Firstly, please disregard the cyano. Been battling it for a while and it's getting better.
Second, what in the heck is this stuff? It's dark green strands, maybe 1/8" in diameter. Dark green, but some strands have a bright green center. There's more of it elsewhere, but this is the biggest piece.
For reference, this chunk of rock was purchased from my lfs, already aged with coralline, spent some time in my DT, and is now sitting in a large plastic bin with a bunch of other rock and an eel. Showed up soon after the cyano started going away.
