## Overview

CaribSea Original Life Rock Medium is a 4-pound, dry aragonitic rock mined inland to ensure no harm to aquatic environments. Pre-seeded with live spored bacteria, it accelerates aquarium cycling while providing natural filtration. Its realistic coraline coloring enhances reef tank aesthetics without the need for curing or risk of hitchhikers, making it the perfect eco-friendly base for a thriving, natural-looking marine habitat.

## Description

Real aragonitic base rock with live spored bacteria, shipped dry.

Review: Great value - Excellent! Flat on 2 sides. Great peninsula rock for my 14g nano tank.
Review: Good rock - They could package this better, as just plastic wrapping the rock lets it get damaged very easily. The damaged spots show up very obviously as the purple coloring gets removed from it. But overall it's a very nice dry Rock. Some dust, and size is larger than expected.

Excellent! Flat on 2 sides. Great peninsula rock for my 14g nano tank.

### ⭐⭐⭐⭐ Good rock
*by J***N on November 23, 2024*

They could package this better, as just plastic wrapping the rock lets it get damaged very easily. The damaged spots show up very obviously as the purple coloring gets removed from it. But overall it's a very nice dry Rock. Some dust, and size is larger than expected.

### ⭐⭐⭐ Expensive
*by N***K on April 23, 2026*

Good size, good looking and porous material, but gosh why a stone should cost 30+ dollars ?
