65 gallon AIO about 2 months post-cycle. Still have some "uglies" on the sandbed which I believe are likely diatoms as well as a few small patches on the rock.
Over the past 2-3 weeks this stuff has shown up as well. It's hairy and sticks to the walls/rocks but it isn't exactly green, more brown. Is it just a brown form of GHA?
