Hi, I ordered a box of live rock. When I opened it I noticed one of the heat packs had broken and got on some of the rock. It was hard to get all of it off the rock and all nooks and crannies. So some of the stuff is still on the rock. I have the rock sitting in a garbage can with saltwater. Is it ok to keep the little bit in there with the water or will it leach something into the water? Any help would be appreciated.
