3D dental scanner is most commonly utilized for cosmetic and restoration purposes, such as reconstructive therapy or oral surgery. 3D imaging allows for planning and customizing services for procedures such as bone grafts, implants, and root canals. 3D scanning is also often used to create 3D images for orthodontic treatment.

1. The water color is yellowish green and refreshing. It is good water. The color indicates that the shade of water is moderate, and the algae in the water body are mainly diatoms, followed by green algae and bare algae.
2. The water color is grass green and refreshing, which is good water. The color indicates that the water color is thick, and the algae in the water body are mainly composed of green algae and bare algae.
3. The water color is green and good. The color indicates that the water quality is moderate, and the color of the water is more common in a body of water to which organic fertilizer is applied. The algae in the water body are mainly diatoms, green algae, dinoflagellates and cyanobacteria, and the quantity is relatively balanced.
4. The color of the water is dark brown, which is good water. The color indicates that water quality is moderate and thin, and this kind of water color is more common in the water applied organic fertilizer. The humic substance concentration in this water-colored water body is larger, and the algae in the water body are mainly diatoms and cryptophytes, followed by euglena, green algae and dinoflagellates.
5. The water color is blue-green, gray-green and muddy, and the hot weather often appears on the water table on the side of the pond's breeze. The color indicates the aging of the water quality of the water body. The algae in the water body are dominated by blue-green algae, and the quantity is dominant.
6. The color of the water is grayish yellow, orange and turbid. There is a floating film of the same color on the water meter. It is bad water. The color indicates that the color of the water body is too thick, and the water quality is deteriorated. The algae in the water body are mainly cyanobacteria, and a large number of deaths have begun.
7. The color of the water is gray and it is bad water. The color indicates that a large amount of plankton in the water body has just died, the water quality has deteriorated, and the water body is seriously deprived of oxygen, and there is often the danger of flooding ponds.
8. The color of the water is dark brown and it is bad water. This color indicates that the water color is older and nearer to deteriorate. It may be due to the application of more organic fertilizers, and the content of humus in the water is too much. The algal species in the water body is dominated by cryptophytes, followed by blue-green algae and bare algae.
9. The water color is light red, and the color is often unevenly distributed, which is bad water. This color indicates that the otters in the water have excessive breeding and very few algae. This water-colored water body has a very low dissolved oxygen content and has turned into a water phenomenon with relatively thin water.
For brown water, the brown water formed at the early stage of fertilization is good water, and the water that turns from other water color to brown in the middle and later stages is bad water.
In short, by observing the color of water, we can know whether the water quality is good or bad, so that we can take effective measures (such as draining old water, injecting new water, fertilizing, etc.) to improve the water quality so that it always presents a pleasant water color. This is conducive to healthy fish and rapid growth.
Good or bad water quality is one of the key factors in the success or failure of fish farming. The criterion for judging whether the water quality is good or bad is whether or not it meets the requirements of “fat, live, tender, and coolâ€. Under normal circumstances, we can make simple judgments on water quality based on the color of water. Water color depends on many factors, but the water color in the pool water is mainly determined by the proportion of different plankton (mainly various algae) breeding. The phenomenon of a large number of plankton blooms resulting in denser water or even algal blooms and floating membranes is called bloom. Different algae grow in different bodies of water, but different algae contain different pigments, which results in inconsistent colors and different concentrations of pool water. Algae are the original producers in the water body and are the direct or indirect material basis for the growth of farmed fish. They have a very close relationship with fishery production. Here are some of the common water colors used in aquaculture production.
