ID this thing for me please.
Are they bubble algae? They start out really small and get to about 2-3cm diameter. As they get bigger they get sort of an irridescent sheen on them. They can be good or bad. I kinda like 'em but I've never had them in epidemic proportions. Maybe try to post a pic if this isn't it.
