I personally love the look of a 20k radium. I agree with pappy, really? That pic doesn't look right to me. I personally run LEDs in more of a 16-20 look. Love it, nice n crisp.
Also in the 20k fan club. I have my Radions in 14k, and 18k for a few hours while at work. The 20k starts when i get off work and get to view the tank.
