Product Description

These ceramic plugs look natural and are heavy. Unlike aragonite mixed with a Portland cement, do not leach aluminum. Plugs are designed to organize, trade and not detract from the beauty of your aquarium. We have provided a hole and a Tyvex tag, so that you can easily track and organize your coral plugs. Tags can be written on with sharpies or underwater with a dark pencil. The shape of the plug is designed to ensure water flow to the base of the fragment and to better blend in with your reef. Ceramic material instead of cement; curved top surface for better water flow to prevent RTN disease.
