Changed bulb, hair algae

[likwid]

I have had my tank set up for over a year now and have never had a problem with hair algae. I recently changed my stock JBJ 150w 15 bulb to a Phoenix 150w 15k bulb and noticed a few days later that I had hair algae growing all over the sand and a bit on the rocks. Some of my corals weren't opening up to their full size either. It has been a few weeks now and the hair algae still won't go away even with all the water changes I am doing.

Does the new bulb have something to do with this?
