Seachem Aquarium accessories Coral Plugs (x12)

Safe base for freshly cut corals and polyps. Contains sources of calcium and magnesium for rapid growth. The unique shape encourages coral or polyp proliferation. They are enriched with calcium and magnesium to help corals grow quickly and safely. They are designed for mounting SPS and LPS corals, but are equally suitable for soft corals, colonial polyps, and various other sessile invertebrates. They are also designed to tightly bond when used in most coral cultivation systems so that various encrusting and colonial corals, such as zoanthids, can quickly spread from one plug to another.
