Coral and Invertebrates

Lighting: Vivid Aquariums uses 14K Ushio bulbs. Kelvin rating measures the color and intensity of the bulb. The higher the K, the more blue the light. The lower the K, the more yellow. 10K is white light. 14K is bluer. And 20K is bluest. 10K (white light) is best for fastest coral growth but not color. 20K (blue light) is best for color but not for growth. We recommend 14K for coral growth and color.
