Plucked out a few yellowing spirodela polyrhiza. I think I took too much of this out of the tank last week- four handfuls. It didn't multiply enough to entirely cover the surface again yet, and for some reason stays clear of the area just above the big anubias. One anubias leaf had a lot of brown algae accumulating. Easy enough to wipe off, but I want to prevent that.
