Caribsea LifeRock Frag Zone 2lb (≈1kg)

Caribsea LifeRock Frag Zone is a purpose-designed aquascaping solution created specifically for coral frag placement and growth. Manufactured from real aragonitic rock and infused with shelf-stable spored bacteria, Frag Zone provides immediate biological filtration while offering flat, stable surfaces ideal for mounting coral frags, plugs, and small colonies.

Unlike traditional live rock, LifeRock Frag Zone is ready to use straight from the box with no curing required and no risk of pests, nuisance algae, or unwanted hitchhikers. Its textured surface and natural reef coloration encourage coralline algae growth, helping your frag area blend seamlessly into the rest of your reefscape.
