So ive had cyano for almost the entire life of the tank... it dosen't bother me very much because it usually stays undercontrol. But just lately it has started to get stringy and annoy my corals as you can see in the corals. Is this cyano or is it some other type of algea?

and i do suck it out... i have read quite a bit on how to get rid of it, I'm more just trying to make sure cyano is what this is
