Hi All, Do I have to tie it to a brick or what? I have it held down for the moment. Will all the bubbles come out and then it will lay there and play nice? Also, it doesn¹t matter how big the piece is right? It doesn't give off minerals rather it waits for the shrimp to come over and eat it, right? Thanks Shango _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
