How to survive the winter in the big tank of fish in the yard, how to keep fish in the big tank in t

Fish farming in a large tank in the yard, winter method:

First of all, you can do a good job of keeping warm, you can bury half of the fish tank in the ground, and then wrap it in discarded clothes or quilts, remember that the edges of the fish tank cannot be completely closed, you need to leave a vent. In addition, the fish tank needs to be filled with more water, because the water is too shallow and easy to freeze, so the fish tank is easy to break, and it is difficult for the goldfish in it to survive the winter. You can also add a moderate amount of salt to the water, which will prevent freezing.

How to choose a garden fish tank?

First of all, the shape of the tank should be selected according to the number of goldfish to be raised and the location of the fish to be placed. There are round, rectangular and polygonal fish tanks, and you can choose according to your preferences and uses. Secondly, pay attention to the length of the fish tank, the length can be selected according to the size of the placement, and it can also match the size of the lamp, which will have a better effect and be more affordable.

When buying a fish tank, we should observe its raw materials, which we often see in our daily life.

and materials such as glass. Glass can be divided into ultra-clear glass.

and float glass.

Generally, ultra-clear glass will be brighter and have better light transmittance, but it is also more expensive. The light transmittance of acrylic material and ultra-clear glass is about the same, which is suitable for making some fish tanks of the opposite sex.

When buying a fish tank, you should also consider what kind of fish you want to raise, so as to choose the corresponding fish tank and filtration system. If you don't need to think about it, of course, the more filtration systems the better, because this is an essential part of the fish tank.

In winter, it should be moved to the house.

The most difficult thing to keep fish in the yard is to control the temperature in winter, because when the temperature drops, the fish will lose their appetite, which will affect its survival. You can bury half of the tank in the soil and cover it with clothing, but do not block the edges and ensure the flow of gas. Add some water to the tank appropriately, less water is easy to freeze, and you can also sprinkle some salt into it to prevent this from happening.

1. Reduced feeding: In winter, fish farming should first control feeding, because in a low temperature environment, the appetite of the fish will also be attenuated, and if you feed too much, the food that is not eaten will become bait, thereby polluting the water quality. Of course, if you can maintain a high water temperature, you can feed normally.

2. Postponement of water change: The deterioration rate of water quality is usually related to temperature, which deteriorates quickly in summer and slows down in winter, so water quality can be better maintained and does not need to be changed too frequently. If you change it every three or five days in summer, you can change it once a week or two in winter.

3. Pay attention to heat preservation: If you are raising tropical fish, you must pay attention to heat preservation in winter, and the water temperature should not be lower than 20, otherwise the fish will be frozen to death. Even if it is a wide-temperature fish, the low temperature should not be lower than 5, otherwise it will affect its survival.

Because the courtyard fish tank is placed outdoors, it will inevitably cool down in winter, so the fish inside will be affected, and the appetite will be lost at least, and the fish will be frozen to death at worst. To avoid this, you need to keep warm. Usually, the fish tank should be buried in the soil, and the part that exposes the surface can also be wrapped with a quilt, but not completely closed, otherwise it will lead to air impermeability, and a little more water should be added to the tank.

1. Pay attention to the temperature: the first thing to pay attention to when raising fish in winter is to pay attention to the temperature, for the wide-temperature fish, the water temperature does not need to be too high, and it can be kept above 5. However, if it is a tropical fish, the temperature must be controlled at about 20, and if you are in a low temperature environment for a long time, the fish is likely to freeze to death.

2. Pay attention to feeding: Fish are ectotherms, so their vitality will be affected by temperature, and appetite is no exception. With the onset of winter, the temperature gradually decreases, and the feeding should also be reduced a little bit, so that the food it cannot eat does not become bait and pollute the water quality.

3. Pay attention to water change: fish farming needs to change water, and the cycle of water change is often related to the season. In summer, the temperature is high, and the water body is easy to deteriorate, so it is necessary to change the water frequently, and in winter, the water change does not need to be too diligent, it is no problem to change it once a week or two, and the temperature is best to be consistent before and after the water change.

