FYI-ATI has a new lamp out. Called: Coral Plus.
The latest in T5 bulb technology from ATI lighting, this is a great stand-alone bulb to stimulate coral growth. Its color spectrum falls between that of the Aquablue Special and the Blue Plus. This white lamp has a higher blue emphasis to enhance the fluorescent pigments in your corals while still having some peaks of red and green.
Yuppers I'm ordering one along with a couple of blue+
