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.
Coralline Purple frag plugs are colored to match real coralline algae that will grow in your reef aquarium. Unlike traditional white frag plugs that stick out like a sore thumb, the purple coloration lets you camouflage the plug much easier.

Not as good as I had hoped By Randall on 8/8/2017Randall wouldn't recommend this product to a friendThese frag plugs have a nice coralline purple color, but it's just on the surface. If you want to chip off some margins to give the plug a more natural irregular look, those spots will be bright white, at least at first until actual algae grows on it. Would be a nicer product if the color went all the way through.
