ARC Reef Premium Live Rock requires little or no curing and are ready to be placed directly into your saltwater aquarium. ARC Reef Live Rocks contain a diverse ecosystem of life and are often the only manner in which to introduce such a vast array of life into a closed system such as an aquarium. They are never painted or dyed, their vibrant colors come from the many types of coralline living on the rocks. Our Premium version of Live Rock often contains corals, sponges, filter feeders and invertebrates such as starfish, christmas tree worms, and feather dusters. They have been growing life on them for multiple years. Our Live Rock is calcium carbonate based, which helps maintain proper pH and makes an excellent calcium and alkalinity buffer. ARC Reef Live Rocks are 100% Aquacultured and are a sustainable practice that’s beneficial to our reef systems. For every pound ordered, ARC Reef plants 10 lbs. of new coral reef material offshore. Your order not only preserves our natural reefs, it also actively aids the building of new coral reefs right here in the US. Your order will consist of approximately 4 medium-sized rocks that are 6-7 pounds each. It is recommended to have 1 to 1.5 pounds of rock per gallon of your aquarium. Please note that sizes, shapes, and colors will vary. Shipping reduces coloring by 10-12% per day of transit. Coloring will fully return within several weeks.
