Product Summary:

Tropic Marin BIO-ACTIF Calcium Supplement

Maintain the color and vitality of corals in your aquarium with the Tropic Marin BIO-ACTIF Calcium Supplement. It is a special group of compounds for saltwater aquariums to keep the corals looking new yet strong. This calcium supplement helps add biologically ideal calcium to the reef aquarium. This supplement powder supplies corals with calcium and carbonates to grow and flourish. It helps restore the crucial magnesium and calcium ratio. This supplement offers optimal skeletal growth and recreates and conditions to natural reef levels. The algae present the coral with precious carbohydrates of their own metabolism. As they photosynthesize, they use carbon dioxide from the water, which enables the coral to precipitate calcium carbonate in its skeleton. Tropic Marin Bio-Calcium is the ideal source of both calcium carbonate for the corals and carbon dioxide for the zooxanthellae. When Tropic Marin Bio-Calcium is dissolved in the aquarium, all 70 trace elements are added without any unnatural by-products being formed.
