Organic calcium complex
250 ml
Based on an organic calcium complex, it provides much higher bioavailability than an ionic formula, improving its assimilation by corals, providing a rich source of metabolic energy and helping to keep corals in optimal condition.
Prima Combi-ca can be used in combination with Prima Alkali to maintain calcium levels at the proper level, but it is not intended to increase calcium levels, but to improve its assimilation by corals.
If calcium is seriously depleted, you should either perform a water change or use an ionic calcium supplement such as ELOS Expert Calcium to restore natural calcium levels as in NSW. Part of our Prima line of integrators, Prima Combi-ca is designed to be easy to use, but also very precise in dosage.
Use EXTRA Ca to restore calcium levels.
Dosage:
Add 10 ml per 100 ltrs (26.4 US gal) twice weekly to increase calcium levels by 2 mg/lt (in RO water).
