CMC Modular Hex Frag Grow-Out System | Cox Marine Creations

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

The CMC Modular Frag Grow-Out System is designed for controlled coral growth, secure containment, and easy frag removal—providing a complete solution for growing and managing coral frags without sacrificing flow.

The low-profile design sits flush with the sand bed while maintaining consistent flow around the frag and keeping it stable and contained.

Key Features

• Complete all-in-one grow-out system
• Modular hex plate design for easy frag separation
• Open structure for consistent water flow
• Low-profile sand bed placement
• Reef-safe PETG construction

Complete System Design

Each unit includes:

• A stable stand for placement
• A frag plug
• A modular hex plate platform for controlled growth

Everything is designed to work together as a single, complete grow-out system.

Modular Hex Plate Design

The hex-shaped sections are designed to be easily separated once the coral has grown out.

Each section can be:

✔ Glued directly in place within your tank
✔ Mounted to a new frag plug for placement or sale

This allows you to grow, separate, and reposition frags without disturbing the main colony.

Designed for a Secure Fit

The system is tuned to provide a stable, reliable hold for standard frag plugs while maintaining proper flow and minimizing movement during grow-out.

Compatibility

Platform diameter: ~24 mm
Plug socket opening: ~10.5 mm
Compatible peg size: ~9.5 – 10.2 mm

✔ Fits most standard frag plug sizes
✔ Designed for stable, real-world use

• CMC Modular Hex Plate Refill Packs — refresh the system as you cycle frags
• CMC Frag Plugs (CMC Fit) — for a tighter, more stable fit when mounting new frags

Designed to work together for a cleaner, more controlled grow-out process.
