Tank is about 2 months old, been cycled for 5 weeks. Just finished the worse part of my diatom bloom and now this DARK maroon color algae has shown up, it looks purple in the pic. I'm almost 100% sure but I'd like a second, or 100th, opinion. Right not it looks and has the length of hair algae but purple in color.
