Then, when do we usually use germicidal lamps in the process of raising ornamental fish?
First, the fish tank exploded.
Fish tank explosion usually shows that the water body changes from clear to turbid in a short time. After the fish tank water bursts, you can use a germicidal lamp to inhibit bacterial reproduction or kill bacteria. This situation can be improved by changing some water, turning on the germicidal lamp for 2 hours, and adding nitrifying bacteria after turning off the light.
There are many reasons for bacterial explosion in fish tanks, such as too many fish caught, too much organic matter produced by feeding and fish excretion, resulting in a large number of heterotrophic bacteria, or washing a large number of filter materials at one time, which can all lead to bacterial explosion in fish tanks.
Second, green water.
Green water is mainly caused by excessive Chlorella in water. Chlorella will breed in a fish tank with direct sunlight, and the breeding speed is very fast. In fact, green water does no harm to ornamental fish, but it will greatly affect the ornamental and aesthetic quality. So many fish friends will try their best to kill Chlorella after discovering that the fish tank is green. After trying various methods, the fisherman found that the germicidal lamp was the best. The germicidal lamp can not only inhibit the reproduction of Chlorella, but also kill it, especially at night. Chlorella is particularly active during the day, but at night, its various functions will be low. At this time, the use of germicidal lamps will have a multiplier effect. If you use it every night for several days, the situation of green water will be obviously improved.
Although germicidal lamp is very helpful to deal with sudden water quality problems in fish tanks, it cannot be used continuously for a long time. Because the germicidal lamp will work on all bacteria, whether it is beneficial or harmful, it will be killed, so you should also pay attention to the following points when using it:
1, germicidal lamp mainly relies on ultraviolet rays to sterilize, and ultraviolet rays are also harmful to human body, so be careful not to directly irradiate human skin, especially eyes, when using germicidal lamp.
2. Avoid using it in the main tank to directly irradiate the surface of fish, which will affect the normal growth of fish. When used, it should be used in the filter pool as far as possible, and there should be a barrier between it and the filter material to minimize the loss of nitrifying bacteria.
3. Don't use it continuously for a long time every day, so as to avoid the imperfect nitrification system of fish tank water. Once you stop using it, it will easily lead to the death of fish.
How to use the ultraviolet germicidal lamp em in the fish tank? EM bacteria need to be used correctly in fish tanks to maximize their efficacy.
My usage is this:
The use of 1 EM bacteria need to cooperate with the upper filtration equipment, as shown in the following figure.
In this filter box, necessary filter materials need to be added to cooperate with the growth of beneficial bacteria in EM bacteria.
2. A bacteria room is necessary. The bacteria chamber I chose is the clay tube shown below, which is small and porous. Mainly lay a layer on the bottom of the filter box and put some on the bottom of the fish tank (there is no need to lay a layer).
In the filter box, the clay pipe needs to be covered with a layer of filter material, and I choose a better three-layer filter material (mainly to filter some impurities such as fish manure, after all, the digestion ability of bacteria is limited).
When all this is ready, you can open the can. Opening the fuel tank is very simple. Fill the fish tank with water first, and then let it stand for two days, mainly to remove chlorine from the water. After that, the key point is that the EM bacteria are not directly poured into the fish tank, but a small amount of water is added to the EM bacteria solution and then evenly sprinkled into the filter box, and the upper filter is opened to let the water in the fish tank flow through the upper filter. This process is to let EM bacteria take root and multiply in the filter box first. EM bacteria and upper filtration equipment start to work 24 hours, and the fish that need to be raised can be put in for normal feeding. I chose the following Yi Fuyuan EM bacteria stock solution because it is easy to use.
4. When feeding the fish, you can also add EM bacteria (beneficial bacteria can survive better in the stomach of the fish, which can make the fish eat more actively, digest more thoroughly and improve the resistance of the fish). The method is to put the fish food to be fed into a small cup, pour 1/3 diluted EM bacteria stock solution, stir and stand for 20 minutes, and feed it after the fish food absorbs EM bacteria liquid. Attention, please close the upper filter when feeding fish food, and then open it as needed after the fish is finished. Usually at first, I drive it every night. After that, it will be held every few nights.
5. After one month, the basic micro-ecology of fish tank was formed. After that, it is necessary to aerate and open the upper filter. The filter in the filter box only needs to clean the white layer in the top three layers of filter material, and nothing else needs to be cleaned. There is no need to change the water at all. However, even if I don't need to change the water, I will regularly draw some water from the bottom of the fish tank because it is very suitable for watering flowers. While cleaning up the fish manure that has not been filtered and sucked up at the bottom, I can also bring EM bacteria and nitrate that survived in the water into the soil of plants, which really kills two birds with one stone. After the water is pumped out, it needs to be replenished with new water, and the newly added water must be allowed to stand for a few days to remove chlorine. When new water is added, the fish food fed on this day can be treated with EM bacteria to increase the balance of EM bacteria in the water.
