CaribSea Life Rock Branches-Seeded with Bacteria, Sponge and Pods *price per pound!*

CaribSea LifeRock Branch combines aragonitic base rock with millions of micro and macro pores to establish beneficial bacteria colonies and support biological filtration. Pre-seeded with spored bacteria, sponges, and pods, it jumpstarts a mature reef ecosystem while remaining 100% safe for fish, invertebrates, and corals. The textured surface mimics natural coralline algae and encourages live growth over time. An environmentally responsible alternative to cement-based rocks, each piece is uniquely shaped for dynamic aquascaping.
