CaribSea Life Rock, 40 lbs., Large - 376
Give your aquarium the visual appeal and biological performance of live rock, without any impact on the worlds coral reefs. Life Rock by CaribSea is the ecologically responsible (and budget conscious) alternative to wild live rock. It is made from aragonitic base rock similar in composition to real live rock. Life Rock is color matched to real coralline algae right out of the box. You get the deep-toned, mature look without having to wait for real coralline algae to colonize. Life Rock requires no cement or curing and will not cause pH spikes. This unique base rock offers extensive macro and microporosity infused with spored bacteria to encourage beneficial bacteria to colonize on the rock as soon as you place it into your aquarium. Arrives dry, very clean, and is safe for all fish and invertebrates. Great for any saltwater aquarium setup. Lengths range from 5.5 to 9.
