Is this coralline algae beginning to grow? I added the algae in a bottle 9 months ago not knowing it wouldn’t grow due to my nitrate levels but now my tank levels are perfect and I think it’s starting to grow.
Also have some white spider web looking stuff growing on a few rocks. Not sure if it’s a sponge or what.
