Role:

Calcium is a fundamental component of coral biology and reef husbandry. In combination with carbonate (alkalinity), calcium forms calcium carbonate (CaCO₃), the primary structural material used by corals and other calcifying organisms to build their skeletons.

Mixing Instructions:

1. Measure - Weigh the required amount of powder
(589 grams for a 1 litre solution).

2. Prepare - Add 700 ml of RODI to your mixing container.

3. Combine - Slowly add the powder while stirring.

4. Complete - Finish by adding RODI to make a 1L final solution.

5. (Optional) - Add ECC Trace Elements as directed

1 ml of a solution added to 100 L will raise the concentration by 2 ppm
