Is this the start of a cyano bloom or is this something else??

Need input!!

This is what I am seeing the last few days... Red patches on rock work and bubbles. That is what is throwing me off. Can anyone ID what this is? Thank you

If you can blow it off the rocks with a turkey baster, then it is most likely cyano. What about when the lights are off , does it seem to disappear?

Just regular algae to me with some photosynthesis bubbles on it.
