Confirming this is cyano...?

Hi, I added Chemiclean to my tank a couple days ago (coming up on 48 hours) and just took the video below. I was expecting more to be gone by now (carefully followed all instructions) but wanted to be sure that red stringy slimy stuff is in fact cyano before I try another dose. Thanks!
