CaribSea’s LifeRock Reef Tree kit provides the materials you need to create incredible aquascapes faster and easier than you would have thought possible. Wow your friends and family with rockscapes that turn natural-looking reef rock into gravity-defying, awe-inspiring structures. Don't worry about having to drill or hammer your rock in order to get that jutting shelf, CaribSea has taken care of the hard part. The Reef Tree kit includes several rock pieces in a variety of natural shapes and sizes, which are then drilled to accept the stabilizing rod which will hold everything in place. Once your dream rockscape is in place, you can secure the rock into a solid structure with the addition of some MarcoRocks Aquascaping Mortar.
