What is the best water for fish farming What kind of water is the best for raising fish

1) tap water: tap water is the domestic water used in our daily life, it is convenient and easy to obtain, it has undergone certain technical treatment, it is the best breeding water for freshwater ornamental fish. Tap water is a disinfected water source, and the water contains too many chloride ions to be used directly for fish farming.

Generally, the cooling method is adopted, and the tap water is placed in an open-air ventilated place, with the help of air circulation and sunlight, the residual chlorine in the water is volatilized, and the amount of dissolved oxygen in the water is increased at the same time. The cooling time is more than 24 hours in summer, more than 48 hours in spring and autumn, and longer in winter. In addition, chemical treatment can also be used, that is, baking soda (sodium thiosulfate) is used to neutralize the chlorine in the water, generally 2-3 grams per cubic meter of water or 5-6 grains in 10 liters of water.

When baking soda is used in excess or in hot weather, the water quality often deteriorates white, so special attention should be taken.

2) Well water: Well water belongs to groundwater, the water quality is hard, and the water temperature is constant. Well water needs to be exposed to the sun for more than 12 hours before use, so that the water temperature is balanced with the surface water temperature, and at the same time increase the amount of dissolved oxygen in the water.

3) River water: natural water, soft but turbid. Before use, the sediment should be purified or filtered in a reservoir before use. The river water contains many natural baits that can make the color of aquarium fish more natural and bright.

ps: The couple uses tap water that has been placed for a few days, but it doesn't bask in the sun (too troublesome), and it doesn't seem to be a problem......

It is best to raise fish with these 3 common waters, and the faster you live, try it.

Fish farming with tap water is fine. But tap water cannot be put into use directly. Before using tap water, the water needs to be treated in a series of ways.

1. Chlorine removal: There is still some chlorine in tap water, which has an adverse effect on the growth of fish. Therefore, before using tap water, it is necessary to let the tap water stand or expose to the sun for 1 2 days to remove chlorine.

2. Disinfection: Direct sunlight can effectively disinfect. You can also put a little salt into the water, which can also play a role in sterilization and disinfection.

3. Nitrifying bacteria system culture: fish will produce a lot of feces. Feces can be converted into toxic substances that affect their health.

Therefore, before raising them, it is necessary to cultivate a nitrifying bacteria system in water. That is, nitrifying bacteria are added to the water. This nitrifying bacterium is able to effectively dispose of manure.

4. Clean water quality: Fish farming also needs to ensure that the water is clean. Therefore, it is necessary to pay attention to changing the water when breeding, and it is best to install a filter in the tank.

5. Oxygen: Fish need oxygen to grow. Therefore, the water in which they are kept needs to have a certain oxygen content.

In addition, the pH and hardness of the water should be adjusted appropriately according to the habits of the fish being raised. The best water is the right one for them.

2. Can fish farming be cooled and boiled?

Fish can be raised with cool boiled water. Cool boiled water is more suitable for raising some fish who don't like hard water. Because the hardness of cool boiled water is relatively low.

However, there is a disadvantage of using cold boiled water to raise fish, that is, the oxygen content of the boiled water is very low. Therefore, if you want to raise fish in cool boiled water, it is best to first use an oxygen pump to inject a sufficient amount of oxygen into the water.

seeds, which cannot be used directly to raise fish. Generally, the cooling method is adopted, and the tap water is placed in an open-air ventilated place, with the help of.

After the water source, the water contains too many chloride ions.
