My wife picked out this rock when I set up my tank a few weeks ago because she liked the yellow next to the purple rock. I liked it at first but then my curiosity kicked in and I became interested in what is actually on the rock.
Is it a sponge or something I should be concerned with? The LFS sold it to me so I assumed it was okay. Just newbie paranoia.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
