Do I need to change the water every other day to raise goldfish? How often to change the water for g

Change it once a week or once every half a month!

1. Time to change the water: The first thing to pay attention to when changing the water for goldfish is the weather, and it is best to choose a sunny day to change the water. The best time to change the water is 7 o'clock in the morning just after the sun rises, or after one o'clock in the afternoon.

Do not change the water and catch fish when the sun is scorching at noon, especially for the old green water, it is not advisable to change the water at noon, otherwise it will cause internal injuries and illness of the fish.

In addition, the appetite of goldfish will be reduced after changing the water, so after changing the water, you should reduce feeding or stop feeding for half a day, otherwise there will be too many fish and insects, which will cause fishy changes in water quality, causing goldfish to get sick or even die.

2. Water use: When changing the water, new (excellent) water must be used, and the water temperature difference should not be too large. If tap water is used, it must be dried for one day before use, or baking soda must be added to each square meter of water to neutralize chloride ions in the water.

If well water is used, it is better to use shallow well water to raise goldfish, but it is also necessary to dry it for a few days before use. If you use river, river and lake water, it must be unpolluted and can be used directly to raise goldfish, but the humus and parasites in the water are easy to harm goldfish, so it is safer to use after filtration.

3. Water exchange: The water capacity in the fish tank (pool) should be determined according to the influence of the climate of the four seasons on water quality. In spring, early summer and late autumn, it should not be too deep.

In order to avoid exposure to the scorching sun in hot dog days, the amount of water can be appropriately increased to make the water color appear tender green and prevent scalding tail disease. In winter, the temperature is low, so in order to prevent the bottom from freezing, the amount of water should be larger, and the water color can be green.

Fourth, the method of water change: when changing the water and injecting new water, it should be slowly mixed along the wall of the tank (pool) according to the amount, and it should not be poured or rushed, let alone flushed into the fish body, otherwise it is easy to make the goldfish catch a cold and internal injury, causing diseases such as fried scale disease and capillary congestion.

5. When changing the water, it is not advisable to use nets to catch valuable pearl scales, blisters, etc.

This is the right way to change the water for goldfish!

Generally, goldfish are raised for 2 or 3 days, and the water is changed once every 3 days, which is determined according to the number of goldfish. When changing the water, you can't change all the water, you need to expose the new water to the sun for about a day to remove the chlorine. If the water becomes cloudy again within two days of the water change, a second water change is required to keep the water clear.

Raising goldfish should change the water at least once every 2 or 3 days, but it is necessary to decide the number and frequency of water changes according to the number of goldfish in the tank and the excrement.

When changing the water, you should not change the water in the fish tank completely, otherwise it will cause the fish to be uncomfortable. The large amounts of chlorine and other microorganisms in the new water are harmful to goldfish, and the water needs to be exposed to the sun for a day or so.

It is not ruled out that the water was changed the day before yesterday, due to too much residual food in the goldfish tank, or due to too much food, the goldfish could not finish the tank. As a result, the water becomes turbid again, and it is necessary to change the water again to keep the water clear.

The water for raising goldfish at home looks clean, but you need to change the water at least once every 3 days or so. When the goldfish spits bubbles at high frequency in the water, it means that there is a lack of oxygen and the water needs to be changed in time. The new water must be exposed to the sun for about a day, and in the process of changing the water, the old water cannot be replaced completely, and the temperature difference cannot be higher than 4 degrees.

Although the water in the tank is very clean, the water in the goldfish kept at home is very clean, but the water should be changed regularly, usually at least once every 3 days. Keeping goldfish in winter can reduce the frequency of water changes.

However, when the goldfish floats in the water and frequently spits bubbles, it means that there is a serious lack of oxygen in the water, and the water needs to be changed in time. The new water must also be exposed to the sun for about a day, or in the shade for about 3 days, before the water can be changed.

When changing the water, do not directly replace all the water, and the temperature difference of the new water should not be higher than 4 degrees. In addition, when feeding the feed, it is necessary to feed a small amount many times, otherwise the goldfish will be easily strangled to death, and they cannot be fed at night.
