CaribSea LifeRock Reef Tree Extension Kit – Modular Reef Expansion Rock

Enhance your existing reef tree aquascape with the CaribSea LifeRock Reef Tree Extension Kit, a purpose-built expansion set designed to add height, arches, and visual interest without drilling, hammering, or using adhesives. This extension kit allows aquarists to effortlessly upgrade their reef structure while maintaining strength and stability.

The kit includes two hand-crafted, naturally arched LifeRock pieces with unique shapes, each pre-drilled to accept the included stabilizing support rod. Made from natural base rock composed of 97% calcium carbonate and enriched with trace elements such as strontium and magnesium, LifeRock maintains excellent porosity through layered engineered aragonite coatings. Infused with beneficial bacteria using AragAlive™ technology, it helps jump-start biological filtration and delivers the appearance of a mature reef from day one—with no curing required and no unwanted pests or hitchhikers.
