水族照明知识全介绍（Aquarium lighting knowledge） Aquarium lighting knowledge 1, what is light? The importance of light and water plants and sea creatures Light is a kind of energy. Aquatic plants are synthesized by light, carbon dioxide and water, producing glucose and other nutrients and supplying the water plants themselves, while by-products are oxygen. This oxygen is adequate for the fishs breathing needs. Likewise, certain algae (algae) or so-called symbiotic algae (Zooxanthellae) in the marine bio tank are grown by light synthesis, providing invertebrates (corals) and other requirements. So, whether aquatic or marine organisms are required by the artificial sink provide amount of carbon dioxide (CO2) and the combination of light energy for photosynthesis, symbiotic algae and plants to thrive and grow, fish or sea creatures or breathing or feeding on algae, energy transfer to the food chain and the formation of symbiosis. Conversely, if plants or algae lack light energy, they will die or die directly. Relative to the fish or sea creatures are not dependent, but also inevitably escape the fate of death, the integrity of the water or sea biological ecological cylinder that is unable to form. 2. Understanding of natural light sources and artificial light sources The light source of nature takes the suns light. So, whether land or sea creatures are light and with the participation of the food chain to survive and grow things. Similarly, the creation of a cylinder of water plants or marine biological cylinder, the inevitable lack of access to light energy. However, home aquarium tanks use natural light sources that are bound to be difficult. The light source cover and contain everything sunlight, scientists from the spectrum of the sun light precipitation except human eye can perceive visible light such as red, orange, yellow, green, blue, indigo, ultraviolet light is not the sun; with visible light infrared light, ultraviolet light, X light, laser light and other naked eye c
