Product details
Walt Smith Reef Rock 2.1 21kg Box is a bagged supply of dry reef rock designed for saltwater aquariums. It’s used to build aquascapes and add porous structure that can support beneficial microbial colonization over time. Because it is dry rock, it should be cured before it is placed into a display tank. Many aquarists also use pieces alongside established live rock to help a new setup look and mature faster.
Features:
- Dry reef rock for saltwater aquascaping
- Porous structure intended to support beneficial microbial growth over time
- Handmade pieces—shapes and coverage can vary within a box
- A surface coating may help the rock look more “established” compared with completely bare dry rock
- Best used after curing and during tank setup for cycling/maturation
- Can be mixed with established live rock to combine starting points
- Shipping heavy rock can result in breakage; broken pieces may be repairable with epoxy (not included)
