Germicidal lamps, as the name implies, mainly play a role in sterilization, disinfection, also known as UV lamps, is a lower intensity UV lamps. It uses low mercury vapor pressure ( <10-2Pa ) is excited and send out ultraviolet light, its hair line has two main: one is 253.7nm wavelength, the other is 185nm wavelength, these two are invisible to the naked eye ultraviolet. 253.7nm wavelength of the spectrum can play a very good bactericidal effect, the main principle of bactericidal according to the cellular absorption spectral pattern of light waves: cellular The wavelength of 250-270nm between the maximum amount of ultraviolet absorption, and the absorbed ultraviolet light can act on the cellular genetic material (DNA), so that it produces a photochemical effect, ultraviolet photon energy is absorbed by the DNA in the base pairs, causing the genetic material to mutate, so that the bacteria immediately die or can not reproduce offspring, to achieve the purpose of sterilization.
So, generally we keep ornamental fish in the process, when will use the sterilization lamp?
First, the fish tank burst bacteria
The fish tank burst bacteria is generally manifested in a short period of time the water from clear to turbid. Fish tank water burst bacteria can be used to inhibit bacterial reproduction or kill bacteria after germicidal lamps. In this case, you can change part of the water, turn on the germicidal lamp for 2 hours, turn off the lamp and add nitrifying bacteria can be improved.
There are many reasons that lead to fish tank bacteria, such as: under too many fish, feeding and fish excretion of organic matter produced by the amount of excessive bacterial reproduction of heterogeneous camps, or a large number of one-time cleaning of the filter media, etc. can lead to fish tank bacteria.
Second, green water
Green water is mainly due to the water body caused by too much chlorella, chlorella in the direct sunlight in the tank will be a large number of reproduction, and its reproduction rate is very fast. In fact, green water is not harmful to ornamental fish, but it will greatly affect the ornamental and aesthetic. Therefore, many fish friends will try every possible way to eliminate chlorella after finding the green color in the fish tank. Fish friends tried a variety of methods, found that the use of germicidal lamps or the best results, germicidal lamps can not only inhibit the reproduction of chlorella, but also kill it, especially at night, chlorella daytime is particularly active, but at night it will be all aspects of its function will be at a low ebb, the use of germicidal lamps will play a multiplier effect at this time. Used every night, continuous use for a few days, the green water situation will have obvious improvement.
Although germicidal lamps are very helpful in dealing with sudden water problems in aquariums, they should not be used continuously for a long time. Because germicidal lamps on all bacteria will play a role, whether it is beneficial or harmful bacteria, will be killed, so in the use of the following points need to pay attention to:
1, germicidal lamps mainly rely on ultraviolet light to play a bactericidal effect, and ultraviolet light on the human body is also damaging, so in the use of germicidal lamps should pay attention to can not be directly irradiated to the human skin, especially the eyes.
2. Avoid using it in the main tank, it will directly irradiate the fish body surface and affect the normal growth of fish. When you use it, try to use it in the filter tank, and try to be far away from the filter media, and there should be a block in the middle of the filter media to minimize the loss of nitrifying bacteria.
3, can not be used continuously every day for a long time, to avoid causing the aquarium water body nitrification system is not sound. Once stop using it, it is easy to cause the death of fish.
How to use em bacteria tablets in fish tank with uv germicidal lamp
EM bacteria in the fish tank need to be used correctly in order to make it play the greatest effect.
My usage is like this:
1. EM bacteria need to be used in conjunction with the filtration equipment, as shown in the picture below
Inside the filter box, you need to add the necessary filtering material, in order to cooperate with the growth of beneficial strains of EM bacteria.
2. Bacteria house is necessary, I choose the bacteria house is the following picture of the ceramic tube, small size and to be porous, mainly in the bottom of the filter box on a layer, and in the bottom of the aquarium properly put some (may not need to lay a layer)
In the filter box, ceramic tube needs to be laying on the top of a layer of filtering material, I chose to use a better three-layer filter material (mainly filtering some fish feces and other impurities, after all, the bacterial digestive capacity, the filtering material should be used as a filtering material, and it will be used to filter the fish. After all, the bacteria's digestive ability is also limited)
3. When these are ready, you can open the tank, open the tank is very simple, first put the tank full of water, and then let it stand for two days, mainly to remove chlorine in the water. After that, the key came, EM bacteria is not directly poured into the fish tank, but the EM bacteria liquid plus a small amount of water, evenly sprinkled into the inside of the filter box, and open the upper filter, so that the water in the fish tank through the upper filter flow up. This process is to let the EM bacteria take root and multiply in the filter box first. When the EM bacteria and the upper filter equipment began to work 24 hours later, you can put in the need to raise the fish, and normal feeding. EM bacteria I chose is the following YiFuYuan EM liquid, because it is easy to use
4. Usually in the feeding of the fish, you can also add EM bacteria (beneficial bacteria in the fish belly survive better, can make the fish eat more active, and digested more thoroughly, and at the same time promote the fish resistance), the way is to add EM bacteria (beneficial bacteria in the fish belly better, can make fish eating more active, and digested more thoroughly, and at the same time promote the fish resistance). Resistance), the method is to put the fish food to be fed in a small cup, pour 1/3 diluted EM bacteria liquid, stir and leave it for 20 minutes, after the fish food absorbed the EM bacteria liquid, feed the fish food. Please turn off the top filter when you feed the fish, and then turn it on again when the fish finish eating. Generally at the beginning, I open it every night. After that, I turn it on every few nights.
