Reef Plugs (Bag of 20) | Boston Aqua Farms
The Top of Boston Aqua Farms' Reef Plug is about 1" in daimeter. The peg of the reef plug is designed to fit nicely into eggcrate, it will also fit nicely into a small crevice or hole in your live rock. (Some drill 3/8" - 1/2" holes throughout their new live rock, to provide future resting places for our frag plugs.)
Reef Plugs are designed primarily to support Acropora, Montipora Digitata and other SPS corals but work great for other corals such as zoanthids.
Ceramic plugs require no curing and will not leach anything into your water
