Marco Rock

Marco Rock Reef Saver Reef Rock The rock that put us on the map. While it might appear to look like others in the market, it is not. Our Reef Saver Rock is carefully sourced for color, porosity, and purity. Our cleaning process is also the best in the business. Accept no imitations and choose MR for the best quality dry rock in the business. All natural calcium carbonate rock that was once part of a ancient reef. Never any chemicals or additives. Often, you can spot fossilized ancient corals within the rock. Our rock is a "green" sustainable product. Because it is not harvested from a marine environment, it has no negative impact on our delicate reef or marine ecosystem. Combine this with our unique no-chemical cleaning and processing and you get great looking, pest free rock that's also environmentally friendly.

Marco Rock Reef Saver Foundation Rock Our famous Reef Saver Rock cut to offer a smooth, flat surface. We recommend placing this rock under any rock work at the boundary layer between the glass and rock display. This design allows the second layer of your scape to safely "float" above this bottom layer, promoting healthy flow around the rock work and over the substrate. Foundation Rock can be siliconed to the glass if desired. Another aquascape option is placing the rock flat side up for a shelf look.
