Aquarium lighting, solar energy lamp related knowledge

1, what is light? The importance of light and water, the water of the sea creatures of light is a kind of energy. Aquatic plants with light energy, carbon dioxide and water in photosynthetic function, making glucose need nutrients supply water itself, such as by-product for oxygen. And the need of oxygen is adequate to provide to fish breathe. Also, the water of the sea creatures in cylinder some algae ( 藻类) (or so-called symbiotic algae Zooxanthellae） Through light photosynthetic function and growth, also provide software ( 珊瑚,无脊椎动物) Such as need. So, regardless of the aquatic plants or sea creatures sink all needs to borrow the right amount of carbon dioxide (provided by artificial 二氧化碳) Combined with light energy for photosynthesis, symbiotic algae and plants to reproduce or grow, fish or sea creatures or breathing or feeding algae, light energy, so as to pass to form a symbiotic food chain. On the other hand, the algae plants or lack of light, it will fade or wither and die directly. Relative, fish or sea creatures, no attachment also will not escape the fate of death, the full aquatic or ecological cylinder that is unable to form sea creatures. 2, the understanding of the natural light and artificial light source the light of nature, in the sunlight. So, no matter on land or sea creatures all participation of this light and pay the food chain transmission and be able to survive and develop. In the same way, create a ecological cylinder cylinder aquatic or sea creatures, necessarily don't lack of light. Home aquarium tank taking natural light source, however, is bound to is difficult. The sun light all-encompassing, scientists from the spectrum of sunlight precipitate in addition to the human eye can perceive visible light, such as red, orange, yellow, green, blue, indigo, ultraviolet; The sun still has the infrared light, ultraviolet, X-ray and laser light, and other imperceptible not visible to the naked eye. And the plants in the nature whether land or sea receive the sunlight (containing Visible and invisible light) Whether to accept according to the order? Or plant its own mechanism can take its required and rule out other unnecessary light, since it was established to research or a certain part of the hypothesis. But science with each passing day, the scientists from the analysis of the simulated sunlight light out useful light source, and produce a similar to the sun, plants, strong photosynthetic arranged, full spectrum light tube, software, and arranged the crawler lamp, uv cut tubes, PL lamp, fluorescent lamp, mercury lamp artificial light, etc. Although biological aquatic or sea ecological cylinder is a microcosm of mimic natural ecological, but also system simulation, only hard is equal to the real image of nature.
