CMC Frag Plugs – | Cox Marine Creations

Designed for real-world reef tanks where consistency and stability matter.

CMC Frag Plugs are designed to work seamlessly with the CMC Modular Frag Grow-Out System, providing a secure, stable foundation for coral frags during grow-out and transfer.

Unlike standard loose-fitting plugs, these are tuned for a tighter fit—helping reduce movement, wobble, and stress on sensitive corals.

Key Features

• Optimized for use with the CMC Breakaway System
• Tighter fit reduces frag movement and wobble
• Stable base for sensitive and growing corals
• Compatible with most standard frag racks
• Reef-safe PETG construction

Optimized Fit

These plugs are specifically designed to:

• Sit securely inside CMC breakaway inserts
• Minimize shifting during water flow
• Provide consistent stability during grow-out

Standalone Use

CMC Frag Plugs can also be used independently in standard frag racks and systems, just like traditional frag plugs.
