    I agree.
    Hard as rock but can be scratched off: coraline algae
    Soft and slimy: cyano bacteria
    Neither: angaas?

    Cyano.
    Can siphon it off on your next waterchange. But it will come back.

    Difficult to id from pics. If it disintegrates and gets broken up by flow, cyano, but I think this is something else.
    Could be Peyssonnelia, in which case, lets hope it grows into its glorious table top shapes if it is...
