Calcium, alkalinity, and pH work together in the water to reach calcite saturation, which is essential for optimum growth of corals and coralline algae. Our Tropic Marin Bio-Calcium Actif is a simple, efficient way to raise all three factors for optimal growth of corals and coralline algae while creating the ideal conditions for successful reef aquariums. Natural seawater has a calcium content of approximately 410 mg/l, an alkalinity of 6.5 dKH and a pH of 8.2. Tropic Marin Bio-Calcium Actif increases and stabilizes calcium, alkalinity and pH all at the same time. Contains all 70 trace elements in the concentrations found in natural seawater. No unnatural by-products.
