Cyano and Lights

Hi all,

I recently (1 month ago) changed my lighting setup and have noticed an increase in cyanobacteria and hair algae ever since. I have a 58 gal tank with LR, a bunch of Xenia, two mushrooms, and some zoanthids. Originally I had one 400W 20k MH running 8 hours per day. Thinking this excessive, I added two 24W 50/50 PC lights and cut back the 400W. Now I run the PCs for 4 hours, then the MH for 4 hours, then the PCs again for 2 hours.

Did the changing of the light contribute to the increase in cyano? Does the decrease in powerful blue light favor cyano over other, more attractive forms of algae? Or is this just a coincidence?

Thanks for any thoughts.
