Thrive’s take on the common coral plug is anything but common.  These ceramic plugs look natural and are heavy.  Unlike aragonite mixed with a portland cement  Thrive’s Coral Plugs 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 ensured water flow to the base of the fragment, and better blend in with your reef.

Available in Small and Medium sizes.
