I saw some Volcanic Lace Rock at my LFS this weekend and they said it is safe for saltwater tanks. So I went to my local rockery and picked some up real cheap. They told me to wash it off real good and they put it in boiling water for a few minutes to make sure it is sterile. Had anyone used this before in their reef tanks or do you know of any problems with using this kind of rock?
