Hi, sorry if this is in the wrong forum page, but i hold live rock in my tank, its full of greens maroon colours, but i have noticed a really interesting light brown, what seems to look like biscuit crumbs on my live rock all in one place together on one rock, my tests are ok, so i belive it is not any thing to worry about, just interested, so does any one know thanks:dunno:
