Diatoms or something else?

Tank is a month or so old. Had a very mild diatom outbreak a week or so ago and it died. Now this. I thought it was diatoms again based on color, etc. But it looks filamentous growing up the glass. I thought diatoms would form an even layer. It also grows very, very fast. I had some people coming over for dinner so I quickly moved some gravel over it. By the time they left it was growing back.

Not diatoms. Some type of filamentous algae probably. Considering that it's only a month old, I'd like to be the first to welcome you to the Uglies!

You can take a Magic eraser sponge (original, non scented) and wipe it away. Reduce white light intensity a little also.

Thanks so much! It's good be part of the club. It's like when an old girlfried broke up with me and said, "welcome to celibacy!"
