The Reef Disc is Boston Aqua Farm's design, conceived over 4 years ago and marketed for almost 4 years. None of the copies can touch their quality or consistency.
Ceramic Discs are just like their popular aragocrete Reef Discs, made from a ceramic material.
Boston Aqua Farms coral cermaic discs are specially designed to take advantage of all the best qualities of other plugs and coral frag mounting solutions to date.
Discs are designed primarily to support Acropora, Montipora Digitata and other thin branchy species of coral.
Many will have a small divit at the top, to hold a pool of glue where your frag can rest.
Ceramic plugs require no curing and will not leach anything into your water
