CaribSea LifeRock Assorted Natural Reef Rock for Aquariums – 40lb Box

CaribSea LifeRock Assorted is a premium, eco-friendly alternative to traditional live rock, designed to deliver the natural look and biological benefits of real reef rock without harming fragile ocean ecosystems. Each piece is constructed from real calcium carbonate and seeded with living, spore-based bacteria to help establish base biological filtration in marine and reef aquariums.

The assorted selection provides a mix of natural shapes and sizes, allowing for flexible and creative aquascaping. LifeRock closely mimics the texture, structure, and color of natural live rock, with surfaces engineered to support coralline algae growth and coral attachment. Color-matched to mature coralline algae, it offers a deep, established reef appearance straight out of the box.

Supplied as a 40lb (approx. 18kg) box, LifeRock Assorted is ideal for larger aquariums, full tank builds, or major rescapes. With no unwanted algae, no hitchhiking pests, and no long curing times, it provides a clean and sustainable solution while helping protect the world’s natural reef systems.
