Earlier this year, a study led by Dr. Tim Wijgerde concluded red light actively represses chlorophyll a and zooxanthellae growth in Stylophora pistillata whereas blue light appears to do the exact opposite.

Dana Riddle also continued his research on how corals and their zooxanthellae responded to differing spectral qualities and photosynthetic efficiencies.

Now a new study shows how light quality shapes coral skeletal development.

In short, researchers compared the skeletal growth patterns for clones (aka frags) of Acropora formosa and Stylophora pistillata grown under blue T5 bulb, blue LED, and full spectrum LEP (plasma) lighting systems with comparable PAR values of 250
