Looks like it could be. If you tank is less than a month old, then it is very likely to be diatoms(which aren't actually algae).

Check this out -

Sorry the pictures are crappy. I had to get to work but wanted to take a photo and I was in a hurry to get to the bar when I got home.

This was taken at 8 am as of lights on.

And at 6 pm - 10 hours later.

I've been doing water changes every day to get the NO3 and PO4 since I had bad test kits and get things in order. Just amazing how fast it grows in 10 hours.

That sure does look like a form of thread or brush algae... Something in your tank is out of spec. If i remember from the chat your co2 levels arent optimial.... concentrate on getting your dosing worked out and try to up the co2 level to @20ppm if not a little higher. I would probably also do a few big water changes on top of that...
