Made from calcium carbonate, it serves as an excellent buffer for calcium and alkalinity, is ready to use without curing, and is sustainably harvested to protect marine ecosystems. Its porous structure provides ideal conditions for coral frag placement and stacking. ## Description Every piece of our Dry Rock is individually selected by hand for its extraordinary appearance, unique shape, and maximum porosity. Includes 1 bottle of Purple Helix, Coralline Algae in a Bottle and instructions on how to seed your tank. Lab analysis shows that our Dry Rock contains less than half the phosphates contained within Fiji Dry Rock and up to 400% less than Pukani Dry Rock. Our Dry Rocks are the premium Swiss cheese type of Dry Rock. For every pound of Dry Rock purchased we deposit 5 pounds of reef material into the ocean, which then become living coral reefs. Every purchase is helping to build back our natural coral reefs, right here in the U.S. Your order will consist of approximately 4 medium-sized rocks that are 6-7 pounds each. Size and shapes will vary. It is recommended to have 1-2 pounds of rock per gallon of your aquarium. Our Dry Rocks are all thoroughly cleaned at our facility using high-pressure steam, but may require an additional rinse prior to placing them in your tank due to the shipping process. ## Features - 25 Pounds of ARC Reef Dry Rocks and Coralline Algae in a Bottle to Help Seed Your Tank - Calcium Carbonate Based, Makes an Excellent Calcium and Alkalinity Buffer.
