Is the aquarium germicidal lamp effective? The working principle of germicidal lamp
Nowadays, lamps are not only used for lighting, but also used in other places. Among them, germicidal lamps are one of them. Many people still have some doubts. So is the aquarium germicidal lamp effective? What is the working principle of the germicidal lamp? Many people are not quite clear, BENWEI LIGHTING will explain it for everyone, let's take a look.

Is the aquarium germicidal lamp effective?
Regarding the germicidal lamp, there is no doubt that it has excellent functions in removing algae. In terms of sterilization, even if not all bacteria are all effective, it is by no means useless. As for the removal of insects, the effect may not be ideal. Of course, it may not be completely ineffective, but its ineffectiveness should be a fact. All in all, germicidal lamps should make a positive contribution to combating algae blooms.
There are several problems with germicidal lamps that you must pay attention to:
1. The germicidal lamp will not harm nitrifying bacteria
It sounds weird. Even though it is a germicidal lamp, it can kill bacteria in the water (at least most), but it won't kill nitrifying bacteria, yes! This is the fact that the germicidal lamp can kill the bacteria floating in the water, but the nitrifying bacteria that make a major contribution to the filtration of water have flagella, so they will adhere to the filter material (biochemical ball, biochemical cotton, ceramic beads), of course ! A very small amount of nitrifying bacteria has not yet implanted and will float in the water, but that very small part is not enough to shake your huge filtration system. In addition, some experts have studied that nitrifying bacteria that have not yet attached to the filter material have no purification function for water quality. In other words! Those nitrifying bacteria that have been killed die are not a pity.
2. A very small water flow is required for the effect of the germicidal lamp to be good
When you use a germicidal lamp, you must use a low-efficiency motor to pump water into the germicidal lamp tube. The slower the better, so as to ensure that every drop of water is irradiated by the germicidal lamp for a longer period of time, which is superior. Effect.
3) The germicidal lamp does not need to be used for a long time
The service life of the germicidal lamp is short, and the efficiency is usually greater after half a year. The timer can be used for a few hours a day, and its function is sufficient. Saving money is also important! In addition, it is best to turn on the germicidal lamp when the lamp is turned off. The effect should be better. When the lamp is turned on, it is when the algae is most active.
4. Don't administer medicine
No one can guarantee whether the germicidal lamp will have a chemical effect with your medicine. When the medicine is prescribed, not to turn on the germicidal lamp is the correct way to ensure safety.
5. Convert nitric acid to nitrous acid
Yes, the use of a germicidal lamp will convert nitric acid with low toxicity into highly toxic nitrous acid. Therefore, the water inlet and outlet of the germicidal lamp must be different. The water inlet is after the filter material and the water outlet is before the filter material. So, in the water After passing through the germicidal lamp, the nitrous acid produced by the nitric acid can be immediately converted back to nitric acid through the filter material. This process sounds scary, but in a sound nitrification system, it is easy. In other words, please temporarily Do not use germicidal lamps to ensure safety. Please pay attention to the aquarists who do not change the water for a long time! There may be too much nitric acid in your aquarium, and using germicidal lamps at this time may indeed cause a heavy burden on the filtration system. It is worth noting.
6. The effect of germicidal lamp
As mentioned before! Whether the function of the germicidal lamp is effective against bacteria, the key lies in the wavelength of the germicidal lamp, which is the most effective sterilization band. The strongest wavelength in the band is 253.7nm. The question is, is the wavelength of the germicidal lamp you bought is correct? God knows! I can only tell you that such a wavelength is absolutely harmful to the human body. The shell of the germicidal lamp requires special technology. Therefore, it can be concluded that cheap germicidal lamps can only remove algae. As for sterilization, it is not optimistic. In other words, there is no special shell to resist harmful wavelengths, and its sterilization function is questionable. In other words, there is no germicidal lamp shell that can resist the correct wavelength. Based on safety, it is impossible for the lamp inside to have a wavelength of 253.7mm. of.

The working principle of the germicidal lamp:
The germicidal lamp is actually a low-pressure mercury lamp. The low-pressure mercury lamp uses a lower mercury vapor pressure (<10-2Pa) to be excited to emit ultraviolet light. There are two main emission spectral lines: one is 253.7nm wavelength; the other is 185nm wavelength, both of which are naked eyes Invisible ultraviolet rays.
The germicidal lamp does not need to be converted into visible light. The wavelength of 253.7nm can play a good sterilization effect. This is because the cells have a law of absorption of light waves. Ultraviolet rays at 250~270nm have the maximum absorption, which is absorbed. Ultraviolet rays actually act on the genetic material of cells, namely DNA. It plays a kind of actinic effect. The energy of ultraviolet photons is absorbed by the base pairs in DNA, causing genetic material to mutate, causing bacteria to die immediately or unable to reproduce their offspring to achieve sterilization. the goal of.
