Been a while since I last posted. Had a tank infestation with vermited snails Lao started a new tank. Currently in a fallow period but I have a few corals still in the tank.
However, during this fallow period I’ve noticed stuff growing on the back glass of my display and in the first chamber of my sump.
Can anyone tell me what these are please?? Only seem to have started growing since I have gone fallow.
Many thanks in advance
