This is one of our most popular rock offerings. Formed naturally from ancient reef structures, we hand select and process the most premium structures in the Marco Rocks line to create the Premium Shelf Rock for your aquarium.

We recommend stocking the rocks as perfectly horizontal as possible and cementing them together at key junctions with our E-Marco-400 mortar. Grey is perfect for new scapes, pink for established reefs. You can also add MR Powder to hide the joints. For best results place these rocks over our MR Reefsaver Foundation rocks.
