Fish culture can cultivate one's temperament. A tank of fish can also be used to decorate and beautify the indoor environment. However, it should be noted that if the fish tank is not properly selected, it will not only cause bad fish, but also pollute the indoor environment, thus affecting human health. Therefore, if you put a fish tank at home, you can raise it to benefit your health. So, how is it called Huiyang?
Some suggestions for new fish farmers
1. If you decide to raise fish, don't rush to buy fish tanks and equipment. Instead, go diving in various aquarium forums to supplement the basic knowledge of fish farming. Although fish farming is an interest, it also needs money and energy. The more famous forums are South American aquarium, Longding aquarium and so on. No matter what fish you plan to raise, there is a complete set of basic knowledge. If you have decided what kind of fish to raise, you should know more about how big the tank is used for raising this kind of fish, what kind of filtration is used, how much temperature is suitable, how many are suitable, which equipment is necessary and which equipment can not be used. The principle is to buy less if you can buy less.
2. With a preliminary understanding of fish culture, you can open the VAT to raise water. Just follow the steps of opening the tank in the forum, such as oxygen explosion, 24-hour filtration, adding nitrifying bacteria (not necessary), etc. the time of water cultivation depends on how patient you are. Seven days is not less than a month, but it should not be less than three days. The purpose of these three days is to remove the residual chlorine in tap water. As for whether it is necessary to do so, the first thing is to see whether you have the patience. The second is to see whether the fish you start is delicate or not. The main function of releasing the fish is to test the suitability of water quality and speed up the establishment of nitrification system.
3. When choosing fish in the fish market, pay attention to see and ask more about the status of the fish and the arrival time of the fish. If you can fish by yourself, don't let the boss fish for you. If you can choose smart fish, don't make do with less choices. Choosing fish is better than over, or you're looking for trouble for yourself. As for the method of selecting fish, there are a lot of them on the Internet, which can be searched out at any time. Don't be too troublesome. Fish farming itself is a trouble!
4. As for new fish, we must pay attention to it. They are all bought by ticket. If you can pass the water according to the correct method, don't throw it in blindly. It is only good and not bad to spend an hour to water the fish. Many novice new fish died without two days, which is related to the lack of water. Fish farming is a trivial matter, including feeding and changing water. If one thing is over done, the fish will die to show you. There is no ambiguity at all.
5. Daily maintenance is mainly about feeding and changing water. It is said that water should be raised first in fish farming, and the hard problem of filtering strength should be put aside. The main reason for the deterioration of water quality is the method of changing water and feeding. Fish can't die of starvation, even if you don't feed it for a few days, but if you feed too much, it's hard to say. The fish are not only prone to indigestion and enteritis, but also the destructive power of the residual bait to the water quality is very strong. It may be two or three days, and your fish will die. So keep in mind the principle of feeding fish. It's not recommended to feed fish frequently.
6. As for the replacement of water, two principles should be followed: temperature and quantity. The new water can be one or two degrees higher than the old water, and the minimum temperature must be the same as the original water tank. It is better not to change water more than one-third, once a week. If you find more residue and fish at the bottom of the tank, you should also pay attention to draw out and replenish the same amount of new water at any time. If it is the treatment of fish disease, we can say otherwise. During fish disease, changing water more is to reduce the number of bacteria. Compared with the damage caused by changing water more, we prefer to dilute the bacteria.
7. The attitude towards fish disease is to prevent and prevent. The main method is to regularly send or sterilize some drugs, and the basic method to prevent fish disease is to maintain the stability of water quality, including maintaining constant temperature, regular water exchange, regular feeding, etc. As for the treatment of fish disease, it is not recommended that new drugs be used, even if the drug is used separately, and the temperature of oxygen explosion is also increased while the drug is used.
Daily maintenance of fish tank
Control stable water quality
·Stable salinity
When you first prepare a tank of seawater, just pay attention to the ratio of 30 liters of seawater per kilogram of seawater salt. Most of the adjusted seawater pH was maintained at 8.0 ~ 8.4, the density was 1.020 ~ 1.024, and the nitrite content was below 0.1 mg / L. After the aquarium is in operation, the water will evaporate, which will lower the water level and increase the density of water day by day. It is necessary to add fresh water at intervals. After replenishing fresh water, you should check whether the density of the water is appropriate. It should be emphasized that the temperature must be below 25 ℃. At present, the most advanced salt content measuring equipment is the conductivity meter for measuring seawater. The conductivity value of Standard Seawater should be between 47 ~ 51 msgms / cm. We usually use buoy or box densitometer.
·Stable pH
Anyone who has raised sea water ornamental fish knows that maintaining a stable pH in the aquarium is extremely important. Because the pH of the water in the aquarium will drop due to the residues of nitrite and nitrate, it must be detected regularly to avoid the deterioration of the water quality, causing fish discomfort and infection. It should be noted that most of the common large and small white spot diseases of marine ornamental fish are caused by excessive changes in pH. special attention should be paid to adjusting pH and properly monitoring its changes during the treatment period, which will make it easier to control the white spot disease of sea fish.
Generally speaking, the pH and the concentration of nitrite and nitrate should be detected once every two weeks in the aquarium. The pH should be maintained between 7.9 and 8.3. If it is a newly established seawater aquarium, the number of pH tests is the best. When the pH of the water in the aquarium rises or decreases, it can be adjusted by alkali increasing agent (increasing pH) or acid increasing agent (lowering pH), but it should be carried out slowly. It can not be increased or decreased too much at a time, generally not more than 0.1. If the adjustment is more than 0.1, it can be carried out several times and gradually adjusted to the required pH. However, if the water in the aquarium has just been adjusted and the pH drops quickly, it will remind you that the water cluster tank needs to be changed.
