I thought it looked like black beard algae but when I remove it from the water it is a beautiful blue green colour. So I wonder if it is blue green cyano bacteria.
What do you think? I want to figure what it is so I can solve the problem that is causing it as it os starting to kill of my beautiful crinun (plant).



And here is it without the black background, it
looks a lot more blue green from this angle.
