I got my PC's tonight and added them to my NO tubes. I thought my tank looked good before, but now every soft coral I have has opened an extra 25% in only 4hrs under the PC's.
I have 330 watts of PC, less heat, less energy, more punch per watt, higher intensity, what more do you want, except for 400 watt metal halides I guess.
260 watts of pc..(2x65 50/50 & 2x65 10000k).......recently added 2x100 watt vho..(actinic blue).....maybe if I set-up a 220 in the future I'll reconsider mh/vho.......but for now I like the lighting on my 55 just fine
