I have 2x65 watt actnic blue and 2x65 12000k PC, can someone tell me what the 12000 and what its good for and what combination of PC bulbs would be best for a reef tank? I dont understand all this and need someone to explain it to me. Right now my tank has a slight blue color to it not the really clean white light i see at fish stores or is what i have better?
