What is this?

I've been letting it go because I thought it looked cool and didn't want to do anything to my coraline algae that has been spreading fast.

But I figure I should have these identified.

2 different brown kinds.

1 is like a stalk
The other is like short hair tufts.

The first one looks like diatoms

Or really? Hmmm, I've only had dusty ones. At least the flow they are doing looks cool and the blenny is chowing down
