Oceans Wonders Ceramic Coral Frag Plugs are 100% reef safe and are fired at nearly 2000 degrees making them completely inert. Ceramic frag plugs do not need to be cured and can be used right away.
Black frag plugs are ideal for blending into frag racks that are commonly used at frag swaps and shows. The color also helps with taking pictures and color balancing since the black color will not be affected like a white plug would.
