CMC Frag Plugs

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.

Standard Compatibility

Disc Size: ~1” (standard frag plug size)
Compatible with most frag racks and holders
Optimized for best performance within the CMC Breakaway System

Complete Your Setup

For best results, pair these plugs with the full CMC system:

• CMC Modular Frag Grow-Out System — for controlled placement and grow-out
• CMC Modular Hex Plate Refill Packs — to keep your system running as you cycle through frags

Designed to work together for a more stable, consistent grow-out process.

Pack Sizes Available

• 10 Pack
• 20 Pack
• 30 Pack

Uses

• Coral propagation
• Grow-out systems
• Frag swaps and transfers
• Replacement plugs for existing setups

What’s Included / Important Notes

• Current version is designed as a standard frag plug. It is not optimized for use with a standard coral saw diamond blade. While cutting may be possible with sufficient time and patience, I cannot guarantee blade performance or longevity. A dedicated Coral Saw Friendly version is currently in development.

• CMC Frag Plugs (quantity based on selected pack size)
• Frag plugs only — breakaway inserts and base system sold separately
• Minor surface variations may occur due to the 3D printing process
• Rinse before placing in tank
