The funtion of fish tank lights

  The first function of the fish tank light is to better appreciate the fish you raise. The fish under natural light is not beautiful, but the fish under the light will be more beautiful. The fish also need light, which is helpful for color rendering.

There are many kinds of lights, some for watching fish, such as general red tube lights to make the fish more beautiful; some are dedicated to water plants, such as three-band tube lights; lights of various colors of blue, red and green are used on water plants of different colors , For example, the red grass should be added with blue tube on the basis of three bands and so on.

The main function of the light is to supplement the light in the absence of sunlight, making the fish more lively. According to the different species of fish, match the light with the corresponding color temperature; the white light is the most natural and the most real-looking. It is recommended to match a white light source. 6500k is most suitable for raising goldfish.

  Precautions for fish tank farming:

  It is strictly prohibited to change water in large quantities:

Extensive water changes can cause many problems, such as large fluctuations in water quality, collapse of the nitrification system, and fish catching a cold. Change the water once every 3 days, changing the water 1/3 to 1/5 once; changing the water does not wash the cotton, and the cotton does not change the water; when changing the water, do not pour directly into the tank and impact the fish body; Slowly inject into the cylinder wall;

  filtering system:

A powerful filtration system is a necessary condition for fish farming. The flow rate of the pump reaches 8-10 times that of the water body; the volume of the filtration system reaches more than 1/5 of the water body; the order of the filter materials is reasonable, such as: physical-biochemical-function; reasonable stocking density, reasonable daily maintenance, and no collapse of the nitrification system .

 Oxygen the trapped water:

Although trapped water can effectively remove chlorine, the water trapped for too long, especially in summer, the water that has been exposed for many days may have a peculiar smell. This kind of water is changed to the fish tank, which is harmful to the fish. The water trapped should pay attention to the control time, only 48 hours; try to use the aeration method to dechlorinate the tap water.

  Ultraviolet rays are a type of electromagnetic waves. When electrons in atoms jump from high energy levels to low energy levels, they release excess energy as electromagnetic waves. The stronger the energy of the electromagnetic wave, the shorter the wavelength. The wavelength that the human eye can see is 400nm-780nm (1nm=10-9m). To the naked eye, the electromagnetic wave of 400nm is displayed in blue and purple, and the electromagnetic wave of 780nm is displayed in orange and red. . Ultraviolet rays refer to electromagnetic waves with wavelengths shorter than 400nm. Because their spectrum is outside the purple region, it is called Ultraviolet (UV for short). Ultraviolet rays generally refer to electromagnetic waves with a wavelength of 100-400nm, and human eyes cannot see ultraviolet rays.

Ultraviolet rays with wavelengths of 100-400nm are UV-A, UV-B, UV-C and V-UV according to their effects on the human body and functions.

UV-A refers to ultraviolet rays with a wavelength of 315-400nm. UV-A can make human skin produce melanin and darken the skin.

UV-B is ultraviolet rays with a wavelength of 280-315nm. UV-B can cause cancer and cause skin wrinkles and aging.

The wavelength of UV-C is 200-280nm, of which the 254nm band has sterilization and disinfection effects.

UV-C with a wavelength of 240-270nm can directly damage the DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of cells and viruses, causing rapid death of microorganisms.

VUV185nm with a wavelength of 100-200nm can produce ozone, and ozone in the air or dissolved in water can destroy the cell walls of microorganisms by oxidation, causing the microorganisms to die immediately.

  Principles of UV Sterilization

All known life forms on the earth use DNA and RNA as the basis for reproduction and survival. Both DNA and RNA are composed of 4 chemical units

A--Adenine

T--Thymine

C--Cytosine cytosine, oxapyrimidine

G--Guanine guanine (basic component of nucleic acid)

  When the cell reproduces, the long chain in DNA opens. After opening, each long chain A unit will look for the T unit to join, and each long chain can replicate the same chain as the newly separated long chain and restore the original The complete DNA before division becomes the basis of new cells. Ultraviolet rays with a wavelength of 240-270nm can break the ability of DNA to produce proteins and replicate. After the DNA and RNA of the bacterial virus are damaged, the ability to produce protein and the ability to reproduce have been lost. Due to bacteria, viruses generally have a short life cycle, bacteria that cannot reproduce, viruses will die quickly.

  Little knowledge of aquarium, to understand the real function of fish tank germicidal lamp, correct use is very important!

  Photosynthesis is conducive to the production of oxygen by plants in the aquarium, ensuring oxygen in the water

  It overcomes the shortcomings of insufficient light in the wall-mounted fish tank, greatly improves the viewing of the fish tank, and is provided with a frame cover which can be made into a closed type, making the utility model more like an active picture and enhancing the viewing effect.
