Marco Rocks Shelf Rock

Our MarcoRocks is the finest all natural aquarium rock available to the aquarium enthusiast today. It is a once live natural reef rock.

All natural calcium carbonate rock. Never any chemicals, additives. Often, you can spot fossilized ancient corals in the rocks. It comes to you pest and organic free.

This is our newest rock offering. It lends itself to that perfect shelf scape that is reminiscent of a multi-tiered reef scene. 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. For best results place these rocks over our MR Reefsaver Foundation rocks.
