CaribSea LifeRock Donuts 4Pk – Reef Swim-Through Aquascaping Rock

Create eye-catching swim-throughs and coral platforms with CaribSea LifeRock Donuts 4Pk, an environmentally responsible reef rock that delivers the natural look and biological benefits of live rock. Crafted from real aragonitic rock, LifeRock features extensive macro and micro porosity and is infused with spored beneficial bacteria to support efficient biological filtration from day one.

LifeRock Donuts are designed to form instant caves, swim-through spaces, and large coral seating areas that look completely natural. Each donut measures approximately 8 inches in diameter with a depth of 2–3 inches, creating smooth, organic openings rather than artificial drilled holes. Finished in a coralline color, these pieces provide a mature reef appearance immediately. Pest-free and ready to use straight out of the box, LifeRock Donuts require no curing and are safe for all marine fish and invertebrates.
