How to quickly raise fish with water, how to raise fish with water

The so-called fish farming first refers to the preparation of water suitable for the survival of fish before the fish enter the home. If this is not mastered well, it is difficult to succeed in fish farming. There are several types of water in nature:

1) Rainwater: Rainwater has high oxygen content, but it is dissolved in it by harmful substances such as exhaust gas in the air, which is more harmful to the respiratory system of fish, so it is not possible to raise fish with rainwater. 2) River water, lake water:

The water is high in oxygen and contains plankton and microorganisms that fish like, which may seem ideal, but the water of rivers and lakes contains a lot of bacteria and parasites.

It is easy to make delicate pet fish sick, and such water must be purified before it can be used. 3) Well water, groundwater: These waters contain a lot of inorganic salts.

However, the oxygen content is low, and the temperature of the well water and groundwater is also low, so it must be dried in a container for 2 days, so that more air dissolves into the water, and the water temperature is normal before use. 4) Tap water: Tap water is disinfected and filtered, which is a more hygienic domestic water, but tap water contains chlorine used for sterilization.

Bleaching powder and other substances are not good for fish, there are two ways to remove chlorine, one is to dry, store the water in a bucket or basin for 2 days, let the chlorine be discharged, and the drying process also increases the capacity of oxygen in the water that the fish need; At the same time, the water temperature is also the same as the normal temperature: second, if there is no time to dry, only the chemical chlorination method is used to add one-ten-thousandth sodium thiosulfate to the water.

Stir and leave for one hour before use. There are all kinds of bacteria in the water, and they are interdependent and mutually restrictive, so that they form an environment for organisms to survive, just like there are various pathogenic bacteria and fungi in the air (such as the flu).

Germs), which is what you call bad bacteria, and there are also a large number of "good" bacteria that are beneficial to people, and some good bacteria can kill pathogenic bacteria to serve human health, but they are symbiotic and are all products of nature. It is impossible to separate, fungicides are often killed by bad bacteria and good bacteria, there is no way to only destroy bad bacteria and keep all the good bacteria, as long as you are still living on earth. You said that if all the bad bacteria died, would the good bacteria that fed on the bad bacteria live, and the good bacteria would not survive, would people in such an environment live?

The same is true in the water, don't think that there is any medicine that can cure and kill all the bad bacteria, but keep all the good bacteria so that the fish will never get sick, since you decide to raise fish, you can't be afraid of trouble. Anyone who has ever had experience in fish farming knows the truth that "when the water is clear, there are no fish". It's about the water being so clean that the fish can't survive.

The best way is to take care of them diligently, manage them more, raise the fish fat and strong, and enhance their resistance to diseases. Of course, this does not mean that there should be no fungicides, especially in aquariums, fish tanks, etc., due to the small water capacity, the fish eat and drink in it every day, and it is easy to make all kinds of bacteria multiply quickly, beyond the resistance of the fish, so bactericidal drugs are necessary. You can go to the fish market and pick it up, and a few years ago I saw a fish market that was labeled "nitrifying bacteria."

It is said that it can have an inhibitory effect on bacteria in the water, and you can consult the stall owners of those fish markets, and they will tell you what bactericidal drugs are better.

The correct methods of fish farming and water farming include drying, resting, and chemical treatment.

1. Bask in water

Tap water is dried in an open-air ventilated place for more than 24 hours in summer, more than 48 hours in spring and autumn, and more than 72 hours in winter.

Advantages: energy saving, environmental protection, good effect, but also increase the temperature of the water body. Disadvantages: The requirements for the site and equipment are high, you need to prepare in advance, it is not suitable for rainy days, it is not suitable for northern winter, and it is inevitable to fall into impurities during the drying process.

2. Let stand

There is no outdoor venue, and the water can be left indoors for 2 to 3 days.

Advantages: It is also possible to live in a building, and the time and space are relatively wide. Disadvantages: A large number of water storage containers need to be prepared. Housing prices are very high, and the cost of land occupation for urban residents is relatively high, and the living experience is declining.

