Hard to tell but looks like Corraline to me. If your unsure just take a turkey baster or powerhead and try and blow it off the rock. Cyano will just come right off.
Pointed a powerhead right at it and it didn't budge! Was pretty sure it looked like corraline, thanks for confirming. Looks like my seeding is starting to take hold (yeay!).
