And if it is not present in the soil, what can affect the corals separately? How can we help them?

A slightly stronger current is needed.

As a preventive measure, you can brush it off, place it a bit in the shade. Once, my Papua corals were affected, just one of them, without any obvious reasons. It didn't want to open at all. First, I brushed it, then I vacuumed it, moved it slightly into the shade, and by the way, there was more current there (40 cm from the 2700 Aquael). After a week of "vacuuming" and other procedures, the Papua coral became like new.

The idea that cyanobacteria don't like current is a myth. I don't have much experience, and my aquarium is quite new, but my cyanobacteria actually grow in the area with the strongest current. What can I say, the water pump is completely covered in it.
