replace light bulb induces cynobaterica??

[mandarin man]

The cyno is getting worse today, a little patches every where and I am not happy at all. I have to do major clean up this weekend when doing water change.

I just recalled, before changing the light bulbs, I took out the ceramic bio and added in like 10pounds of uncured live rock. Is this the reason for the algae bloom? Need your input on this one...
