It is a Cyano
Also known as red slime algae .
Cause is , high nitrates , phosphates ,
What are you using for water ?
Even though you are testing 0ppm for phosphates there are phosphates in there .
I had the same problem before switching to RODI
As soon as I switched and added rowaphos to my canister for a media it was gone instantly .
Phosphates soak into the rocks and over time they will not be detectable .
How often do you do water changes ?
I had a urchin and it worked amazing on algae .
It was more into the coralline algae , and hard algae on the glass .
They don't do well with nitrates and makes their quills fall out .
