Algae indentification

[tocan]

I have had brown algae or diatoms growing on my glass for some time now. I can wipe it off with just rubbing lightly. But know I have bright green algea that wont come of without a good fight. I have to do alot of scrapping in the same spot to leave a mark. Good or bad? I have a 24g nano with a sunpod 150 hqi with a 14k bulb. I put live rock in about a month ago. It seamed to start after adding calcium.
