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)
