Is this coralline algae starts or does cyano stain?

[Cinnimin]

I just vacuumed up a lot of my cyano (presumed to be from lack of circulation which I now have a powerhead to fix) and found a BUNCH of these pink spots under the algae. My shells that were carrying some coralline before going into my tank have over tripled the coralline by now and even my new Mexican turbo snail has a lot more and its just been in my tank like 3 weeks. I however had thought the first bit of red on my rock was coralline and it was in fact a bright red cyano. (Ps. My shroom is angry, he has been moved around a lot today as his initial movement angered my hermits)

Looks like the start of coralline algae to me.

+1 to coralline.

I think this would be my most exciting stage when starting a tank or when restarting a tank with new rocks. It never gets old no matter how many times you been through it. That redish, pinkish, and greenish stain spots on the rocks that you just can't get off. It means you gonna have an epic tank!

I’ll vote for cyano based on seeing the same color on the sand.

take a small toothbrush to it, lightly. It comes off, cyano, stays then coralline!

Time will tell.
+1 to the thrill of starting a new tank
