nope, not cyano. My whole tank is covered in it and I've dealt with it for a while. Different structure from cyano, both by sight and touch. In my tank it was/is dinos or growing with dinos. Very snotty and slimey. If you blast it with a baster, it just puffs off the surface, unlike cyano which tends to peel off in small chunks or sheets.

The second round o fit recently killed off all 60 snails in my tank, further reinforcing the dinolagellate theory...
