I fitted some new 150w Phoenix 14k HQI's about a month ago & had the same thing.
My tank looked like a monochromatic wash of blue.
For me this lasted about 2 weeks & now it look's slightly bluer than my previous 14k bulbs.
The only thing I don't like is that they seem to have slightly less PAR than my old Current USA ones.
Give it a few weeks to see if they improve.
