Red stuff on rock?

[Daddyrawg]

Is this cyano or red algae or coraline on the rock behind the pulsing xenias? I dose nopox 4ml a day on my 90..

Looks kinda fuzzy in the pic I see, coraline is hard and somewhat smooth.
If you can blow it off the rock its cyano, if it's hard to scrub off its red hair.
My guess is red hair algae, Mexican turbos can remove this in days.

Then again, maybe it's just what I see in the pics

If its cyano should I stop nopox?

Nope..

Siphon it out.. Turn off lights for 3 days.. Repeat as needed every couple weeks.
