It seems to have the name Green Dust, GD.

I have seen this algae, Mr. Rubin please stand up, in well run tanks that
are mature. I was able to induce it from his tank to mine about a few months
ago. It persisted for about 3 weeks. It's appearance is annoying but doesn't
damage plants, is a sign that the plants are doing well generally and that
you have plenty of light. Much better than Green water, BBA etc and easier

Both. Try www.liteman.com
The Flourish stuff will get you through just fine.
The reason why I suggested using a UV or a micron/diatom filter is after you
scrape off the algae, it will pick it up and kill/remove it. The water
change and vacuuming also removes the settled algae.
Once your plant's roots get well established and the plant get going better
you'll very likely not see this algae afterwards. Just keep after it. The
beginning stages are rough for most tanks. Expect work and extra cleanings.
Try pulling the light back from the front of the glass also.
I have not be able to work on what makes this algae tick but it did not last
and I found no nutrient correlation to it's presence or absence. It did seem
to grow fast a day or two after a nutrient or a water change was done. I
scraped it off every 2-3 days and kept up on the nutrients. Harass it back.
Some fish that might help are bushy nose plecos. Blackout also seemed to
really be effective also.
