Help ID this algae

[TracyLynn]

Hey team, I posted this on the nuisance algae forum & since I added microscope pics no one has chimed in. All the pictures I can find online don’t really match my pics. Here is my original post with the pictures.

Is this normal after using Vibrant?

2nd dose of Vibrant used on Monday 3/16/20. Is this normal to see this covering my sand bed after the 2nd dose? I’ve ran both of these tests posted here to check if it’s Cyano or Dinos...

Thanks so much!

Its hard to tell what it is. How far apart were your Vibrant doses?
