It's also porous, lightweight, and comes in excellent shapes, which will give your tank a natural look for both you and your aquarium inhabitants. The porous surface and crevices of Caribbean Rock causes it to have an increased surface area, which results in great places for all micro and macro life, like beneficial bacteria and copepods, to flourish and multiply.
