FAQ: Is Seachem Reef Glue™ toxic to my fish, invertebrates, bacteria, or corals?

No, Reef glue™ is safe to use in a reef system, even with delicate invertebrates or corals.  It is, however, still glue.  If your fish or invertebrates attempt to eat the glue before it has set, it is possible for the glue to stick to their mouth or teeth.  It is recommended to keep fish away from the glue until it has fully set.
