Can someone please help identify this red algea

[thaddo]

I need help figuring out what this red algea is. It comes back after I suck it out with water change.

100% correct statements above, it is cyanobacteria. there are several commercial treatments available but primary to treating to kill the cyano is reconsidering nutrient export or flow parameters to prevent its recurrence.
