What is the correct way to change water for fry and what should we pay attention to?

Changing water for fry is different from changing water for adult fish, and water should not be changed too frequently, otherwise it will stimulate the fish. Usually once a week, the old water with fish fry should be poured into the new water, but not too fast, in order to avoid water quality fluctuations, resulting in the death of fish. In addition, after changing the water, if the size of the fish is different, it is better to separate the big fish from the small fish, otherwise the big fish will eat the small fish, causing unnecessary losses.

1. the correct way to change the water for the fry

Do not change the water for the fry too often, so as not to stimulate it.Usually, the old water filled with fish fry should be poured into the new water, the process must be slow, do not change the water violently, which will cause fluctuations in water quality and water temperature, which is harmful to the health of fish fry, and even cause their death.Usually change once a week, after changing the water to separate the big fish and small fish in time, so as not to eat the small ones.

2. what should we pay attention to when changing water

1. Trapped water in advance: Generally, tap water is used for raising fish at home. Although this kind of water does not have any pollution, it contains residual chlorine, which is harmful to the health of fish.Therefore, we must trap the water in advance and put the water in the sunshine for a day, so that the residual chlorine can dissipate and ensure the safety of the water body.

2. Pay attention to the water temperature: When changing the water, you must pay attention to the water temperature. The temperature change will stimulate the fish to a certain extent. Usually, the new water is 1 ℃ higher than the old water, but the temperature difference should not be too large. It is best to keep the temperature before and after changing the water, so that the fish can adapt to it more easily.

3. Proper cleaning: When changing the water, properly clean the fish tank, pump away the dirt at the bottom of the tank, and then add new water from the tank wall, so that the water quality will remain stable.If we do not pay attention to cleaning up, the more dirt accumulates, the more water will be polluted.
