What kind of light do corals need?
The blue spectrum, not white, is what corals need for optimal growth. It helps stimulate reef calcification, the main measure of growth. In the process, coral lays the foundation for its calcium-rich skeleton.

According to one study, blue light also helps increase the abundance of zooxanthellae in corals. It also helps increase chlorophyll A levels in these algae.

On the one hand, chlorophyll A can only absorb wavelengths from 440 nm to 675 nm. The shorter wavelengths of blue light are only 450 to 495 nm. In fact, it is perfect for the photosynthetic needs of Chlorophyll A.

Blue light doesn't just boost coral growth, though. It can also help affect the pigmentation of corals as it promotes the production of chromoproteins.

These give coral its signature hue. That's why when you use blue light in a Fish Tank, you see fluorescent colors that you don't see in traditional full-spectrum lighting.