·Regular partial water change
Nitrate can not be decomposed by nitrifying bacteria, and some removal methods are too expensive. When nitrate accumulates to a certain extent, algae such as Chaetoceros, hairy algae, filamentous algae, brown algae and even red algae will grow in large numbers. This not only affects the beauty of the aquarium, but also causes some damage to the fish or organisms, and then destroys the ecological balance of the aquarium, leading to the flooding of the aquarium. Therefore, in daily management, it is necessary to change water regularly and replace 10% of seawater every month (using sand and gravel suction device to pump dirty water under sand and gravel). Pay attention to add the new seawater slowly, and draw in with a thin tube to avoid the water quality changing too fast and stimulating the fish.
·Check the filter system regularly
① If you use an external filter, be sure to connect the water pipe after cleaning. Note that the pump can not only filter the water in the tank, but also pump out the water in the aquarium.
② Often check whether the water outflow from the filter is normal and whether there is blockage. In addition, the biological sponge or filter element of the first layer blocking dirt should be cleaned regularly and replaced regularly.
③ The activated carbon should be replaced regularly.
④ Clean the dirt in the protein separator regularly.
⑤ Clean the filter regularly (described above).
Appropriate lighting appropriate lighting refers to the light that can maintain the survival and reproduction of unicellular zooxanthophyta in invertebrate symbiosis. We have already discussed that different organisms have different requirements for light, which can be divided into strong light, medium light and weak light. For example, an aquarium with a length of 130 cm and a water depth of 60 cm is equipped with two 150 Watt metal halogen lamps, which are 40 cm away from the water surface. It is enough to irradiate for 10 hours every day. You can infer whether your aquarium has maintained proper lighting conditions.
Proper flow
·Circulating water flow
In the process of nitrification, nitrifying bacteria need to consume extremely high oxygen. Therefore, how to send sufficient oxygen and organic matter to be decomposed in water into filter materials in the water circulation process, so that nitrifying bacteria can decompose it effectively, is an important consideration in the design of circulating water flow. We must realize that too much water flow will make nitrifying bacteria unable to establish a foothold and form a dense nitrification network. Too slow water flow can not achieve the function of transporting oxygen and organic matter, resulting in some dead corners, resulting in anaerobic zone, accumulation of unnecessary ammonia and hydrogen sulfide and other waste gas, which is not conducive to the stability of water quality.
·A strong flow of water
The movement of water allows the aquarium to be constantly replaced in every place in the aquarium, such as corners, cracks, caves, and water around the coral. We must try to prevent areas where there is still water flow. The movement of water can make the metabolites of unicellular zooxanthophyta on invertebrates be removed by water flow. Organic food will also be transported to the habitat by water flow, making it easier for them to eat.
To sum up, the water flow in the aquarium is very important. It is ideal to use circulating water pump to make water flow at least 5 times per hour in the aquarium. It is better to use two pumps to change the direction of water flow every 6 hours, and timing switch is better.
Check the water temperature
In order to raise ornamental fishes and invertebrates in tropical seawater, the temperature of aquarium should be kept within the temperature range of natural tropical seawater, that is, between 25 ℃ and 27 ℃. When the temperature is lower than 20 ℃ or more than 30 ℃, calcium coral will stop synthesizing calcium, and when the temperature exceeds 15 ~ 32 ℃, most corals will die. Therefore, in the feeding management, cooling and heating equipment should be installed according to the situation, so as to prepare for high temperature in summer and severe cold in winter. When heating the aquarium in winter, because of the high conductivity of seawater, the heater with grounding wire should be used. In order to protect users. The best safety measure is to install a 24 volt low voltage heating system. If the number of fish heads is not correct, you must carefully find out the fish that did not come to eat bait and further observe these fish. Is it a poor appetite or do not want to get along with other fish? If death is found, it must be fished out immediately to avoid polluting the water quality. Is the death of the fish caused by disease and infection or by other fish attack and injury? Find out the cause. It should be noted that the sea water ornamental fish are very sensitive to any pressure or interference, so when observing the fish, do not use your hands with your eyes and try to avoid putting your hands in the aquarium.
Fish tank and household geomantic omen
Fish tanks should not be placed under the gods - it is not suitable to place fish tanks under any gods, especially under the God of wealth and the three stars of fortune, or else, it will be "Zhengshen water", and there will be money breaking!
The fish tank should not be aligned with the kitchen stove -- the fish tank should be aligned with the kitchen stove, which is very bad, because it will damage the health of the family.
The number of fish culture in geomantic omen is based on the number of Luoshu. A good way to have good feng shui at home is to raise some goldfish in the fish tank. It's best to keep nine goldfish, eight of which are red or gold, and the other is black. If your goldfish accidentally died, just buy it to make up for it. In geomantic science, we think that the reason why fish die is because it prevents bad luck for their families.
Don't keep goldfish in bedrooms, toilets or kitchens. Bedroom is even worse, you will suffer material losses, such as being stolen, or even robbed. Therefore, it is better to keep fish in the living room or outside the house. It is absolutely not wrong to put the fish tank in the north and Southeast. But it depends on the condition of the home.
If you want to put fish tanks into effect, you must pay attention to the spatial orientation of each house. The financial position of the house is suitable for the fish tank. It is generally in the diagonal position of the entrance and exit door. No sundries can be placed. The corner and floor can not be peeled and damaged. Don't put it in the center of the room. The southeast is rich and rich, and the success of business lies in the north. Therefore, it is advisable to place the fish tank in the south-east or the north. It is best to place the fish tank in the front of the bright hall, which can be used as the office landscape to design a beautiful fish tank with green eyes and vitality. It helps to relax the nerves, improve the spirit and expand the interpersonal relationship. The selection of Geely orientation should be based on the geomantic theory to calculate the planning space and orientation.
