Primary Care - The fundamental basics for all marine reef aquarium systems.

Explore the world of our Primary Care range and discover the best your marine aquarium can be.  The three most important chemical elements in your reef tank are Calcium, Carbonate (Alkalinity) and Magnesium. At Coral Essentials we provide our own elements, exhaustively tested on the Sustainable Reefs coral farm. Our proprietary blend of micro traces are already included in our pre-mixed liquid elements, to ensure your reef is as balanced and enriched as ever.
