All natural aragonitic calcium carbonate base rock, sliced into thin dections on both sides is the ultimate foundation for marine, reef, and African cichlid aquariums. Ideal for fragging, creating ledges and shelves, and substructures. These natural porous calcium carbonate rocks are sliced on two sides to create ledges, platforms, and caves, and are perfect for fragging corals of all sizes. Flatz can also be used to design interesting substructures, rock footers, and sandless substrate beds by tiling in across the tank bottom.
