I re-read this thread and now kind of wish I had more spectrum. Good thing yesterday I went ahead and bought a couple red, cyan and a couple more cool whites =-) Not really sure why as I am still only on 25 percent of my power as is.... I think I just want too. I couldn't say anything MORE positive about having the spectrum. I am ESPECIALLY noticing the greens, pinks, reds, whites, neons and purples more. Not to mention the corals color seems "sharper"
