Natural alkalinity and calcium concentrations are of special importance to ensure optimum growth and well-being of many invertebrates and calcareous algae in an aquarium. In many reef aquaria an increase of alkalinity and a decrease of calcium often occur. With our Tropic Marin Alca-Balance, the alkalinity can be easily reduced to 6 to 9 dKH while the calcium concentration can be raised to a natural level simultaneously. Smooth adaptation of the water conditions to optimal KH-values. Easy to use in powdered form. Two effects in one product. No danger when overdosed. No nitrates, no phosphates.