When the water is trapped, the lid of the container must be open, and the time needs to be appropriately extended. In addition, the trapped water should not exceed three days, otherwise harmful bacteria and algae in the water will multiply, and the quality of the water will decline.

3. Air pump treatment

High-power oxygen pumps are used for 24-hour uninterrupted gas blasting to force out chemical residues in the water body. 50 liters of water, use a large air pump to aerrate the water, 1 2 hours later, ready to use. It is usually used in combination with the second method.

Advantages: safe, no sequelae, even if the large cylinder is turned over, it can be used. Disadvantages: Laborious, requires at least a 5W air pump.

Summary. First of all, put enough tap water in the fish tank and remove chlorine through a period of aeration.

First of all, put enough tap water in the fish tank and remove chlorine through a period of aeration.

Then put a small number of fish in it, and there are organisms in the water, so that microorganisms can reproduce and grow.

03 Water cultivation also needs to let the water in the fish tank form an ecological environment by itself, so some filter materials are needed to attach various aquatic flora.

Organisms in the water need enough oxygen, so to increase oxygen, it can be aerated by equipment.

There are microorganisms in the water that can effectively clean up the organic matter in the fish tank, and there is no need to worry about excess oxygen, so you need to put enough beneficial bacteria and aerobic bacteria into the bathtub, which is conducive to the formation of a microecological balance.

Tap water is rich in chlorine and cannot be used directly to raise fish, but it can be treated to raise fish. You can add an appropriate amount of chlorine-dissolving agent to tap water, and at the same time take the water to the sun for a few days to oxygenate and remove chlorine. In addition, pay attention to frequent water changes to ensure that the water quality is clean.

Chlorine in tap water has a strong penetrating effect on fish, it makes the mucus secreted by the fish lose its protective effect on the fish, resulting in a serious imbalance of electrolyte metabolism in the body, and suffocation and death in a state of hypoxia. Therefore, it is possible to add some chlorine-dissolving agents to the tap water.

2. Sun exposure

Untreated tap water can not be directly used to raise fish, you can use a basin of tap water, take it to the sun and expose it to the sun for 2 to 3 days, the sunlight can dechlorinate and oxygenate the tap water, turning "dead water" into "living water".

3. Cooling method

Tap water needs to be changed frequently, and you can change one-fifth of the water every day to keep the water clean enough. When you find that the tap water in the fish tank is green, this water is more likely to cause fish diseases, so you can replace all the water.

Before raising water, it is necessary to clean and disinfect the fish tank and filtration equipment, and it is best to use potassium permanganate solution to fully disinfect the treatment. After that, tap water is added to the fish tank, the filtration circulation device is turned on, and it is allowed to stand for a few days to remove chlorine. Then put nitrifying bacteria into water for three to five days, and then put it into the tank fish test, if the tank is successful, you can raise fish.

1. Wash the cylinder and disinfect it

Before raising fish, the newly bought fish tank should be cleaned and disinfected, washed with clean water, and then fully disinfected with potassium permanganate. If there are decorations such as sunken wood and stones, they also need to be cleaned and disinfected.

2. Add water to remove chlorine

After cleaning the fish tank, add tap water to the fish tank, because the tap water contains a lot of chlorine, so we have to let it stand for a few days, so that the chlorine in the water can volatilize, and the filtration system, heating system and other equipment are equipped.

3. Nitrification and water cultivation

In order to make the water quality more suitable for fish farming, nitrifying bacteria can be added to the fish tank, at the beginning of the water in the fish tank may become mixed, you can put an appropriate amount of rain division in it, and turn on the circulation filtration, after which the water will slowly become clear, it generally takes three to five days, and then the water is almost raised.

4. Put the fish in the tank

After the water is raised, don't be in a hurry to put the fish in it, it is best to put a few fish in the tank to try to see if the ecology of the fish tank is suitable for the survival of the fish, if the tank is successful, and then put the fish into the feeding.

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.
