Hello all, I have new-ish setup, about a month and a half in after moving up from my 30g. Currently going through a diatom bloom along with some sporadic GHA. I saw these little feathery things on the glass and they cleaned off quite easily, but then they started popping up all over the rock. They have a green-ish base and white feathery looking things sticking out. Any ideas? Thanks in advance!
