Thanks Lynn! For the time being it seems like the only algae that wants to grow is that blasted bubble algae. However, I am noticing some small spots of coralline algae growing on the glass near the back. That happened in the 50-gallon, too; most of the back wall was covered in coralline. I think the purple algae on the black background will give the tank a nice goth look. Maybe I'll name my next fish Siouxsie Sioux and Robert Smith.
