Our most popular rock, now offered in smaller sizes and in Coralline, perfect for DIY build projects. The rock that put us on the map. While it might appear to look like others it surely is not. Our ReefSaver 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. Our MarcoRocks is the finest all natural, once-live, calcium carbonate aquarium rock available to the aquarium enthusiast today. We never use any chemicals or additives. Often, you can spot fossilized ancient corals within the rock. Reef Saver Small pieces are approximately the size of a softball. Highly Porous and Beautifully Shaped MarcoRocks 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.
