AF Plug Rocks

AF Plug Rocks are small, porous stone plugs designed for mounting coral frags. They mimic natural live rock in texture and appearance, so once placed in your tank they blend in well and quickly get covered with coralline algae and other beneficial growth. Their porous structure also provides extra surface area for helpful bacteria, supporting biological filtration. Each plug has a standard stem size that fits most frag racks and holders, making them easy to use in both fragging setups and display tanks. They’re reef-safe, lightweight, and a great option for securely growing out coral frags before transferring them to the main rockwork.
