Real Reef Large Arches – 30 lb Box (4 pieces, ~14 inches)

Real Reef Large Arches deliver bold, reef-safe calcium-based structures that bring dramatic natural forms to your aquascape. This 30-pound box contains 4 pre-cured arches, each approximately 14 inches long, featuring vibrant pink, purple, and red hues that replicate mature coralline-encrusted rock.

Perfect for creating striking overhangs, caves, swim-throughs, and elevated coral platforms, these arches are designed to enhance water flow, fish behavior, and coral placement. Their lightweight, porous design supports biological filtration while providing a stable, functional framework for your reef.

Safe for marine reef and fish-only saltwater aquariums, Real Reef Large Arches also work well in hard freshwater systems with higher pH. Sustainable, pest-free, and easy to work with, these arches make a powerful centerpiece or support structure for any reef setup.
