Algae ID please

[JustaSunday]

I had/have been battling dinos in my 20g long for months now. Recently I thought I had had a break through when most of my rock work appeared to clear up with only some tufts of gha left. The sand on the other hand seems to be shifting back and forth. At first it was mostly dinos, then perhaps diatoms and now I have something that even with my blues turned off or down appears strongly redish brown, more so than the dinos and diatoms did at any rate. In the picture I specifically made sure to include my blasto so the reds could be compared for refrence. Im starting to think that Instead of dinos I have cyano now... any help or thoughts would be great!

Yeah, it does appear to be cyano, but I would want a more experienced person to confirm. This isn’t too bad of an algae to deal with though thankfully, at least when I’ve had it.

If it is cyano I would honestly be relieved haha

Bump for any guessers (can also take new pictures as it hasn't gone away)

It does resemble cyano starting imo

Photos under white lights? My guess is cyano as well

Here’s a picture under more whites of the same spot as well as a separate spot where I have something a little more brown growing



Hopefully the mobile upload does not compress the images

For anyone who stumbles upon this post, I ended up doing a peroxide test on the red stuff where I took a small amount out and let it sit in small container with roughly 80%salt water and 20% 3%H202. Turns out I had a red cyano and not red spirulina since in the sample the cyano turned green and stained the water pinkish. Treatment for the tank has included manual removal and dosing 2ml h2o2 in the morning before lights on and again right after lights off. So far I do not see it spreading anymore and is mostly gone.
