I had the same stuff that is in the second picture (the hard grasslike stuff) on some live rock that I got when I 1st set up my tank, then I got a turbo snail and he cleaned about 3inch x 5 inch area within a week, it's never came back, don't know if it was a fluke or what but he sure seemed to like it a lot.
