CaribSea LifeRock is made of an aragonitic base rock, instead of the typical cement used by many other artificial rock creators. Every rock contains a network of micro and macro pores that intertwine within the rocks internal structure, creating the perfect environment for natural nitrifying bacteria. LifeRock is also infused with spored bacteria to aid in biological performance. CaribSea’s Reef Trees are perfect for the environmentally friendly aquarist. LifeRock is manmade and does not affect our natural resources, making it the perfect option for all marine fish, invertebrates, and corals.

Every LifeRock from CaribSea has an artificial coating and texture that mimics natural coralline algae after being in the ocean for years. Depending on the animals that you have in your aquarium, they may pick at the coating on the rocks which will not harm them at all, and over time live coralline algae will cover any spots on the rocks that may have had the coating picked off.

How much rock is included in this kit?

The kit includes 1 larger base rock as well as 3 primary arch pieces, and then a small spacer/cap piece. The weight will vary slightly, but you can typically expect to get about 30-35lbs of rock with your kit.

How big are the pieces?

The finished rock structure will vary in size depending on how you choose to arrange the rock pieces, but you can typically expect the finished   “sculpture” to be about 15 to 20 inches wide by about 18 inches tall.

Can I request specific shapes and sizes?

Due to the unique and pre-kitted nature of CaribSea Reef Tree kits, we are unable to take requests for specific sizes, shapes, or weights.
