So in your opinion, what is the best bulb to use for a mixed reef??? I know there are alot, but if you could only use one, what would it be?? and why?

Depends on what wattage.

400w - Radium 20k Why? Proven Rich Color and Growth
XM- 20k

250w - Reeflux 12k Proven Color and Growth
Giesemann Coral 13k

175w- Iwaski 15k Par Monster rivals many 250w

I've only used the reeflux 400 watt 12 K bulbs but in 6 months, I've had nice growth on SPS & soft corals and very nice color.
