CaribSea’s LifeRock Tree Extention Kit provides additional rock pieces and a support rod to add interesting features to your aquascape. Don't worry about having to drill or hammer your rock, CaribSea has taken care of the hard part. The Tree Extension Kit includes two hand-made arching rock pieces with naturally varying shapes, which are pre-drilled to accept the stabilizing rod which will hold everything in place.LifeRock is manufactured from natural base rock comprised of 97% calcium carbonate with minor and trace elements such as strontium, magnesium, and barium. Multiple coatings of engineered aragonite is carefully layered on to the base rock to maintain porosity while yielding soft muted colors of a living reef. It is then infused with bacteria using AragAlive™ technology to jump start the cycling process. With LifeRock, you can enjoy the full beauty and benefits of real live rock without unwanted hitchhikers, organics, or algae. No curing is required. With LifeRock you will get the look of an established reef from Day 1
