Real Reef Original - Boxed Rock
The foundation of any Real Reef aquascape. Real Reef Original Rock is the standard, eco-friendly aquacultured (man-made) reef rock, a versatile mix of natural shapes full of holes, crevices, and shelves for building any reef structure. Cultivated in greenhouses instead of harvested from the ocean, it is lightweight, extremely porous, and colored in natural purples, pinks, and reds, with none of the pests or contaminants of wild live rock. Choose a mixed box by weight, or a 50 lb box graded to the piece size you want for precise aquascaping.
Pair it with the rest of our saltwater supplies and hardscape.

Aquascaping tips
- Dry-fit your layout first, then bond pieces into stable structures with cyanoacrylate gel and reef-safe epoxy putty.
- Leave open space and flow around the rock for coral placement and easy maintenance.
- Rinse before adding, then cycle the tank so the rock becomes fully bio-active.
