[labman]

I was moving some LR tonight getting readdy to add some more and ran
accross these on one of my peices of LR I never noticed it before but
it doesn't look good. if that is the case I might simply remove the
piece from the tank. there is also a slimie stuff that looks like
algee. #ed_op#br#ed_cl#

looks like a type of sponge, they are good not to worry :D

Agreed... a sponge. Leave it and let it help you filter water. Some sponges can be a pain in the butt if/when they cover zoas or other corals, but that happening is few and far in between. Otherwise, let it be.
