The light in the fish tank can be of any color. The light does not have much effect on the fish. Only some fish with unstable colors are easy to fade under strong light, such as some black goldfish. In this case, set a timer to start Just switch off. In addition, with colored lights, the color of the fish itself will be distorted. I personally think that it is not conducive to appreciation. Generally, white is better.
As for the sterilization function, it is an ultraviolet light. The ultraviolet light itself is invisible to the naked eye and cannot be used for lighting. It can be turned on for up to 30 minutes at a time, and the fish must be removed and the person must leave, otherwise it will be hurt. Generally, it is sealed and installed inside the filter device.
Aquarium lighting uses the relationship between light and organisms, so that the light it emits can promote the growth of plants planted in the aquarium, because the carbohydrates (sugars) produced by photosynthesis are the oxygen feed for the aquatic plants. In addition, light has an absolute relationship with the growth of the pigment body of fish and the precipitation and absorption of vitamin D. Therefore, the rational use of the light source in the aquarium is an important condition for constructing an ecological environment suitable for the living creatures in the aquarium. There are mainly the following types of plant light tubes:
A, full spectrum lamp
The light color of this type of lamp is close to sunlight, the color rendering can reach 90, and the color temperature is 6500K. The original color of the aquatic plants and sea creatures is lifelike and the sunlight is very close to the aquatic plants and sea creatures, and it is in line with the growth of advanced plants. The spectral absorption curve fully meets the physiological needs of higher plants for light.
B, plant light tube
The main spectrum of this type of lamp is concentrated in the blue and red regions. Scientists have found that the energy values of these two wavelengths are very close to the efficiency curve of plant photosynthesis (it is even more significant for green plants). It is the best light source for plant growth. .
C, powerful photosynthetic tube
This type of lamp belongs to the enhanced brightness type of the plant lamp, but the spectral distribution in the red and blue areas is reversed with the spectral distribution in the red and blue areas of the plant lamp. The light surge is higher than that of the plant lamp. The lighter blue color is an enhanced brightness type lamp tube of the plant type lamp tube.
D, soft tube
This type of lamp is dedicated to stimulate the growth of symbiotic algae in a seawater biological tank. When irradiated with molluscs, it has a dreamy light blue color. It simulates a 6-10m natural deep-sea moonlight environment, provides essential nutrients for molluscs and stimulates peanuts. The growth of algae is an essential light source for marine organisms.
