How useful are germicidal lamps you know?

Germicidal lamps are one of the equipment that many fish enthusiasts always have on hand. This shows the status of germicidal lamp in ornamental fish keeping. In fact, many fish enthusiasts follow other fish enthusiasts to buy germicidal lamps, and know little about its role and use.

Germicidal lamps, as the name suggests, mainly play a role in sterilization, disinfection, also known as UV lamps, is a lower intensity UV lamp. It uses the lower mercury vapor pressure ( <10-2Pa ) is excited and issued by the ultraviolet light, its hair line has two main: one is 253.7nm wavelength, the other is 185nm wavelength, both are invisible to the naked eye ultraviolet. 253.7nm wavelength spectrum can play a very good bactericidal effect, the main principle of sterilization is based on the cellular absorption spectral pattern of light: the cellular absorption of wavelength between 250-270nm is large, and is absorbed by the ultraviolet light between 250-270nm. Between 250-270nm ultraviolet absorption, and the absorbed ultraviolet light can act on the cellular genetic material (DNA), so that it produces photochemical, ultraviolet photon energy is absorbed by the base pairs in the DNA, causing genetic material mutation, so that the bacteria immediately die or can not reproduce offspring, to achieve the purpose of sterilization.

So, when do we typically use germicidal lamps in keeping ornamental fish?

I. Fish Pond Bursting Bacteria
Fish pond burst bacteria is usually manifested in a short period of time the water from clear to cloudy. After the fish pool water burst bacteria can be used to inhibit bacterial reproduction or kill bacteria germicidal lamp. In this case, you can change part of the water, turn on the germicidal lamp for 2 hours, turn off the lamp and add nitrification fine

Bacteria can be improved. There are many reasons that lead to the bursting of bacteria in the fish pond, such as: too many fish, too much organic matter produced by feeding and fish excretion leads to a large number of heterocystic bacteria, or a large number of one-time cleaning of the filter media can lead to the bursting of bacteria in the fish pond.

II. Green water
Green water is mainly caused by excessive chlorella in the water body. Chlorella will proliferate in fish ponds with direct sunlight, and it reproduces very quickly. In fact, green water is not too harmful to ornamental fish, but it will greatly affect the viewing and aesthetics. Therefore, many fish lovers will try every possible way to eliminate chlorella after they find the green color in their fish pond. 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 functions will be at a low ebb, this time the use of germicidal lamps will play a multiplier effect. Use every night, continuous use for a few days, the green water situation will have obvious improvement.

Although, germicidal lights are very helpful in dealing with sudden water quality problems in fish ponds, they should not be used continuously for long periods of time.

Because germicidal lamps work on all bacteria, whether they are beneficial or harmful, they will be killed, so you also need to pay attention to the following points when using them:
1Germicidal lamps mainly rely on ultraviolet light to play a sterilization effect, and ultraviolet light on the human body also has damage, so in the use of germicidal lamps should be careful not to directly irradiate the human skin, especially the eyes.
2. Avoid using it in the main tank, it will directly irradiate the body surface of the fish and affect the normal growth of the fish. When using, try to use it in the filter tank, and try to be far away from the filter material, and there should be a block in the middle of the filter material, so as to minimize the loss of nitrifying bacteria.
3, can not be used continuously every day for a long time, to avoid causing the fish pond water body nitrification system is not sound. Once stop using it can easily lead to the death of fish.
