Brown algae ID? Are these possibly dinos or diatoms???

[Madonia]

Can someone help me identify this algae?

tank was set up 9/5/20. I used dr Tim’s as well as microbacter start.

I had a bad outbreak of cyano recently and used chemi clean which helped my rocks and sand tremendously.
Now 4 days later this brown algae is all over the rocks and back of the sand bed.

I have my lights cranked up with white so you can see it more clearly.

many tips are appreciated

last I checked my nitrates were 1ppm and my phosphate was 0.05ppm.

Since C-Clean killed off most of your good stuff as well as bad its prob some form of cyano that it didnt kill. Cyano is usually the first to come back.
