
Methods of Changing Water:
General Water Change:
Gently suck out 1/10 to 1/5 of the dirt at the bottom of the fish tank along with the old water every day using a rubber tube. Remove the dust on the water surface and the floating feces, and gradually pour in new water at the same temperature along the wall of the water tank.
Partial Water Change:
In the hot summer and early autumn, when the water quality turns green but has not deteriorated severely, you can swirl the water in the tank in a spiral shape. After letting it stand for a while, use a rubber tube to suck out 1/3 to 1/2 of the old water and pour in an equal amount of new water.
Thorough Water Change:
This is usually carried out when turning over the tank, selecting juvenile fish or adult fish, and is suitable for situations where the water quality has severely deteriorated, the moss is too long, or there are too many fish. After thoroughly cleaning, pour in new water at the same temperature. Let it stand until the water temperature is equal, and then transfer the fish back to the original tank.
Precautions:
Water Temperature Difference:
The temperature of the new water when changing the water should be close to the water temperature in the fish tank. Generally, the temperature difference should be controlled within 1°C. In winter, the water can be heated to an appropriate temperature in advance.
Chlorine Removal:
Tap water contains chlorine, which can harm the gills of goldfish. Before changing the water, the tap water can be left standing for 24 hours, or a professional chlorine remover can be used.
Gradual Replacement:
Avoid changing all the water in the tank at once. It is safer to change 1/4 to 1/3 of the water volume each time. This can improve the water quality without disrupting the ecosystem in the fish tank.
Cleaning Debris:
When changing the water, you can use a siphon tool to clean the fish feces, bait residues, etc. at the bottom of the fish tank. However, do not over-clean to avoid damaging the microbial ecosystem.
By following the above methods and precautions, you can effectively keep goldfish healthy and the water clean in summer.
