Cyano confirmation?

[Staindsoul]

Nutrients were too low for too long, I think. No3 5ppm
Po4 .003 for a couple months then dipped to undetectable

+ I'm at 5 month mark for the tank, so I'm sure that's adding to this being an ugly phase.

Stopped skimming and skipped a water change. Been siphoning this red junk out every other day. Mats on the sand, stringy, and bubbles of air.

N03 is at 10ppm
Po4 is back to .003ppm

Dosing vibrant, ocean magik, and siphoning what I can. Started a 3 day blackout this evening.

This is cyano correct?

Thanks in advance!
