Sounds like Cyanobacteria. The black out method should work well. First, remove as much of the alage by hand as you can, then wrap your tank with some blankets for a few days, no food, no light, no nothing. Just let it sit. Do about a 30 - 40 percet water change before and after. You should see it dissapear soon after.

Sounds like the Cyanobacteria to me too. I just finished a battle with this stuff that lasted 6 months.

The guy at the lfs sold me a chemical called CHEMI-CLEAN made by Boyd Enterprises INC. It is sold for salt water tanks but works just as well in freshwater.
It took 4 treatments (one treatment every 48 hours) to kill the Bluegreen variety in my tank. Put floss in your filters. after a few days you will see the filters gather the dieing Cyano. Rinse the floss out every few days to get rid of the stuff. 48 hours after the 4th treatment I scrapped the glass clean. Waited an hour for the junk to settle out then did a 50% water change. Really vaccumed the gravel well. Used the change water to scrub the plastic plants and rocks. You must clean the filters as well. Put new media in. When you fill the filters with media be sure to use Carbon or Charcoal. The lfs guy said that maybe something in my water caused this and to use carbon to purify the water. In the past I never used the stuff.
This was 3 weeks ago and there is no sign of the bluegreen junk coming back.

hope this can be of help to people battling this gunk.
