If koi is raised outdoors or in a well-lit place, there is no need to use a lamp to enhance the light. If you breed in a poor light area, you need to use lamps to enhance the light. The purpose of brightening is to help koi develop better color. For example, Golden Dragon Koi and Red Dragon Koi will become more and more colorful only when they are well illuminated.
Different lamps need to be used in different breeding environments. If the koi is cultured in a place where the light is particularly bad, the metal halide lamp needs to be used for illumination. Metal halide lamps can produce white light close to sunlight, instead of sunlight on Koi. If the koi is raised in a low-light area, led lights can be used, and the advantage of led lights is energy saving. The white light and the blue light are turned on at the same time to realize illumination with different color temperatures and wavelengths, that is to say, the white light illumination provides light energy, and the blue light promotes absorption, which is beneficial to the growth of koi. If the koi care in a well-lit area, the use of incandescent lamps can be.
In general, the lights need to be on all the time. If it is a place with good light, it is enough to ensure that the light shines for four hours every day.
