Biologically Ideal Strontium Supplement for Reef Aquariums. 

A sufficient supply of strontium and carbon dioxide is as essential for the growth and well-being of reef-building corals as calcium. Both elements are supplied to the corals with the help of the zooxanthellae (algae) that live symbiotically within them. Bio-Strontium creates a natural environment in the aquarium and delivers strontium and carbon dioxide in a natural, biologically-available ionically balanced form
