Real Reef Original Rock – Extra Large (3–5 pcs, 10–15 lb each)

This 50-pound box of Extra Large Real Reef Original Rock contains 3 to 5 massive pieces, each weighing between 10 and 15 pounds—ideal for dramatic centerpiece structures, large reef foundations, or show-tank aquascapes that demand scale and presence.

Each rock features the signature Real Reef look, with vibrant shades of purple, pink, and red that replicate mature, coralline-covered live rock—without the risk of pests or hitchhikers. Despite their size, the rocks remain lightweight and porous, providing excellent biological filtration and multiple aquascaping possibilities.

Crafted from eco-friendly, reef-safe materials and cultivated in greenhouse environments, these bio-active rocks are aquarium-ready for reef or fish-only saltwater systems. Not intended for freshwater use due to their natural pH-buffering properties.
