CaribSea LifeRock Small Natural Reef Rock for Marine Aquariums – 20lb Box

CaribSea LifeRock Small is an eco-friendly alternative to traditional live rock, offering the natural look and biological benefits of real reef rock without damaging ocean ecosystems. Each piece is made from real calcium carbonate and seeded with living, spore-based bacteria, ready to support base biological filtration in marine and reef aquariums.

The rock features realistic shapes, textures, and colors that closely resemble natural live rock. Its carefully engineered surface allows coralline algae to spread and corals to attach and grow naturally, just as they would on ocean-harvested rock. Color-matched to mature coralline algae, LifeRock delivers a deep, established reef appearance straight out of the box.
