What is this Marco Premium Shelf Rock Coralline 18kg from D&D?

This Marco Premium Shelf Rock Coralline is part of a range of Coralline Rock available from marine specialists D&D. This range is made up of natural calcium carbonate rocks that have been sustainably harvested from the fossilised remains of ancient coral reefs. These rocks have been coloured using a proprietary paint-free process, making them look just like aged live rock.

As a natural product, no two pieces of Coralline Rock are the same. In this 18kg box of Premium Shelf rock there are several pieces of natural plating rock that have been specially selected for hosting corals and creating stunning shelf and cave structures. These kinds of rocks are rare in fossilised reef deposits and require more preparation time than the other rocks in this range - hence the premium name tag!

Like the other rocks in this range, Premium Shelf rocks are highly textured and incredibly porous, making them perfect hosts for large colonies of beneficial bacteria. They're completely dry too, so there's no worry that any unwanted pests may be introduced to your aquarium if you choose to build a reefscape with these rocks.
