Some sort of red/dark purple algae has started growing in my tank, at the moment its just growing on the ornaments but i looks like it might be starting to spread to the plants?
What is it?
Is it harmful?
how and should i get rid of it?
any advice is greatly appreciated

p.s it looks like some weird sort of purple fur
