I'm new to this site so I would like to get a feel for what everyone is using for lighting. I have a 120gal with a 75gal for a sump in my ceilar. My tank consists mainly of sps corals and other rare things that can withstand alot of light. I use 2 400w 6500k iwasaki's, and 4 110w vho's. Three vho's are uri aquasun's and one superactinic from uri.
