The white one is for the corals, the blue is for you...it helps bring out the oranges and greens and such.
If you are going to try to keep anemones then you really should go with MH's or T-5's on an IC 660 with individual reflectors but I think the smallest they go is 24 inches so the MH is about your only option and nems dont usually do very well with PC lighting
Actually I'm a newbie when it comes to this, I've only been at it about 7 months. I just read, and read, and read. I participate in forums like this to get knowledge from others and I joined a local reef club as well. This hobby can be very addictive but it keeps me out of trouble. Sorta.Grins my friend you must be one cool person to hang out with and talk fish and such all night. You seem to have good knowledge of saltwater. Been doing this awhile huh.
