I ordered the Dual 400w 20k Radium on PFO HQI ballasts. I actualy met up with a reefer around my area who is using a single 400w 20k (HQI ballast) Radium on a 40g breeder...his corals look great! The color of the bulb on the HQI ballast isn't super blue at all...more like a nice ice blue, looks really good though...alot more natural looking then my "operating room" look 10k's.
Can't wait to set this tank up!
