What is the best water for fish farming What water should be used for fish farming?

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.

Tap water. Freshly released tap water is the most ideal water for fish farming. However, it should be noted that the water temperature is often quite different from the water temperature in the fish pond (tank), and the temperature adjustment treatment is required (in some areas, the tap water contains more chlorine gas also needs to be dechlorinated).

Goldfish eat a lot of food, consume a lot of oxygen and excrete a lot of waste, which pollutes the water and breeds germs. In order to keep the water clean, a filter should be installed and a tenth of the old water should be replaced every day while removing excrement and bait from the bottom of the tank.

Fish farming to use tap water, but can not be directly connected to tap water, need to be connected to tap water a day in advance, net value overnight before use, if there is enough time, you can put the water in the sun to dry.

1. River water.

You can go to the surrounding creek and fetch water. You can't go to small rivers polluted by industry, it's better to go to rivers with better water quality.

2. Well water. In the cities, well water is more difficult to find, but there are many wells in the suburbs and rural areas. The water quality of the well is generally good and suitable for fish survival.

3. The water quality is clear, not thin or fat.

The water quality is clear and there are fewer suspended particles. The water should not be too thin (like pure water) and should not be too fat (there will be oil films, foam, algae blooms, etc.).

4. The smell is normal.

Odorless, or with a hint of fishy smell. If there is a fishy odor, there is definitely a problem with the water quality.

5. The water color is normal.

Water color is determined by the species and quantity of plankton (algae). Good water color should be a light brown, yellow-green, and oily green, while bad water should appear gray-white, gray-yellow, and black-brown. If the water in the fish tank is as colorless and transparent as pure water, it means that the water is too thin and the bacteria in the water are too small, which is not the good water we want.

A very important basic skill of fish farming is to raise water, and water cultivation is to raise bacteria, not only to raise nitrifying bacteria, but also to raise other microorganisms that are conducive to maintaining water quality.

6. If you feed tropical fish by yourself, it is not enough to use river water and well water, because the water temperature required by tropical fish is higher, so you need to put a thermostat in the tropical fish pool.

Non-toxic is the most basic condition for good water for fish farming, but it is also the most critical indicator. The toxin index is the decisive indicator to determine the quality of water quality, and it is the first place.

Water is the most important part of fish survival. Many friends say that our water quality is very good and we can drink it directly Some say that this fish lives in the wild and can live in any kind of water in my house In this case, why do so many friends' fish keep dying In fact, the water looks simple, but in fact, there are many secrets in it, and the quality of the fish depends on its balance.

Fish farming in tap water is the choice of many friends, not to choose, but to choose. We know that tap water does have fewer bacteria or something, but the amount of drugs in tap water is just off the charts for fish! Chlorine in tap water is the biggest killer of fish, but chlorine is relatively easy to remove.

After sun exposure and oxygen explosion, chlorine in tap water can be quickly removed.

But tap water is not only chlorine, such as impurities and other substances in the tap water at home, I can't say anything specifically, but it is very dirty, not what you can imagine.

I believe that friends who have water purification equipment at home know how dirty tap water is. However, after simple treatment such as self-settling and oxygen blasting, it is still possible to add it to the aquarium. However, there is a huge difference in water quality between the north and the south, which also leads to the difference between the breeding species in the north and the south.

In order to regulate and control water quality, on the one hand, it is necessary to understand the biological, chemical and physical processes that occur in aquaculture waters, enrich the subject knowledge of material migration and transformation in water bodies, and the general test points of water quality objectives; On the other hand, the regulation of water quality has important theoretical significance. Mastering water quality is key to ensuring the proper development of a wide range of fish.

Therefore, good water quality must be maintained, and this is the principle that the proverb "to raise a pond of fish is to first manage a pond of water". If we want to control the pool water well, we should first understand the water quality. The so-called water quality, in simple terms, is the quality of the water body.

It has different requirements depending on the aquatic plant.

Can't you keep fish on tap water? How do you remove chlorine from water? What is a nitrification system? Small secretary fish logbook 3 ftWater Farming Arowana Fish Farming Basics Water Quality.

It is better to raise fish in water that has been dried in the sun, because some substances in the water just from the tap can cause the death of the fish, so it is better to put the water in the sun to dry.

What kind of water is suitable for fish farming? Rural koi fish breeders share dry goods, there are two kinds of water don't use.

Tap water is sufficient, but the tap water from the tap needs to be exposed to the sun to decompose the chlorine in the tap water, and the exposed water will make the fish live more freely and not easily get sick.

You can go to the natural clear river to receive water, the water is pure natural, the oxygen and trace elements in it are very suitable for fish survival, it is very easy to raise, and the fish is not easy to die.

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.
