Algae HELP!

[downhill_biker]

I am unsure of what kind of algae this is, but I am having some issues with it. I need to figure out what it is, and why it is growing in this frag tank, and not the other, and why it isn't growing in the display or sump, since they are all connected on the same system. I set up this tank 2 weeks ago and it is getting out of hand.

I'd say its the white eggcrate, for some reason they always grow hair like that!
