You had to go and confuse me didn't ya Steve. : )  Ok, maybe you could make this simple for me.  The light sytem I am talking about is the coralife 36" 192W PC strip.  My tank dimensions are 36" x 16" x 20" (i think... the 16" is only in the middle...on account of being a bowfront).  What I am really interested in is whether or not I have enough intensity to keep anything more than shrooms and softies...  Is this enough info to give me a rough answer or is there more that needs to be considered...
