I currently use power compacts but was thinking of switching over to metal halides. Are the MH's the best way to go for reef? Will a 14K hqi bulb give a nice bluish tint? Current USA has a nice pendant 150W 14K HQI light for only $129. I was thinking of a couple of these to replace my 240W PC. It has 1 daylight bulb and 1 actinic. I am hoping that the 14K MH's will give a nice color in the tank. Any suggestions?