Summary. Water. First put the water in the fish tank 1 3 or 1 5, the general fish tank has a water outlet, we can directly connect a PVC hose at the water outlet, connect one end of the hose to the fish tank outlet, and the other end into the bucket or basin, so that you can directly discharge the water in the tank.

Pay attention to the size of the hose must be selected appropriately, we can measure the size of the outlet first, and then buy the hose to avoid not being connected or too large to leak. Also, the hose can be as long as possible in case you need it.

If your fish tank does not have a water outlet, we directly use a scoop to fill the water outside, pay attention to scooping the water lightly, to avoid excessive force caused by the violent agitation of the water in the tank, so that the dirt and impurities at the bottom of the water will rise, resulting in the water becoming turbid.

Add water. After the water is placed, we gently add the prepared tap water that has been exposed to the sun for 1-2 days into the fish tank little by little to make up for the amount of water that has just been released. Remember to take this step gently and slowly to avoid the water becoming cloudy.

The basic principle of changing the water in winter is: if there is a filter and an oxygen pump in the fish tank, it is recommended to change the water once every 3-5 days, and change the water in the tank 1 3 at a timeOn the contrary, change it once every 2-3 days, and replace 1 5 of the water in the tank at a time. The choice of time to change the water in winter:

It is best to choose a sunny afternoon, which is conducive to the volatilization of chlorine in tap water and reduces the temperature difference of tap water. Control of water temperature trace section of Dongzi Chongyutian water change: It is recommended to use a thermometer to measure the water temperature in the fish tank and the new water that will be poured into it, and ensure that the water temperature difference between the new water and the water temperature in the tank is as small as possible, generally not more than 2-3 degrees Celsius.

1. Filtration device.

The filter supporting the worm hall is the steel demand of the fish tank and fish pond. Supporting filtration refers to the filtration volume, which should account for more than a quarter of the water body, and the hourly filtration volume is more than five times and less than eight times that of the water body. For example, if you add filtration to the side filter tank, the water quality will gradually stabilize.

2. Sedimentation chamber.

A supporting sedimentation chamber can be said to be a benefit once and for all in the process of water nourishment. It reduces a great burden for subsequent physical filtration and biochemical filtration. It can not only reduce the trouble of frequent cotton washing, but also extend the cycle of cleaning sludge accumulation.

3. Feed an appropriate amount.

The fish tank must be fed in moderation, and it must be eaten within 2 minutes, and the fish food that cannot be eaten is fished out and dried and fed again. Fish should always maintain their desire to eat. Don't feed too broken food, and don't put an end to fine foam.

4. The density of goldfish.

The density of fish farming determines the premise of water quality, after all, they are all small water bodies, and the natural conditions of large rivers are not comparable.

Fish farming in the northern courtyard for the winter mainly pays attention to keeping warm. Due to the low winter temperatures in the north, the water surface can even freeze, and if you don't control the temperature, the fish will freeze to death. In addition, as the water temperature decreases, the vitality of the fish will also decline, so do not feed it frequently, so as not to fall into the pond with a large amount of bait residue and decompose and pollute the water quality, which will have an adverse effect on the health of the fish.

1. Anti-low temperature: In winter, fish farming should first prevent low temperature, and low water temperature will have a greater impact on the health of the fish, and even lead to their death. If it is a tropical fish, the water temperature should be kept above 20, and the outdoor fish pond is generally not raised, so it can only be raised in a fish tank.

Wide-temperature fish, such as goldfish, koi, etc., can survive as long as 5 water temperature, but it is best to have a higher water temperature.

2. Prevention of hypoxia: there is generally no hypoxia in winter, because the temperature is low, the dissolved oxygen will be relatively high, but if the food is fed too much, it will also consume the oxygen in the water, and the lack of oxygen in winter is very dangerous, so it is necessary to use an oxygen pump to pump oxygen, and at the same time control the amount of feeding.

3. Anti-shallow water: the water for fish farming in winter must not be too small, if the water is less, the temperature is not easy to maintain, and it will increase the possibility of freezing, which is also not conducive to the survival of fish.
