algae id

I have this very fine, fuzzy-like stuff that covers the frag plugs in my coral QT...it is also on the 2 live rocks that i have in that tank as well. In the pic, I can see a few air bubbles. I've been battling diatoms regularly in this tank, but those are receding quite a bit. I can't keep...