How to use germicidal lamp correctly using ultraviolet germicidal lamp
The application scope of ultraviolet lamp is the disinfection of indoor air and surface, water and other liquids. Ultraviolet lamp is designed to destroy pathogenic microorganisms in the external environment, cut off the transmission route of infectious diseases, and block the spread of infectious diseases, thus achieving the purpose of protecting human health. Ultraviolet disinfection lamp, mainly used for air disinfection.
1. Hanging height of ultraviolet lamp. Should be suspended vertically, 2-2.5 meters from the ground.
2. The scope of use of ultraviolet lamp. The line emitted from the inner surface of the sterilization ultraviolet lamp is C wave, with the wavelength range of 200-270 nm and the sterilization center wavelength of 253.7nm, which can kill all microorganisms under the condition of sufficient ultraviolet intensity and irradiation time. However, the penetration of ultraviolet rays is extremely weak, and its irradiation intensity is inversely proportional to the square of the distance, which can only sterilize the irradiated surface. At present, domestic products mainly include these categories: power 15w, 20w, 30w, 40w. At present, we use the 30w ultraviolet lamp most, which requires an area of 1.5w per cubic meter.
3. The cumulative time of each ultraviolet lamp is 1000 hours. If it exceeds 1000 hours, it shall be replaced with a new one in time. The replacement time should be indicated for new ones, and the service time should be re-accumulated.
4. In the process of using the ultraviolet lamp, the surface of the ultraviolet lamp should be kept clean. Usually try alcohol cotton balls once every two weeks. Try it at any time when you find dust or oil on the surface of the lamp tube.
5, ultraviolet lamp disinfection time should be 30-60 minutes.
Therefore, it is necessary to master the existing problems and use methods of ultraviolet disinfection lamps, correctly install and use ultraviolet lamps, and eliminate or reduce the influencing factors of ultraviolet lamp disinfection.
Is ultraviolet germicidal lamp useful for brown algae? The germicidal lamp removes harmful bacteria, which has nothing to do with moss.
1. After all, there is very little moss in the manual fish tank room.
2, large fish scavenger
3. Small fish, lichens, mice, algae and shrimp
Just don't clean it up. If you don't clean up, you won't be drugged. A little nitrifying bacteria will pave the natural environment of river sand and occasionally change water to bask in the sun.
My indoor cylinder couldn't touch the sun, so I connected the water pump with a coke bottle and hung it outside the window for an outdoor circulation, which was completed in a short time without affecting the appearance at noon.
Note: My parrot is koi fish black, white and colored. Mary, phoenix tail, blue star, red star and lily street sweeper are mixed together. That is lively and beautiful, but the fish is in good condition. Too bright phoenix tail will be chased by other fish and eliminated by the environment.
Is ultraviolet germicidal lamp useful for straw vat? If you put the germicidal lamp in the straw jar, the aquatic plants can't be raised, and the germicidal lamp can't be put directly in the fish tank, otherwise the fish will die. If you put it in the filter box, you just can't let the light shine directly on the aquatic plants and fish, can you understand?
What is the difference between ultraviolet germicidal lamp and ultraviolet C germicidal lamp? The main germicidal function of UV is C-section ultraviolet light, so generally germicidal lamps are UV C germicidal lamps. ..
Is it necessary to use a germicidal lamp to raise arhat fish? How to use germicidal lamp is a good fish culture product, and it is not necessary, but the effect is not generally good. Lampshade for upper filtering, lamp tube for lower filtering.
Can the fish tank ultraviolet germicidal lamp be placed next to the filter barrel for sterilization? It's no use. It must be immersed in water.
It is not recommended at ordinary times, because germicidal lamps can also kill nitrifying bacteria in water.
What is the difference between uvc germicidal lamp and ultraviolet germicidal lamp? The ultraviolet germicidal lamps mentioned in the industry are all UVC germicidal lamps. Because only UVC has the best sterilization effect, ultraviolet mercury lamps and UVLED are basically sterilized with UVC wavelength of 254nm. The light source of UVLED is generally biased at 260-275nm.
How many W ultraviolet germicidal lamps should be used in 60 fish tanks for reference.
How many w germicidal lamps are used in the fish tank?
It usually depends on your filter box or the space of the filter box.
The ultraviolet germicidal lamp cannot be placed directly in the fish tank, and direct irradiation on the fish will hurt the fish.
Usually used in filter boxes.
Different wattage germicidal lamps have different lengths.
Generally, 5w germicidal lamp is suitable for fish tanks below 80cm, and the length of the lamp tube is about 17cm.
1 day, no more than 4 hours
