Our MarcoRocks is the finest all-natural aquarium rock available to the aquarium enthusiast today. It is an ever living natural stone.

All natural calcium carbonate rock. Never chemicals, additives. Often you can see fossilized ancient corals in the rocks. It is pest and biologically released.

We recommend storing the bricks as perfectly horizontal as possible and sticking them together at key intersections with our E-Marco-400 mortar. Gray is perfect for new scapes, pink for established reefs. For best results, place these stones over our MR Reefsaver Foundation stones.

Environmentally friendly sustainable stone

Our rock is a "green" sustainable product, as it is not harvested from a marine environment and does not negatively impact our delicate reef or marine ecosystem. Combine this with our unique chemical cleaning and processing and you get great looking stone, completely free of vermin and organic matter that is also environmentally friendly.

The choice of professional reef builders

Whether you're just building a saltwater fish, reef tank or freshwater tank, and even reptile environments, you'll love this rock and so will your pets. It is very porous and beautifully formed. Marco Reefsaver Premium Shelf Rock is a natural rock harvested on land from an ancient reef system that was buried when the Florida land mass was formed.
