Frag Arch Rock – 16 Frag Plug Holes 

New Design: The Frag Arch Has Arrived!
Make a bold statement in your reef tank with this large, sandbed-friendly 16-hole frag arch — designed to blend seamlessly into your aquascape while giving your coral frags the space, flow, and height they need to thrive.

🔹 Natural Reef Structure
Molded and textured to mimic real reef rock. The arch shape adds depth, flow, and dimension to your scape — while offering a clean, natural alternative to plastic racks.

🔹 Reef-Safe & Durable
Handcrafted in the USA using a special polymer resin filled with calcium carbonate. Heavy enough to stay stable on the sandbed without shifting.

🔹 Bacteria-Friendly Surface
Porous texture provides added surface area that supports beneficial bacteria colonization, helping to maintain a balanced, healthy tank.

🔹 Custom Color Options
Available in Coralline Purple (pictured), Tan, or Black — or request a custom color to match your reef’s style.

🔹 Big Size, Big Impact
Measures approx. 14.5” x 4.5” x 6” — ideal as a central scape feature or large frag grow-out base.

Whether you're growing coral or just want to level up your aquascape, this Frag Arch brings together function, beauty, and realism — all in one standout piece.