5. After one month, the micro-ecology of the tank will be formed. After the oxygen and open on the filter is a must, the filter box in the filter media only need to clean the three layers of filter media in the top layer of the white can be, the other do not have to clean. There is no need to change the water at all. However, even without changing the water, I will regularly pump out a little bit of water from the bottom of the tank, because this water is very suitable for watering the flowers, in the bottom of the fish waste that has not been sucked out by the upper filter at the same time, but also to bring the water to the soil of the plants that have become alive with the propagation of the EM bacteria and nitrate and other ingredients, it's really a one-two punch. After pumping out the water, new water needs to be added, and the newly added water must be left to dechlorinate for a few days. And when the new water is added, the fish food fed on this day can be treated with EM bacteria to increase the balanced number of EM bacteria in the water.
Germicidal lamps How to useThe correct use of ultraviolet germicidal lamps
The scope of application of ultraviolet lamps is used for indoor air and on the surface of objects and the disinfection of water and other liquids. UV lamps are used to destroy pathogenic microorganisms in the external environment, cut off the transmission pathways of infectious diseases, and block the spread of infectious diseases, so as to achieve the purpose of protecting human health. UV disinfection lamps, mainly used for air disinfection.
1, UV lamp hanging height. Should be hung vertically, 2-2.5 meters from the ground.
2, the range of ultraviolet lamps used, sterilization ultraviolet lamps inside the surface of the line issued by the c-wave, its wavelength range of 200-270nm, sterilization of the center wavelength of 253.7nm. in the case of sufficient ultraviolet intensity and irradiation time, can kill all microorganisms. However, the penetration of ultraviolet light is extremely weak, its irradiation intensity and distance squared is inversely proportional to, and only in the irradiated surface to play a bactericidal effect. At present, our country now produces the types of Mainly these: power in 15w, 20w, 30w, 40w At present, we use the most is 30w ultraviolet lamps, the requirement is that each cubic meter area up to 1.5w.
3, each ultraviolet lamp lamp cumulative time of 1,000 hours, more than 1,000 hours, it should be replaced in a timely manner new ones. New replacement to indicate the replacement time, and re-accumulation of the use of time.
4, ultraviolet lamp use process, should keep the surface of the ultraviolet lamp clean, generally every two weeks with an alcohol cotton ball sassafras test, found that the surface of the lamp has a gray layer, oil, should be sassafras test at any time.
5, ultraviolet lamps should be sterilized each time for 30-60 minutes.
Therefore, to master the existence of ultraviolet disinfection lamps and the use of methods, the correct installation and use of ultraviolet lamps, to eliminate or reduce the impact of ultraviolet lamp disinfection factors.
uv germicidal lamp on brown algae usefulgermicidal lamp germicidal lamp is to remove harmful bacteria and moss does not matter
1, manually clean up the aquarium indoor after all, less moss
2, large fish and scavenger
3, small fish moss rat algae shrimp
not clear or ah not clear not ah not clear, not a bit of medicine, a little bit of nitrobacteria, pavement sand, the natural environment, and occasionally change the water. I can't get sunlight in my indoor tank, so I use a Coke bottle with a pump and hang it out the window for an outdoor cycle, and it's done in the middle of the day.
UV germicidal lamps are useful for grass tanks
grass tanks put germicidal lamps, then the aquatic plants can not be raised, and germicidal lamps can not be put directly into the tank, or fish also die, to put also put the filter box, anyway, is not to let the light directly to the aquatic plants and fish, can you understand it?
What is the difference between uv germicidal lamps and uv c germicidal lamps
UV germicidal role is mainly the ultraviolet C section, so the general germicidal lamp is the UV c germicidal lamp.
The fish must use germicidal lamps, how to use
Germicidal lamps are good for fish, do not need to be used, but the effect is not generally good. Upper filtration with a lampshade, low filtration can be used lamps
aquarium UV germicidal lamps placed next to the filtration bucket sterilization can be to the role?No, it must be immersed in water.
Usually do not recommend using, because the germicidal lamp can also kill the nitrifying flora in the water.
What is the difference between uvc germicidal lamps and uv germicidal lamps?UV germicidal lamps said inside the industry are UVC germicidal lamps. Because only UVC sterilization effect is the best, so UV mercury lamps and UVLED are basically UVC wavelength 254nm sterilization. UVLED light source is generally biased 260-275nm.
How many W uv germicidal lamps should be used in a fish tank with a 60The following for reference
How many w germicidal lamps are used in a fish tank
It depends on how much space is available in the filter box or the filter box
It depends on how much space is available in the filter box or the filter box.
uv germicidal lamp can not be placed directly in the fish tank, direct exposure to the fish will cause injury to the fish
generally placed in the filter box
power wattage is different, the length of the germicidal lamp is also different
generally 80 cm below the fish tank for 5 w germicidal lamp, the length of the tube is about 17 cm
1 day not more than 4 hours
the number of hours of the lamp is not more than 4 hours.
