Instant visual gratification.- These rocks have been in our grow-out tanks for many many months (up to 2 years) and are fully encrusted with crustose and coralline algae. These rocks are simple amazing! However, they do NOT have the nutrient scrubbing and slow-release of calcium benefits of our Standard eco-Live-Rock. They DO continue to leach beneficial magnesium as the limestone slowly dissolves.

Guaranteed Aptasia-free and mantis-free! Because we grow our rock in a controlled environment. We can guarantee that it will come free of pests and harmful organisms. This is a huge advantage!

Reef-safe.- Our eco-Live-Rock is tank-aquacultured, which means that coral reefs were not harmed in the production of this rock. Learn more about the environmental threats caused by harvesting Wild Live Rock.

Reef fostering.- We donate 100% of profits for reef conservation... learn more.

Unique two-step technique.- Our rocks are made with our own process that produces lots of crevices, crannies and caves... Our rock has:

• Incredibly natural-looking appearance (often nicer looking than wild rock).
• Excellent long-term source of calcium.
• Ingredients: Approximately 70% Nova Scotia granular limestone (50% aragonite, 50% magnesium carbonate) and 30% cement
• Excellent porosity and surface-to-volume ratio. See figure on the right to get an idea of how light they are compared to its size.
