This isn't really an algae that I've come across before. It's these little green circles of algae that have planted themselves along the glass. When I took a stranded algae remover it didn't do anything. I used to fingernail to scratch of a few but they are tough. How do I remove them? Also pics to see what it is if you can see it.
