Description
Real Reef Medium Arches – 20 lb Box (4 pieces, 10–12 inches)
Real Reef Medium Arches provide durable, reef-safe calcium-based structures perfect for building naturalistic aquascapes. This 20-pound box includes 4 pre-cured arches, each measuring between 10 and 12 inches, featuring vibrant shades of pink, purple, and red that authentically mimic mature coralline-encrusted rock.
Ideal for creating impressive overhangs, swim-throughs, caves, and elevated coral platforms, these arches simplify aquascaping for aquarists of all skill levels. Their lightweight, porous design promotes biological filtration, enhances water flow, and supports coral placement.
Safe for marine reef and fish-only saltwater aquariums, these Medium Arches can also be used in hard freshwater systems where a higher pH is acceptable. Sustainable, pest-free, and easy to work with, they serve as stunning centerpieces or structural supports in your reef environment.
